:mad: :confused: :wondering WTF i hate two strokes i cannot figure out why it wont even pop!!!??? i cleaned the carburator a thousand times and tryed mixing fuel and plugging the oil injector it has spark and descent compression but if i take the carb off and push the throttle nothing comes out but my carb is full is that normal? Like i said i hate fn two strokes but i love them too. Its a 125 tri moto... I also have a 200e big red and a late 70s pacesetter its pretty much a go cart on three wheels i had no problem getting them running... anyway is it my floats adjusteed wrong or something they do float i tested them... someone please help anyone any nput would be very much appreciated:twisted:

Yep, throw it away.....

Just let some of the other members know what dumpster it's in :D

Carbs SUK gas in, they don't leak it in while you push the throttle.......

well wth i am really frustrated i already have prly 20 hours in it. I guess no one wants to help me just crack jokes i really want to ride this one its been like eight years it ran fine when i put it away i guess i just dont understand two strokes. Should the piston have a little bit of play in it does anyone kno or does that mean i need to get new rings or something cause when i was cleaning the exhaust port i could just barely jiggle the piston. i Prly just sound stupid to all you guys but im outt of ideas shhit.....

Do a compression test, make sure the carb is getting fuel. Check for spark. Let us know the results. It doesn't take much to get a 2 stroke running. Fuel, air, and spark.

well if you have air and fuel...and no pop, you prolly have no spark.

have you checked it to see if you have fire?

Just-Tri-It
08-26-2009, 06:27 PM
That 125 can be a arm killer. Sometimes the best thing is to pull it off til you can get it running and then you can usually pull start it from then on. If you can put the carb in norm settings and be sure you are getting fire before the pull. If you ever flood it, which doesn't take much, you'll never get it started with the pull rope. You'll need viagra for your arm if you keep that up.
But it's the nature of 2 stokes... when they run good they run...and when they don't run good they don't! Best to use a fresh plug and get someone to pull you off in about 3rd or 4th and watch the rope slack. I used a big hook so I could get it off and out of the way quickly when it started. If they could push you it may be better.
If you can get it going good just sell it and get something else. 2 strokes just aren't for everyone, plus it will get you hurt and that right fast if it does start running. I had a 125, a 175 and sold them and got 250 tri-z and a 350x. If you are going to stay with the 2 stoke just move on up to a tri-z or a honda 250r. They can be easier than the smaller ones imo but still need patience.
Hope this helps.

like he said check the compression but if you can move that isnt good ,clean the carb,fresh gas ,new plug,just to think off the top of my head that what i would do.

Bunnyhop
08-26-2009, 07:04 PM
Put a new spark plug in it. A fouled plug can produce spark in the open but not hot enough when fuel and compression are hitting it in the combustion chamber. It's that, or it's really flooded. Those are my two best guesses and im probably right.

08-26-2009, 07:17 PM
i bet its no spark thats what had me wore out on my 250r!!i was one step away from blasting it full of holes with my 12 guage! i know how your feeling, sometimes its best to step away and get working on it at another time,

okay i will try a new spark plug and see wut happens. i dont kno. i will have to check i just pulled the top end off and steel wooled it there was quite a bit of build up around the head gasket and its almost seperated from its three layers. Would this affect it or can i just clean it and put it back in? REally guys i appreciate the help i thought for sure everyonne was just going to ignore me and i was just going to have to figure it out for myself. I went outside and i pulled the top end off. It did run when i put it away tho (had to roll downhill) so its probably the spark plug but it does have spark.

chad712
08-26-2009, 08:00 PM
Okay yea sorry for the cussing i was frustrated. I went out and pulled the top end off and cleaned it up a bit. Yea everything is clean i can see right thru them all even my oil injectorwas clean and im not even using it lol. I am going to try some new fuel (again) and a new spark plug thanks guys I will probably be bak for more advice when i get thos two things eliminated ha. Two strokes i hate um but i love um.

what exactly did you use steel wool on?? since you have the top end off what shape is the piston in does it have good clearance?

chad712
08-26-2009, 08:15 PM
just around where the gasket was and around the spark plug int the top end had alot of build up i washed it off with some starting fluid it looks brand new. the piston looks okay no knicks or dings or chips and it has a lil bit of clearance around the piston but if you mean spark plug to pistoni it shoudl be good cause its cupped. Is it bad to use steel wool?

