Best Honda 200m performance mods ?

[cameronokeefe6]

I have owned my 84 Honda 200m for years now and I am wanting to see what i could do to upgrade horsepower , speed , performance , power etc and do it safely and not cause future harm to the engine.

I was thinking on getting a 200x piston, will this work and give a good power increase ?  I have heard people have done this in the past and it works great. and i was also thinking on a 200x cam , will the 200x cam fit in this engine and make a difference also does it require the upgrading of any other parts and will i have to run 91 octane instead of 87 ? has anybody run this setup before and got good results ?

I was also gonna go with a 200x carb but not sure if i have to buy an intake to hook it up or will it just bolt onto the 200m intake and fit fine ?

If anyone has any suggestions and advice on what i could do it would be greatly appreciated ! thanks in advance.

I've seen similar things done as such but not that old of a machine,if cam did fit you might have to do some filing as to piston. Jugs and pistons must match for correct ring gap,piston might fit in old jug but wouldn't allow rings to be properly seated,then before you do upgrades on top end make sure to chk bottom end I've seen cranks and rods twist, brake ,ect but other than that nothing ventured nothing gained learning what could be is half the venture.
