Centrifugal clutch power loss
Thanks Biken......I expected take off to be slower and you're right it is, I have lost signifigant power and speed at the top end. I suspect the clutch is not expanding all the way to drive at full speed.Possibly defective bearings or internal springs. I contacted Powerking and they promptly shipped a new clutch to me under warranty. It hasn't arrived yet, expected tomorrow. I'll post results when I get it installed and see if it makes a difference. PowerKing has been great to deal with, prompt shipment, fair pricing, and courteous service and quick with that too. I'd recommend Zoombicycles to anyone, I just ordered a new centrifugal and pullstarter for the second bike. Wider crank is from bicycle-engines.com. they too have been prompt and courteous and the quality is good. The pull start and centrifugal is great for anyone in the city with respiratory distress, much easier on the lungs and heart.
