[QUOTE="JonV, post: 147217, member: 24509"] my son races both the 80 and supermini classes. last week we had a catastrophic engine filure, so now is a good time to make this thing rip. next year will be a new bike, and this ride will most likely become a full supermini. he rides am/exp and is a mid-top powerband rider. we will need to replace (or repair) the cylinder. what would be the best motor combination for this bike and be ama legal? (or should i ditch it and get a kx85) mods now in place are a pc pipe / shorty silencer,boyesen pro series reeds, mild port cleanup, 27.5mm bore carb. will the kx85 top end assembly interchange or is an overbore / stroke setup better. are PVL ignitions worth the cake or will an 85 black box net any gains any help is greatly appreciated [/QUOTE]
