I got the roller (friction) drive kit yesterday from bikemotorparts.com, and installed it in a matter of hours. I had problems with the motor mount bolts being too long, so I had to find enough washers to use as spacers.
When I took it out for a test ride, I gave it a little gas. The clutch and clutch drum gave out a loud rattle, like a bolt hitting the clutch drum. The bike runs, the motor is good, but the clutch is really noisy. Only when I'm at full throttle does the rattling go away, so this tells me the clutch is fully engaged onto the clutch drum.
Now I'm thinking the clutch on the motor isn't compatible with this type of clutch drum. But they're both 78mm components. The motor is a 40cc Mitsubishi 2-stroke.
Can anybody tell me what's causing this rattling noise?
