You buy a new set of pistons just like you would do with a stock engine...

 

well once you get into the rotax/chettah stages u get the R in the 410cc range from sparks then we'll see who comes out on top

 

Ok you really seem to think the 250r is the fastest thing outhere...The fastest Banshee is faster than the fastest 250r this is a simple and well known fact weither you like it or not.Dont beleive me no biggie just get your *** to Glamis on T-Day and see for yourself.

 

Actually I dont see how a Banshee is faster being a 535 or whatever, a 535 SHOULD burn a 410 but doesnt? hmm i dunno...either way I wouldnt mind having either

 

Actually the fastest 350cc stock stroke stock bore Banshee on alky runs 4.12 in 300ft...Find me a 350cc 250r that can match those times...Dont waste your time searching there arent any.By the way a 535 will burn a 410 unless your name is Dennis Packard and even then...

 

thats cool i wont

 

ya obviosly but how much does an oversized cheetah piston cost... that was my point.

 

Like 40$ more than an OEM set so who cares??? If you wanna play you gotta pay...

 

how do you know how much they are?? i highly dought a 4800$ engine.. has a 120$ piston.. i couldnt be wwrong tho... but i dont think i am.

 

There is no such thing as an oversized Cheetah piston...The cylinders are nikasil plated, you just put a new set in thats all.
