GSF 650 bearing problem?

I've got a 2008 bandit and for the last few hundred miles I seem to have hit a strange noise coming from the chain area. The chain is oiled up and in good condition. I initially thought it was the chain catching the plastic guide but it is tensioned correct.  

The noise sounds like a bearing failure. When I took the cover of the front sprocket I can see all teeth are present, but when I turn the rear wheel, I can feel a notchyness in the chain as it goes round the front sprocket.  Should it be smooth as I turn it?    Is there a bearing that is prone to failure behind the front sprocket?  If so, is it an easy job to change?:shock::shock:

Check chain for any tight links first, may pay you to loosen chain tension to do this.

If not it is possibly the output shaft bearing.

Might even be a rear wheel bearing, noise being transmitted through chain to front sprocket.

Hi Goulders

I think the way you are describing this notchyness,it sounds more like it is a seized link in the chain,you are right there is a large bearing behind the drive sprocket inside the gearbox crankcase.To replace this is quite a major job,drive sprocket removed,engine out,crankcase split,gearbox drive shaft removed,bearing removed and then replaced with new one,then reverse the procedure.But thoroughly check the chain first before taking any drastic action remove and replace the chain and sprocket first unless there is definite up and down side to side movement (not very slight in and out movement end float)If unsure take the bike to a motorcycle only work shop for a proper diagnosis Good Luck

Cheers fellas.  The chain does bounce around quite a lot so I suspect (hope) it's  just the chain. Might take it in tomorrow to double check as im going touring to Spain in 3 weeks!!
