Easiest way (IMO) is by measuring your cylinder diameter with some digital calipers. Post up the width and somebody should be able to find the right piston. :thumb:



BTW welcome to DBA. :cheers:

i looked at the athena big bore kits because i once wanted one and i didnt see one positive thing about them every one that got one said it was a huge dissapointment

idk they said they expected way more power because most users said they barley felt a power increase

big bores kits alone will just create more grunt down low for the most part. If you want more hp, you should mess with compression, cams(4t), porting/polishing, pipe combos:thumb:

i vote measure with a set of dial calipers... the cylinder is supposed to have .002" of clearance for the pistons thermal expansion, so whatever piston you get, say a 54mm piston will measure almost exactly at 54mm or ~2.126" so the cylinder needs to be 2.128", thats how you decide what piston to get :thumb:
