Well ive been riding and working on mopeds for about a year now, my 78 puch maxi(2hp) has a biturbo and is in great shape.The only problem is it is slow as hell for some reason. the accel. is extremly bad and it tops out at about 25-30, the regular 2 horse maxi should go 35 and have good accel and mine only does 30 on a GOOD day and it has a biturbo! ive cleaned the carb,cylender,exhaust, the timing is right on, clutch is good. ive been riding motocross for a while now and these symptoms sound like worn rings and/or piston. How much is a new top end kit and a gasket kit? also what is this i hear about honing the cylender? will i achieve any better performence after i get the new top end and gaskets?(my head gasket is bad because when i hold the decompression lever in and put pressure on the pedals i can hear pressure coming out of the cylender) thanks ahead of time.