08-26-2009, 08:28 PM
do a simple spark plug test.
pull the plug from the cylinder ( see if it is really wet) , leave it connected to the rubber boot, make sure it is grounded by having it touching the cylinder while you pull hard. have someone watching the sparkplug for a nice fat blue spark.
If it has spark and the plug was dry, reinsert , your problem is eslewhere, but not far.
If the plug was soaking wet, get a new one, do the plug test like above to see if you are getting spark. if you have spark , you have flooded the clyinder of fuel.
with the plug out , pull the bike until the cylinder is dry ( put your finger over the spark plug hole and pull. your finger should be dry )
insert NEW plug , pull hard , and go ride :welcome:

Chad712,
Make sure that you check the plug wire. They twist into the coil and over the years of vibration the wires inside the plug wire get all jacked up and you get no spark. As far as no gas coming out of your carb when you move the throttle; a carb of this type needs vacuum to pull the fuel/air mix into the cylinder. This vacuum is created by the engine either when you are starting it or it is running. As far as float adjustment as long as the float bowl fills without coming out of the overflow it should be okay to get the thing running. The float just stops the fuel coming from the tank when the float bowl is full, as the engine uses fuel the float opens the needle/seat and the bowl fills up again. It should be adjusted to the proper level but for now as long as the bowl fills you should be good.

daniel_250r
08-26-2009, 08:53 PM
i would start checking the voltage and maybe get a new spark plug wire, i have had it were i would have spark but it only appeared to be strong and couldnt not combust fuel

daniel_250r
08-26-2009, 08:56 PM
i would put the steel wool down it leaves dust wich will score up the piston and it will wreak havoc on the bearings

u said something about starting it going downhill? do u mean like push starting it?

Lukeatc185
08-26-2009, 09:16 PM
if you had to run it downhill then pop it into gear to get it running.. what makes you think that after it sitting for a couple years it will run from the pullstart lol. anywho usualy when you need to push start it.. its a compression or a dying stator problem. get a new plug and try. if not try push starting it again. if it runs check compression and ohm your stator.

And usually, when you take the head off, you should replace the head and base gaskets! They have probably been on it since it was new!

Okay this is driving me nuts hopefully someone can help. Tir moto 125 Two stroke... have spark (new plug), compression, and the cleanest carburetor in the state. I have gas in carburator is full but it seems nothing comes out.. i cleaned the pilot and the jets and can see right thru them. When i pull it over a few times the plug is dry for some reason. the reed vavles open and close.. i just dont think any gas is coming in or something. Could it be needle valve or something? ether will make it pop but no start. Any ideas? Also sometimes when your pull starting it wil grab and try to break you whole body. WTH is that all about?:crazy:

nice 4x post, should try to start it a couple of time with choke on and then pull the spark and see if it is wet or not. if it is something else is wrong if not it could be the fuel cap clogged up or your carb or petcock that are not cleaned correctly.

Many of which were duplicate threads, not to mention all concerning the same problem.

Post some informative content on the trike and the problem. Keep it in ONE thread.

Not to mention again, in your first thread/post you said "I hate effn 2 strokes"

You may need to get someone in your area to look at it.
If you have a new plug, pull it out and see if any gas is getting to it or if it is still dry. If it is still dry you could put a squirt of gas in the hole where the plug goes and then pull the rope a few times to see if it hits. It could be any number of things and sometimes as already stated, it's best to leave it alone for awhile.
Be sure to start at the 2 basics ...does it have fire..does it have fuel...until you have these two you aint going nowhere....today..tomorrow...or any other day.
Just to get it started you may step up one plug hotter, but just to fire it up.
Fully choke it, fuel it with a squirt, replace plug and pull the rope....it should hit within a two or three pulls.
If no good and it does have fire then get a friend and pull it down the road..being careful about the cable..not very fast. Start around 4th or 5th to get going then down shift a gear at a time to round 3rd with throttle half open to full open. You have to experiment with it a bit. If it doesn't start in 6 or 7 miles you might try parting it out on ebay.
We can't get it started from this board so you have to do your homework or carry it to a shop.
Best wishes.

