i just bought a very clean 1985 honda 200x and i ride it daily.i love this bike but would like more power,does anybody know if a 350 motor would fit in the 200x chassis. i checked on k and n filter and they want $55,is it worth the money? i found some other after market filters for a 3rd of the price.what exhaust pipe works the best for that make? i feel guilty for ever wanting to ruin this 28 year old like new three wheeler and it runs awsome,starts on first or second kick in 30 degree weather and no smoke or oil leaks.the only thing wrong with it is the on/off switch dont work but i just full choke it to turn off.thxs for reading this. any commnts welcome.god bless u all

 

Keep it the way it is and go out and buy a 350x

 

Keep the 200x the way it is . I dont think the 350x motor would fit anyway . Check into some mods for the 200x . I think you can use a xr200 cam and carb and get some more power . I am not sure what year just google 200x mods .

 

Cobra or dg full exhaust moose pre-oiled filter rejett the carb from ebay. Web racing cam four stroke tech has a big bore kit
