185 motor swap

[bcredneck]

my step bro gave up on his 185 and gave it to me but the motor is shot and i could buy motors from a 78 dr 370 , 125cc yamaha or i could mabey borrow a 07 klx 250 motor what do you guys think would be better

[1984 honda 200s]

07 klx 250 would be whicked, but borrow???

[bcredneck]

i talked to my freind and hes dropping off the klx 250 motor tomrow he has the light and tac for it im not going to paint or clean up the trike cause the motor is brand new and it will look funny with a crap trike and kick ass motor

[bcredneck]

this motor is going to look good in the 185 the only thing i wont have is a muffler its going to be loud as f**k

[bcredneck]

and i wont have any kick start problems its got electric start

[jb2wheels]

Wow - that's going to be a lot of work. Time for a Lifan/Loncin swap. Almost a bolt in.

not mine by good info and inspiration here:
http://www.3wheelerworld.com/showthread.php?99790-lifan-200cc

I have the same engine in my 200x - I bought a $180 dirtbike with no hours (newbie owner with dirty carb) as a donor. I watch CL every day for a couple of months for a good deal.
120801

I made my own wire harnes because my X did not have one when I got it.
I had to cut the frame crosmember under the engine to clear the drain plug.
I had to cut the sprocket cover to clear the frame.
I use the China carb with bigger jets (110/40) on the X intake with the X airbox + UNI filter and Bassani pipe.

It's OHV instead of OHC but that doesn't seem to matter beacause this engine RIPS. It will smoke my other X all day. I actually put a 13T counter (12T stock) sprocket because it runs out of gear. Very cool.

Of course if $$ is no object, bolt in a CRF 230 engine. That would be fantastic.

[200XMichigan]

That seems odd to me. Is that the actual bike? How do you just borrow a motor? What happened to the Rotax?

[atctim]

no way will that motor fit in a 185! and even if it did - where would you mount the rads?

[200XMichigan]

It all makes no sense. It would make more sense to try to turn the bike into a trike. Or something. The whole thing confuses me. Finish the Rotax 399 hardtail.

[Spaulding350X]

If I'm correct that's the same motor as the mojave. I was looking to do the same swap into a 200x and there's no way it would fit with out a lot of fab work to the frame. The motor is way to tall. Plus you need somewhere to put radiators. It would be a big project. If you got it done it would be quick as the klx250 has twice power.

[bcredneck]

all he has is the motor if it dont fit ill get the 370 and if that dont fit a 125 or bigger 2 stroke no mater what happens that suckers going to fly the motor was mounted in a trimoto 175 berfore untill a high speed filp killed the frame

[bcredneck]

before every one says that motor will never fit in a trimoto look at the hackjob it the background the pic is after the crash

[bcredneck]

and the rotax is still waighting for a rear end

[Thorpe]

How many bedframes will die for this conversion?

[bcredneck]

none im not cutting the frameat all i need to make front brackects and weld something up for the back

[bcredneck]

this is the trike im using i dont know what tank im going to use yet i got a few that fit i hope one wil clear the rads

i dont know for shure but i think the 200x frame was smaller since the foot peg hight was a little lower and the top tube hight is about the same ill know in about a hour when the motor gets here and for the rads im going to find a shorter tank and have the rads on the front but steering may be a problem if it is i may mount them like a tecate

[1984 honda 200s]

id use the tank that came off the bike, what size of frame was that again?> a 185 or a 200?.. i picked up a 185S frame tonite, id like to shave the rear fender since it sticks way out in the back and such... i love the look at my 200s oem rear fenders.

[bcredneck]

its a 185 but the nice tank is a 200 the crap honda one is the original it looks way better with the 200

[bcredneck]

im not building it to look good i building it so me and the owner of the motor can beat the crap out of it the axle is a little bent and the frame has been welded a few times all the welds are good for now
we have a few jumps in mind for this

[bcredneck]

i didnt want to cut the frame but i have to now
the motor almost fits in the frame all thats in the way is the chain gard and two motor mounts in the bottom i will have to cut another tube to fit the carb but i will get a tube welded around the carb after i get the motor mounted properly

[bcredneck]

i got the motor in and lined up the way it sits in the frame it locked in place when i bolted that bracket to the front and i might not have to cut the frame to fit the carb also figered out were i want the rads to go every thing fits good so far i just need to find a tank

[bcredneck]

ive been working all night its about 2:30 all i have to do to finish it is weld up a rear motor mount find a tank mount the carb dnk if it will fit yet no matter what ill be riding this by the weekend

[bcredneck]

no way will that motor fit in a 185! and even if it did - where would you mount the rads?
thanks if you didnt say that that motor wouldnt be in there

[atctim]

thanks if you didnt say that that motor wouldnt be in there

Good luck with the gas tank fitment !!!!!!!!! Oh - and didn't you mention you are not running a exhaust on this bike??? Bye bye valves!

