when i baught my bike the guy told me it has boost ported pistons. but he also said my bike isnt ported other than whats stock. and i was wondering the same thing is there any advantages. of having the pistons over regular.

di he say that he had them boost ported? probably just looked into the intakes and saw the windows thinking that was something someone had done, because on sno-go's there aren't any wondows, but people have trimmed the skirts, trying to gain power. all that does is waste gas and cool your cylinders by increasing the initial charge, leaving less for the transfers. i doubt they were touched unless he said he had the windows modified. i wouldn't mess with the windows, because changing the height really messes with the port timing and width will weaken the piston. the only time i see this being done is when the guy doing the porting has a need to do so to complement the work he's doing, imo

i wouldnt touch the pistons. ive heard of piston skirts breaking off due to that. i dont think youre gonna gain enough from it to warrant the reliability issues.
