A whopping great engine will help :p

EDIT: Already got one of those lol..

How about an aftermarket exhaust?

[Despise]

if you have a yx150 then a yx160 crank would fit. rebore of cylinder & bigger piston will give you a bit more power too. then you got rockers and race cams, port polish bla bla bla i cod go on.

wat els do u have to have for a bigger piston
nothing. just enough sleeve to bore out the cylinder to whatever size you want. if the size is too big you may need to have it re-sleeved. How big can you go? I dont know as you dont want to put too much stress on the crank. I think no bigger than 4-5mm would be fine tho.

maybe themountain can shine more light on this subject/if any corrections

TBH, them engines are a no no.
You try to fit anything on them and they fall apart as your doing it or the engine parts dont go on properly.