[bcredneck]

well the frame is getting cut to fit the carb as soon as its light out are else the neabors will trailprotrailprotrailprotrailprotrailpro again they dont like grinding in the middle of the night im going to need a realy small gas tank and the wireing is a god damb nightmare but the speed im going ill be testing it today

[bcredneck]

and there will be a straight pipe coming out of the header if the pipe i dug out of the shed dont work

[fabiodriven]

That headlight almost looks factory.

[bcredneck]

That headlight almost looks factory.
ya i just wish it mounted like factory

[bcredneck]

i just fond a tank that fits its off my pocket bike it only holds 2L but it will work for now

[bcredneck]

how much shorter is a us 90 tank theres one i could get for free in town i think it may fit or i could dig out my cr 250 tank but i dont know where it is

[bcredneck]

its running now just need to do some welding today and put a chain on it

[bcredneck]

heres what it looks like now you can see where i had to cut the tube out of the frame i already have a stronger peace to weld in there and the gas tank and the bungi straps are only temporary

[atctim]

no air filter????????????????????? you will damage that engine without an air filter!

PS - I thought you said it fit??????

[bcredneck]

im far from finished when the frame is being welded that flat metal plate is getting moved back so i can put a filter in there
and i thought the carb would fit but i had to move the motor back a bit

[fabiodriven]

Air filters are over rated anyways.

[bcredneck]

i just took it for a slow ride in the back yard the motor is jamed in there tight and wont move even thoue there only 2 bolts holding it in i cant wait till its welded and i can go for a real ride

[hang&rattle]

Why the hell did I just read through 2 1/2 pages of this thread?, WTF is wrong with me? This ain't right. How'd I get sucked into reading all this?, it don't make sense. You actually did it, but it's not real. You should take your time and put the motor in something sporty and do it right, then you can call it a 'build', this is just dumb. Do something better with your ability, this is just stupid.

I don't know about you, but I was really expecting a crash.. As large as that engine is with 2 bolts holding it in and all...

[biggyb12]

looks like something you would find on craigslist for $1500 and has 150hp and does 140mph

[fabiodriven]

I like the shifter placement. The word "optimum" comes to mind...

[Thorpe]

heres what it looks like now you can see where i had to cut the tube out of the frame i already have a stronger peace to weld in there and the gas tank and the bungi straps are only temporary

In the words of Red Green, its only temporary, unless it works?? And all the Canadians say trikes are so hard to find, its because bcredneck keeps canabalizing them....

[bcredneck]

if i had a 250r or 350x roller i would have used that but i dont so the motors in a 185 i know its retarded to have a motor like that in a hard tail but its in there and it hauls ass so its staying there till i find a better frame

[bcredneck]

i went for a rip down my street its to high geared it toped out in 5th gear i have no idea how fast i was going but it was deffinently faster than my 350x im going to need some weights mounted to the front end it lifts up way to easy and cornering is just retarded cause the trike is way to light and the axle is way to short

[Jerm1179]

more bedrails! extend the frame! lol

[bcredneck]

there are no bed rails on this trike and i plan on keeping it that way

[bcredneck]

and no hammers or duct tape were involved in this

[briano]

2 more poor pieces of machinery gave up their lives for a project that won't ever be finished and reliable.

[bcredneck]

i put a real gas tank on there untill i find my 86 cr 250 tank when i get it in going to cut a plastic seat pan to fit and make a proper seat i already know it will clear the rad since it was on the last trike this motor was in dose anyone know if a honda sproket will fit on this motor
http://www.3wheelerworld.com/attachment.php?attachmentid=120981&d=1301533280

[bcredneck]

i put a dr370 muffler on it today but the motor went to war with the chain tentioner we all know who won that 1st gear on this is as high as 3rd on the 350x 5th and 6th gear are useless unless your on a staight long road and got some major balls ive only got up to 4500rpm in 5th it redlines at 10500rpm and it was scary as h*!! i realy need a straight axle

[bcredneck]

i changed a few things then wheelied into a apple tree in 3rd the tank that was on it wont be holding gas anymore the plastics are sill ok i took em off to keep them that way
http://www.3wheelerworld.com/attachment.php?attachmentid=121088&d=1301690668

[dcreel]

Oh man.. Hopefully you put a couple more bolts into holding the engine in the frame. I want to see video of you making a hard left in 3rd gear to see how far you can sling the motor out the right side.. That would be Epic..

