My 48cc screamed like a banshee at high RPM. I pulled off the clutch cover to polish it and lo and behold, no lube on the gears at all. Light coating of high moly grease and it is MUCH better. Try not to get any on the clutch though. That might be a bad thing.

Grease the gears. Add a layer of dense foam on the clutch cover. Use some rubber blocks between your cooling fins.
Get used to it.
