Help please I've installed a 80cc motor kit from BOY GO FAST and I am having trouble getting the clutch to engage. I had a problem with the magnito magnet but shimmed it with an extra washer to get it to turn I checked the crank and the clutch shafts and they seem to turn freely but the clutch seems to slip and wont turn over the motor I tried adjusting the clutch in and then backing out a hair and actually got the motor to start once but it seemed the clutch plate is slipping again where do i go from here boy go fast wont answer my e-mails thanks for any info.