You should hit it with a hammer repeatedly, swear at it, post more threads about it, and then start it on fire! Be sure to post pics of it burning. J/K

Honestly, and I'm not trying to insult you, it sounds like you shouldn't be working on it. Take it to a shop and have them sort it out. Good luck.

08-27-2009, 12:55 PM
I think you need to give it a compression test to see what its at and let me know, also have you checked to make sure that the exhaust is not clogged with anything, you said that's is been sitting for eight years maybe a mouse got in the exhaust and made a nest so the engine may not be breathing correctly or its plugged with carbon and I read in one of your post that there is slop in the piston how bad, have you tried to spray starting fluid in the carb or dumping a little gas in the spark plug hole and push starting or getting a buddy to pull you behind something. By the way if you would of named the thread YT 125 help or something like that I would of jumped in sooner. If you need more help let me know.

TrailerRider
08-27-2009, 01:42 PM
as said, check compression. If you have had the head and such off (Assuming your didn't replace them gaskets as you didn't say you did) Your problem is compression. A leaky gasket topend or bottom will stop it from running right now. Change the gaskets to new ones and get new plugs (just in case) and make sure it is not flooded and give it a pull. Bet it starts..

Starting from the top

1. If old fuel is in the tank, remove the tank and drain the gas.
2. Refill the tank. Test the petcock for fuel flow.
3. Install new fuel filter.
4. Check the air filter. Is one there? If so, what brand is it. Does it effect the jetting. Research this.
5. Remove the carb--yes again.
6. Purchase a carb rebuild kit on ebay for $10-$15. Purchase new manifold gasket. Purchase new spark plug.
7. Take the carb apart, clean it with carb cleaner--again, and again, and again, and again until the whole can is gone. Get every hole you can see.
8. Rebuild the carb with the rebuild kit. Make sure the air screw is 1.5-2 turns out to start. Make sure the idle screw is high enough to allow the bike to start too. Reinstall the carb and gasket. Check the manifold too.
9. Check your head bolts. Torque them down to the proper spec
10. Compression test. Check the compression with the throttle OPEN. What's the result? I don't know about that particular engine, but 110-125 PSI may be OK.
11. Correctly gap and install the new spark plug.


When I was a kid I had a 1980 RM125 that I had to maintain, so I feel your pain. Good luck and remember that these bikes require time and money to get running.

Whoa now im not dumb guys i have checked spark and everything you can think of. I really think its has something to do with the petcock but i neeed to see. And then prime the shoot out of it. thanks for the downhill method! i have done this a few times. I mean i have done a few things here and there. mostly cars and tractors. so small engines like mowers and such are a usually a breeze. just havent been around big two strokes much that didnt run. I was just looking for some advice thank you very much. I didnt mean to post like that either i thought my computer was lagging. The frustration was from the pull starting i probably pulled over a ten thousand times. Its a new eight foot nylon rope and inside the housing was coated in rope dust. I already have to fix that again so i give up now its the chevys turn to pullstart. Before i put it away had to run it downhill cause it was hard to start with the pull. Now its just straight up impossible.

Lukeatc185
08-27-2009, 07:21 PM
spray gas into the carb try pulling it. if it wont put put put. then its not a fuel issue.. if u had to roll it down a hill to start it sounds like a stator problem. or compression.. the stator could be dying.. and its dead now maybe.

Dirtcrasher
08-27-2009, 08:26 PM
As a quick test, just to rule it out - Put your thumb over the plug hole (copyright) and give it a yank, if it farts under your thumb pretty well and or blows it off then it's good enough to get it running. Does it pull over like it has any compression? Get out your thumb :lol:

You said you've worked on allot of stuff so stick with your basics:

Spark - at the RIGHT time.

