I've fallen victim to my own preaching! Have a little weeping out of the shaft oil sprocket seal and spacer after installing this belt drive. Hmmm....shouldn't do that but oh well. Also, this setup sounds like a turbo. I'm told its because of the deep grooves in the belt, front and rear sprocket. Any thoughts?
