Hello, new member here, was member before, but something happened since last I logged on a while ago!
Any way I'm having a slight or maybe not so slight problem with my 74 750k, that started last year, when I start off from a dead stop, it squeels, almost a high pitched groan, sometimes loudly, but normally fairly quiet. when it first started I checked the bike out, and the only thing I could find were worn swing arm bushes, and a chain that should have been changed the year before, put new in and the groan/squeel was gone for a short while, but came back again a short while later. This spring it was pretty quiet the first few times I rode it, but was there (quietly) the last couple times.
It only happens on take off, normal riding, or coasting it's not there, and it's not there when you goose the throttle at low speeds either, can't seem to find anything wrong with the bike anywhere, it sounds great, other than some clutch rattle, the oil is clean, no sparkles, and everything feels right, no slop in the sprocket shafts that I could detect, so I'm thinking it's not a bearing.
The MAIN problem I'm having is that I can't realy tell where it's coming from, wheel or bottom rear of engine! so I don't want to just tear in and see.
anyone ever have that, and if so what was it?
Any ideas of what to look at?
