Need help with my 200x!

[Ksweeney092]

Hey guys! I'm new to this site so take it easy on me! Just purchased a 1985 200x and I'm having some issues. It has a 250 top end and a 200x bottom end. Appears to have a 200x carb on it, although I'm not sure if they differ from the 200 to the 250. Anyways, it will start right up, but I've noticed when the choke is on it won't run and when the choke is off it will idle but hitting the gas bogs it ans has barely and power. It runs the best on half choke with great throttle response but it's totally gutless. it has loads of compression..
I noticed the gas tank was pretty rusty inside after draining it and the gas was a dark grey. Yuck! Also I see there is no boot from the carb to the air cleaner. To me this sounds like a lean condition. What could be causing this? The dirty fuel? A dirty carb? The carb boot ? Wrong size carb? Off jetting? Please any advice would be highly appreciated. Would really like to get this thing running like a raped ape!

Any and all of the above can cause lean conditions, based on the tank description, a jet is plugged up, or both jets are plugged. A different cylinder or exhaust effects carb jetting too, so the jets could be wrong as well.

Can we get photos of the engine? I'm not sure of a 250cc top end that bolts on the 200x engine, maybe there's a big bore kit or something, but I'm not aware of a stock top end swap though.

[Ksweeney092]

Okay I will take pics when I get home. Now that you say that, the guy did tell me it's a 250 big bore. So what should I do? Buy the air box boot and clean the carb, will that fix it or will i still have to jet up? Forgot to mention it has a DG slip on too

[Ksweeney092]

And how do I post pictures lol

[shortline10]

Probably just a .50 over bore . Which would give you around 3 more cc not 50cc lol .
Sounds like the carburetor just needs serviced .

[Ksweeney092]

I'm just going by what he told me lol and he did say the carb was brand new upon rebuild but if he was running it with crap gas you're probably right. So the carb boot and jetting wouldn't make a difference is what you're saying? Just a carb servicing?

[shortline10]

Brand new china carburetor ?
Theirs your problem right their :lol:
Find an original 200x carburetor and put a shindy carburetor kit in it and all will be happy .

China Carb = DooDoo

[Ksweeney092]

I've owned the trike for one day, I have no idea what he had put on it. Where can I find a genuine 200x carb? Any ideas? For a reasonable price

[shortline10]

eBay or possibly here is your best bet to find a good used carburetor . The OEM Honda carburetor has been discontinued for ever .

[Ksweeney092]

Would you happen to know what carb exactly I'm looking for?7

[ps2fixer]

When I mentioned all of the above, I mean length of intake, size of intake etc effects jetting and air flow. Old vs new of the same size/shape wouldn't do anything unless it had a crack in it.

China carbs are hit and miss at best.

For the stock 200x carbs, they would be marked PD62A for 83, and PD62B for 84-85.

If you're using a cellphone, I can't be of much help for posting photos, but on pc, click "go advanced" at the bottom right of the quick reply box, then down a ways below the reply box is a "Manage Attachments" button, click that and a pop up some come up. Top right corner of the pop up says add files. You can click the + to get more photos to upload at once. Once you choose your photos, wait for them to pop up in the bottom bar and just close the window out. The Manage Attachments section should show the image details there. Once you hit submit reply, the photos will be at the bottom of your post. More advanced you can use the "insert inline" on the pop up to put the photos within the reply, but easier to just ignore that feature.

Update: got her running great with this "China carb". A good cleaning and few adjustments did it. Now a new issue aroused. Clutch seems to slip under heavy throttle. Unless engine has been running for a bit and real warm. The oil does seem to be old and grayish looking. If I change oil will this fix the issue? What oil is recommended. Also do you think a clutch plate kit would fix this? Any advice? Also clutch cable is adjusted properly with slack.

[Gabriel]

Find the right carb on ebay and ask YaegerB to pick out your carb kit. Drop ship both to him and wait a couple weeks. You get a carburetor as good as any in the country.

[Ksweeney092]

The carb isn't the issue now it's the clutch. Refer to my last reply

[Dirtcrasher]

And how do I post pictures lol


Yeah, the 250 top end sounds a bit odd. Maybe the dude you bought it from bored the snot out of it...

Pictures on 3WW - By far the easiest way I have found is to use Tap-A-Talk app.

Sometimes I type all my words in, post the message, then add pics from my stupid, err, smart phone...

[Gabriel]

Why wouldn't you change the oil anyway? If it's not as clean as when it goes in, it oughta come out. ....a quart of oil isn't exactly a financial burden.

[ironchop]

We can't tell you if an oil change will fix it or if a clutch plate kit would fix it. That would be guesswork at best... It's impossible to correctly diagnose a motor that you haven't taken apart yet and inspected... You can't tell whether you really need new fiber plates or not until you take the clutch assembly apart, pull out all the plates and measure the thicknesses. $70 is allot of money to gamble without looking at the old parts first before you buy new stuff.

The oil came out GRAYish? Was it kind of milky colored like gray mixed oil? Sounds like you might have had water in the oil.

We don't know what kind of oil was in the machine, it's possible it's the wrong stuff, could change the oil and run it for a short time with the right grade oil, then drain and fill again to help flush out the old + the possible water.

If it's the right oil and it's slipping, than at best the guess would be the clutch plates are worn. You could just take the side cover off and install a new $10 gasket to check the clutch fibers to see if they are in spec or not. You'd still want to replace the oil in either case, oil is never normally gray colored.

Looks like these were all done with new oil.

Here's another photo of more used oil and less mixed up.

Oil is normally amber/yellowish colored (new), and slowly turns brown and eventurally turns to black when it's gone way too long since an oil change. When it gets so black it isn't even shiny is when mechanics say the oil is charcoal black. I have a family member that buys new cars and never changes the oil for 100k miles, then sells the car. Always look at the oil of cars you're looking to buy, same with atv's.

[Ksweeney092]

Would you happen to know what thickness clutch plates should be? And buying a quart of oil isn't the issue. I have oil.. I was planning on changing it anyways. The bike is at my parents house and I'm not always there to mess with it. Just trying to figure a few things out before I do decide to tinker with it

[shortline10]

The 200x is very sensitive to synthetic oil , that being said if it ever had synthetic oil or conventional car oil in it the plates are junk now , also fiber plates get hard and slip as well .
If your clutch is slipping no matter the thickness of the plates it needs a rebuild .
New fibers / steels and I recommend vesrah heavy duty springs .
Most importantly use a good non synthetic wet clutch oil like Honda GN4 10w-40

Here's the service specs. You can get a copy of the service manual here -> http://www.oscarmayer.net/atc/manuals/

@Ksweeney092

Any chance you could post some photos of your machine/engine. I just ran into a person on ebay that has a 250 engine going into an 85 200x frame, maybe it's the same engine as yours? I know basically nothing about it, but if it's a direct bolt in, might be an interesting option for 200 series machine owners. I'm guessing it might be a china clone engine of some sort.

Would be pretty cool if it was a bolt in or minor mod engine especially if it shares some parts with the honda like you were saying in another post if thats the same engine

[ps2fixer]

Based on the person that messaged me about his 200x with a 250c engine, he's installed that exact engine in his 200x frame, so unless he's lying, it fits in the 200x frame. It comes with a harness and most supporting electronics, I noticed the battery cables, and left handle bar controls are not included in the kit. The person was buying an ignition switch off me for this machine and realized the connectors wouldn't match up to the aftermarket harness.

Since it's a CRF clone, I suspect the actual Honda CRF engines uses the same or similar engine mounting pattern.

Here's a build thread confirming the CRF idea, well post build thread xD.
