2006 katana problems

[jdsanders1]

I recently bought my first bike, a 2006 katana 600 with about 13000 miles on it. Ive been riding it for a few months now but it has started making a noise, sounds like it is coming from the front sprocket, sound like a bearing or something. ive tighten the chain but that didnt work. You can really hear it when starting off. Wondering if anyone could help identify the problem.

well does the sprockets look like there in good condition or are they worn real bad. that could be a cause or it could be a bearing like said. it also could be the chain making the noise. the old stretched out chains tend to make noise.

I took the cover and chain off the other day and cleaned them both, there was a small peice of plastic inside the sprocket covering but either way the noise has stoped,, thanks for the info