[RubberSalt]

Hell yeah with the engine swap!! Screw all the downers and haters. This is the kind of stuff i like. I love how everyone acts that's the problems they see are permanent. He is build and testing, you change crap as needed. I say find a sprocket that keeps you going with the wheel barely off the ground the whole time. Probably end up doing 100mph or something dumb lol

How well does the front fender clear the radiator at higher speeds? I'm guessing it would flex alot. If it did, i'd go grab some metal and make a custom front fender. A few simple bends and it would be good to go - then polish it or get it chromed out. Always fun to have 1 piece of chrome on your bike :-p

[bcredneck]

the fender is close but it dont touch and i had to use a 4ft crow bar to get thoues front bolts in so that motors not going anywere do you think i could even ride if it was moving and i dont care if some people dont like it its fast as h*!! and i love it and as rubber salt said im testing and changing things by the time im done there will be rear suspention nothing major just to handle the smaller bumps so it still feels like a hard tail and that tank and seat will not be there veary long and the rest of the motor mounts will be welded plus some braces before the real beating begins

[bcredneck]

how did i kill anything it started as a totaled klx and a 185 with a shot motor if anything i saved 2 dead peices of crap

[Thorpe]

how did i kill anything it started as a totaled klx and a 185 with a shot motor if anything i saved 2 dead peices of crap

Turned 2 pieces of crap, into one even bigger piece of crap...

[RubberSalt]

You should see if you can modify the swing arm/suspension setup from the KLX to fit the 185 frame.

[RubberSalt]

Thorpe, i have a feeling if it's not stock, it's horrible.. and that there are no engineers that can build, unless they work for someone. Seriously, is it worth saying something to try and discourage someone like that? I have to ask, how is it a piece of crap, in detail?

[Chazz of Blades]

Dude, I think it's gonna be sweet. Of course there's gonna be assholes who claim you ruin things. They've just got their panties in a wad.



How do you guys think the first 250R came about? They took something, and at first it was a POS, but over time it became the '81 R, it didn't start that way.

I think BC would actually be a pretty good designer if given all proper materials and tools to work with, and more than anyone else he tries stuff that nobody else will. Thats pretty damn respectable, and I think it's time to lay off some with the jokes. Let the man work, you never know what the end result will be.

[bcredneck]

I finally got a vid of it hauling ass down my street ill post it soon I can't now I'm on a iPod Joey was only in 4 th gear and 9000rpm he still had 1500and 2 gears to go

[Chazz of Blades]

Post that trailprotrailprotrailprotrailprotrailpro up!


I'd love to have that many different engines available to work with!

[bcredneck]

It got sold and i want a shorter swing arm with the same travel as the front because I like riding hardtails but I hate small bumps like washbord and the sharp impact from rocks basically like a bigred250 but smaller and faster since this is a endro motor with long gears I can't stand close gear motors they top out to fast

[bcredneck]

Post that trailprotrailprotrailprotrailprotrailpro up!

Im on a iPod right and can post it yet and bc is awesome for cheap to free motors if I had $100 right now I'd be making a gxs750 trike sleds here are a dime a dozen you can get 90s selds for less than 700 easy and every one has a dirtbike

[RubberSalt]

I got a couple KZ400 motors to play with, but nothing to stick them into yet.... YET

Thought about dropping the klt200 engine and putting in the kz.

[Thorpe]

I love things that are modified... And I have nothing but respect for the guys who do it with detail and care. Not slap whatever junk is laying around into a glob of crap. I believe in fit and finish, and safety. Not hanging crap together with 2 bolts, bungee corded parts and bedframes... I am yet to see anything ever get "finished". For gods sake, if you are going to do hatchet work, dont post it. And if you do decide to post it, expect to get opinions. Good, bad or indifferent. (there is a huge difference between a "Engineer" and a "cobble job")

[200XMichigan]

I'm impressed its in there. Is that a 250ES tank? Everyone wants to rag on this trike but come on guys....remember when you were young and broke and wanted to ride? For a cheap trike its pretty cool. And with the proper engine mounts it could actually end up being a good trike when finished. How funny would it be to waste a band new quad with something that looked like that. Everyone said it couldn't be done, and he did it, that counts for something in my book.

Whoever was riding it should have had a helmet on..

[bcredneck]

you can only get him to wear one if he jumping or on a long ride

[Kfx-xc-racer88]

the motor sounds good!!!

[bcredneck]

ya i realy like the dr370 pipe it sounds way better than the 20lb stock pipe
