ok so a few weeks ago i blew my rings and gouged the cylinder and piston so i order new one but the piston hit the head.. would have to order a separate special piston.. THE GRUBEE OR GT5. so i went ahead and ordered a new motor the exact same one i had.. left everything on my bike just put the motor, throttle cable, and clutch cable on it.. but idk why or how but seems like this motor has so much less power than my other one.. could it be the new carb? could the motor be angled a little different? could it be the new magneto? i had a replacement magneto on my old motor. any ideas how i could have lost so much power after buying the same motor???? thanks for reading and any advice...
