Ok so Im looking for this noise.Question Is the fr. sproket supose to rattle when bolt is tight?

I have a noise in the gearbox area near the front sproket. tore down to the sproket, removed the chain and I can move the sproket with my hand and there is no greese on it at the splines. Is that normal?

 

they only noise I've ever heard of down there was the clutch basket rattling by the discs inside.. I wouldn't think the sprocket should move side to side. Just doesn't seem right.

 

the sprocket is designed to have a little side to side play. theres a reason for this too. its to help with chain alignment.

 

Thanks for the input guys. It is sounding more and more like an output shaft bearing. What a bummer. You must split the case for that one. Everything else about the bike is perfect. This sucks!!!

 

I had an undeterminable sound coming from the front sprocket area also. I could only hear it with the bike on it's centerstand and with the engine off, usually when lubing the chain. A kind of odd clicking of metal on metal. Anyway, ended up being a lodged pebble behind the sprocket.

 

Dang!! wish mine was that simple. I can put the bike on the center stand, start it and run through the gears. When I get to 5th and 6th and the wheel rpms get faster the bike starts to vibrate and it gets noisy. A muted metal to metal sound. Agh!!!

 

Bob the biker I beg to differ. A loose countershaft sprocket will wear out the splines on both the sprocket and on the transmission shaft. If for some reason the sprockets don't line up or the sprocket is loose you can you can use shims.

 

Found it!!!!! I can't beleive I could be this happy about being so wrong. I thought I had a bad output shaft bearing .Nope, not the case. I had my chain too tight. Caused a vibration and noise. It scared the hell out of me. Today I reasembled the bike and left the chain more loose than before. No noise and vibration is all but gone. I was used to shaft drive before this bike,and a chain has a diferent feel about it. I think.
