When I accelerate from a stand still, the scooter vibrates very bad, once it gets moving it accelerates very smoothly. I have a top end speed of ~65 mph. I have had this problem since the scooter was new and it now has 3,000 miles. I assumed it was a bad clutch, but someone mentioned replacing the rollers. I understand how a warped clutch outer housing could cause the problem, but I don't know enough about how the rollers work to know if this could be the problem. Could anyone give me some advise and/or explain what type clutch or roller issues I should be considering?
Thanks