Compression - the thumb thing if you can't get a gauge. FART FART FART

As far as fuel - if the other 2 are AOK, a bit of fuel in the spark plug hole will spudder or fire it.

OR - You don't have spark at the right time or any compression.

Once it at least runs like crap for 4 seconds:

Then we can think about air leaks, plugged carb jets, muffley plugged blah blah blah.

Okay so i know im getting gas now the plug gets wet. And when i fill it and try to pull in will lock up instead of firing. I tried a couple of new plugs so my guess is its not firing at the right time or something. Any suggestions on how to adjust and were it should be?
:naughty:

old-yellow
08-30-2009, 11:30 PM
There is no way to adjusting the timing on these trikes, but I would pull the flywheel off and make sure that the flywheel key has not broke, causing it to mess up the timing, if it is locking up when you put gas in it you are dumping to much in.

lndy650
08-31-2009, 12:03 AM
dont fill it with gas just put a splash in there it dosent take much... this sounds like a compression problem check compression!!

chad712
08-31-2009, 12:53 AM
okay so i tried just a splash still nothing. It will actually burn the fuel when i do a spark test so i dunno. I think the flywheel is okay cause the brake light lights up bright when i pull the chord or does that matter? It just doesnt make sense not even a pop. Could the exhaust be stopping me cause it does smoke a lil when i pull it over?

old-yellow
08-31-2009, 01:04 AM
It does not matter if the brake light lights up because that has nothing to do with how the pick up coil senses timing, I would differently check the flywheel key to see if it broke or not and I don't get what you are talking about the exhaust smoking, it's a 2-stroke it supposed to smoke and I am still waiting to hear what the compression is at.

lndy650

08-31-2009, 01:31 AM
well i meant its not plugged but i dont have a compression tester. Its enough to blow my thumb off i cant hold it if i wanted to. Probably not where it supposed to be i have been trying everything except pulling it behind somethin which will probably work i hope. So i havent even looked at the flywheel do you know where i can get a free manual for this?

old-yellow
08-31-2009, 01:57 AM
I think that monroemike can help you with a free manual if you ask him nicely and get yourself a flywheel puller and check the flywheel key also if it can blow your finger off the spark plug hole then you should have enough compression for it to run, I think that you have a broke flywheel key.

Sounds like you flooded the crap outta it. Change the oil and pull the spark plug out and let it set over night. Then try again without putting fuel in the plug hole. If its backfiring ouut the carb or pipe or sometimes just jerking your arm back, you have a spun flywheel key. Have you looked st the reeds? Are the chipped or broken at all?

Erics350x
09-01-2009, 07:12 PM
The tard thing wasn't directed at you necessarily, but if you feel guilty. Oil is thicker than fuel and there's not normally that much fuel in the combustion area. On top of that the crank seal are how old? Not that it matters much in this case, it was just a good extra measure to prevent further damage. I'll leave this to the master, help him fix it....

How much are you willing to give nitrometh its in pretty good shape except for the front forks, they are slightly bent. All the plastics and everything are pretty good and alot of parts are like new if i cleaned them up. I would rather not sell it and put a 175 top end and piston on it. I pulled the jug off and its scored badly and so is the piston and the bottom ring is worn down. So my whole problem i believe was just compression. The oil pump must have quit working or something alot of people rode it i left it at my parents house when i moved out a long time ago. They must have hit a fence post or something. Anyway make an offer if you want i will consider but i will tell you now its not going anywhere for $50

I really like this thread. Im glad it came back. About 4 ounces of coors came flying out of my nose when he filled it up with gas. lmao. Get it running yet bud?

This was a sad thread! Less pointless comments, and more positive feedback, this guy could of had another trike back on the trail. I bet it's in pieces somewhere, forgotten about, never to return!

RB- I hear your enthusiasm :beer I wish I could save every single trike out there!

