hello to everyone, I'm new to the site, and would like to get some help. I've got what sounds like a combination of a whine and a screech in between gears, its hard to tell if it screeches in 5th cause I can barely here it in 4th with the wind in my ears. It sounds like its by the rear wheel on the left side. When I pull the clutch in, the sound stops, but as I let off and go to the next gear I hear it again, until I pull in the clutch again. Any help would be greatly appreciated.
