i dont ride hard nor fast . i think i might just stay stock and save a few bucks
 
You can get stock bore Wiseco & JE pistons. The JE has a .25 more compression at an advertised 10.5:1. If the bore is worn a lil just go with slightly overbored Wiseco, JE only offeres 4 off the shelf piston kits for these engines, 2 in stock bore & 2 in 2mm over.
 
i wonder if je could make a piston to fit the 87mm sleve from fst with a stock stroke? that would be some where around a 384cc
 
i think that will be the direction i go when i need a rebuild. but with the nitrous i have now i will more than likly get a better crank & rod anyway
 
piston, complete gasket kit, valves and seals, clutch cable , jet kit, and spark plug