Once you've been on the boards for awhile, you realize that some people simple cannot be helped. Many people refuse to buy or download a manual and don't understand the basic functions of either a 2 or 4 stroke engine. So, you get sick of trying to help and let other posters try. But they too quickly learn that it isn't always easy to help some people......

So, unfortunately, your probably right; It may very well in pieces never to return.

Allot of ua are more than willing to help someone that helps themselves.

instead of hating the trike you prob enjoyed riding, have a friend look at it or take it to a dealer and get fixed. you will save your time which it worth more then any amount of money.

If it scored real bad and you can hold your finger over the plug hold and it doesnt pop for finger off chances are you do not have enough compression to make it fire. And chris is 100% right when he says fuel can be in the oil on a two stroke. Take the top end off and have it bored or honed and buy a piston and rings for 60 bucks. You can rebuild the entire motor for 200 bucks so simmer down

hey, 2 cycles do have a minimum compression, where they seem to be good, but they are not. they really need a tester put on them to be positive. also piston wear will effect port seal. a worn piston will let them run, but not idle, hence pull start. some of these problems could be resolved with a phone call to a problem solver. just because it ran, doesn't mean it will run now.

I know this is a somewhat old post but I was bored and thought I would throw this out there, feel free to add your comments or other things to the list if you have some.
A 2 stroke and 4 stroke do not differ much when trouble shooting starting issues. Instead of valves you have intake/exhaust ports and reeds sometimes(unless piston port or rotary)
i am not familure with this trike specifically, but on two strokes this is what you need to check.
When you say it has good compression, what is your definition of good?
First off do a compression test of the cylinder and make sure that it is not leaking compression out of bottom end seals.
Then you need...
need SPARK FUEL AIR
you have spark: i assume strong bright spark, therefore it can be assumed that your plug, plug wire, coil, cdi, stator are all functioning, clean the spark plug hole in the head and put new plug in try again
-you can check all these components with a digital multi meter if you have the specs
you have fuel: your bowl is full, but can it get anywhere from there.
- After some failed attempts at starting pull the plug it should be wet.
- if not then no fuel; if drenched then too much fuel. pull jets out again and clean with a small piece of wire if clean then adjust low speed jet accordingly
- your fuel/air screw could be set way off making your fuel/air ratio way off
- does it use a reed induction system? are they in good working order, not chipped or broke or overly weak
- is the intake boot between the carb and the motor clean, clear of debri and not cracked?
- Is there an air leak on the body of the carb?
- Is your needle moving smoothly in and out of your seal and neither is damage or bent?
- is the slide or butterfly in your carb moving freely?
- float level should not affectly starting unless
- it allows no fuel to the bowl
- way way way too much assuming your overflow tube cannot keep up or is clogged
- When you cleaned it did you install a rebuild kit with all new gaskets, seals and o rings?
- does the tip of the needle look sharp and smooth? if yes then it should be good
- is the tip of the f/a screw sharp and smooth, not flattened or bottomed out?
- make sure every piece is installed not necessarily as it came out, but correctly
I assume you have air: The carb and intake is completely free of any obstructions
- but do you have exhaust? On a 2 stroke if the exhaust is clogged, cracked, broken, missing it will mostlikely not run correctly, maybe not at all. This also applies to 4 strokes they are just not affected by this as much
If you have everything then it will start and it will run just a matter of tunning, start at stock and work your way up or down.
If it still does not start on stock settings then try starting fluid in small amounts, it will start as long as it has compression, air and spark, so then you can eliminate those from your list
Hope this helps someone out there, was just all that is in my mental check list.

I woulda bitten the bullet and taken it to the shop, let them get it going, bet it would be less than 100$...then again, if I was him, it would probably be running! :naughty:

Loved the part of filling the cylinder with gas!!! Think he actually did that??

A when I did the 88mph I was running 70% nitro and 10% castor oil it blew the clutches out shift into my last gear and how does $200 sound for the bike

Yes I am buying this for myself and for the sake of saving another 3 wheeler and some parts that are very rare on the one in my garage that is beyond saving):
