sleds an 06 m7, when cruising down the trail if i hold it anywhere between 6800-7400 rpms i can here a chattery chirpy sound comin from the clutches/belt and just figured I'd see what you guys thought. if i let the rpms drop or pin it and get it out of that range the sound goes away. its on its second primary which probably has about 2000miles on it so I'm sure its on its last leg, and it has a bdx 10.4" secondary with probably around 1000 miles on it. other than the sound in that rpm range the clutching is spot on, will hold 8-8100 rpm all day and backshifts great. any thoughts?
