Rear End Noise

RE: Rear End Noise
ORIGINAL: Streetrunner
I had a similar type noise on my '06 SG and got the same response from my dealer so like a dope I believed him and put up with the noise. Then, about a month ago I was at another dealer because I heard they have a good dyno tuner. I let him test ride my bike to see if he thought he could improve on the current tune. When he came back he pulled the bike right in the shop and adjusted the primary chain which was too tight. That was the cause of my noise. Now its quiet. He picked it right up and and I didn't even complain about it to him. My dealer was clueless!
I think the '07's have a automatic tension adjuster for the primary but you never know, there could be something wrong with the way it is working. You can't loose anything by letting them check it.

Mine wouldnt start making the noise until I rode for around 30 miles and could easily be heard over my V&H slip ons. If the noise could be described as a kinda old time sci-fi movie UFO sound effect like a continous low whinning (whir, whir, whir, whir.......) then yours sounds like mine did. Drove me nuts!

RE: Rear End Noise
Any new news on this problem my 2007 Dyna has started making a noise in the rear wheel. It started off at only 30mph but now 30mph or below and seems to be getting worse. The dealership says its the rear brakes (normal sound). But you apply the rear brake and, no change. Common sense tells me they don't understand simple physics or they don't care. Pretty disheartening since this is my first HD.

RE: Rear End Noise
i had a similar problem, mainly on slow down from 30 mph to 0. mine was belt noise. the local t-shirt shop put some stuff on the belt and it went away for
a few hundred miles or so then came back. im thinking of spraying the inside of
my rear pulley with that bed liner in a can to knock down some of the harmonics
created by the belt rotation. i'll post again to let you know how it turned out.
dont worry i got the "they all do it", too. i wonder if all the rattle in the tranny
is actuallyfrom that automatic primary chain tensioner. i seem to notice more noise under load at lower rpm. this would make thechainput a load on the tensioner somewhatbecause of the torque compensator doing its thing. that tensioner was new this year wasnt it. if it was a fixed pad like the old style there
wouldn't be any movement either way and the primary chain would always be in tension.

RE: Rear End Noise
my 07 deuce is doing it as well...i had it up on a jack the oyther day,and i found it's definately coming from the brakes...when i spin the wheel..about 70% of the revolution makes no noise whatsoever...the other 30% the rotor is rubbing on the pads...do you think it's out of lign..or possibly a wharped rotor??
