Bearing Noise under sprocket cover

I have a 01 Gixxer 750 with 3,600 miles I keep hearing this scratching noise from what I thought it was the brakes but after further investigation i found out it was comming from underneath the front sprocket cover... Is this normal for gixxers or should i be really concerned... what do you guys think it could be and how pricey is it to fix.

Have you removed the sprocket cover and investigated yet?

No I havent but I am wondering if this is common for these bikes or if its something I should be really worried about it... I squirted some chain lube in there to band-ade the problem for the time being and it fixed it for now.... I really am not a good wrench so this problem is way out of my abilities.

Maybe you needed to clean/lube the chain anyway?

I am going to try taking off the over and cleaning up the are i think its a build up of the old chain lube (suzuki chain lube sucks it makes a mess of everything) and gunk... I can see a glob built up on the inside of the left ferring i can only imagine whats under that cover... I clean that up and see what happens.

only need to clean the chain, not necessarily lube it (that's what the o-ring is for). only need to lube non-o-ring chains (usually for track bikes).

i would check the sprock teeth and also check chain slack.

3k miles isn't much mileage to wear out the chain/sprocket, but do tell use what you find. or post pix. it may have picked up debri

That is true... that's why I would clean my x-ring DiD with kero fuel. It is a oil anyway so it cleans and lubes in one motion.

Check the slack on your chain it happerned to me. I happened to beat the hell out of my chain and it made the same noise. I didn't have alot of miles on it either. Got a new gold chain and no more noise.

I pulled the cover and cleaned it up with degreaser all around the sprocket... and then I noticed the a bolt and washer thingy that the speedo sensor reads was loose and bout ready to fall off... So i think a combo between the road grime and loose bolt created that noise.

So clean it all up. Apply loctite to the bolt. Re-assemble and test ride. Report back to us.

Give it a few more weeks, I haven't seen a Buell that hasn't started leaking oil. The last one started after only 500 miles.

Alot of that is due to vibrations loosening stuff. With any v-twin, especially those 45 degree jobers... you need to have a regular tightening maintance.
