I just installed a 66cc Grubee Skyhawk on my bike. I've got about 6-8 miles on the kit and ever since I first ran it, it sounds like the clutch is squealing. When I'm cruising down the road and disengage the clutch (pull the clutch lever in) with the motor running, the squealing stops, so I don't think its the wheel bearings or engine itself. Does anyone know, is there something I could oil or grease to stop this? You wouldn't put any lubrication on the actual clutch plates if its a dry clutch right? Thanks for the help!
