Been getting a noise from the primary and an erratic vibration, noise kinda sounds like the jetsons car for lack of a better terminology. Noise is present when clutch lever is pulled in or let out so I am ruling out the I.P.B. as I've replaced it before and the noise was totally different. I've ordered new friction discs and clutch hub bearing and am waiting to tear down untill they come in. Anyone have any ideas as to what it could be ? I'm figuring it's the clutch hub bearing or hoping so anyways. I'm trying to rule out the tranny so my next question is when you pull in the clutch with the bike in neutral is the tranny mainshaft under power or not? I'm trying to figure out if it's in the clutch or the tranny. Also want to add I'm running an AIM VPC 92t with an SE spring and stock clutch plates bike is a 2006 dyna with the 6 speed tranny. Thanks for any info. Also I just replaced the front isolator so that can be ruled out as vibration and noise are still present. Thanks for any info.
