What parts can I interchange?

[AngusJustice]

Anyone know what parts are interchangeable with my 1980 honda atc 185? can I use 185s parts, or 200s,200m,200x please let me know if you have any idea and what years I can use? thanks A.J.....p.s. can I put a bigger carb on it? Thanks again.

200x carb should be 2mm larger then a 185

but your right....basicly all 185 185s and the atc 200 parts interchange other then the stock pistons

About the only bigger carb is for a 200x and it really isn't necessary if you haven't done any other mods to the trike. The first mods you should do are an exhaust and a nice air filter. Then after those mods you will have to rejet your existing carb, but that should make an improvement in performance.

Alot of motor parts interchange between the 185 and other 185/200 models. As for other parts you will need to be more specific.

200x carb is a nice upgrade but as they said ....it would be more useful to put on a better air filter and better exhaust. then go and get a carb. if ya wanna get a little more out of that 185 slap a 200x cam in it. i did all that and more and all that stuff woke up my little 200s (basically the same as 185) engine allot. they can be quick little motors when built up and geared rite.

I have an 84 atc 200s with the cylinder that's pitted like mad but can't find a big bore piston kit for that year and model. I can find one for an 85, but is there any difference between the 84 and the 85? Could I use a bigger piston from another model like the 200m?

Thanks.
