Hi John, hope you had a good time!
I bought a 1655/1650 (some interchanged parts) on e-bay and brought it home last thursday. He told me there was a noise in the rear end, been that way since he got it over a year ago. It sounds like it's coming from the left side and raps about 4-5 times per tire rev. He said it could be a bearing in the brake area......I'm just wondering where you would start looking. Take the top off?
My home # is 630-894-3952 and my cell is 630-774-2087.

Thanks for getting back to me!
