My motor puked some(a lot) of oil after sitting for a long time. The oil got on my belt and caused it to chirp real bad. I thought it was the primary or something. I gunked the motor to try to find the oil leak and i oversprayed onto the belt and thought I should do the sprocket too. Clean belt and no more squeak.

Oh yeah, chapstick on the edges of the belt works too...

 

I thought I had the same problem, belt chirping, turned out to be rear axle bearing going out instead.

 

Use spray deoderant with baby powder on the belt.

Stroker

 

Or maybe take the parakeet out of the saddlebags!
