Just coming back from the beach, almost home when at a light I noticed a whining type noise from the primary on my 04 XB12R. Noise rises and lowers with rpm. Anyone else had this happen? Don't look forward to taking cover off............................................... ...................................... | ||

Mine makes the noise too in first gear, but it went away when I put the Micron on  | ||

Have you checked the primary chain to see if it's in spec? That's the first thing that I'd do. | ||

+1 on the primary chain. the "whining type noise" is usually the chain being to tight. have you had the bike serviced lately? | ||

Thanks guys, checking the primary chain was the last thing I'd check. It was adjusted approx 500 miles ago and felt in spec or just on the loose side. Made a 120+ mile trip to "Barnies" last night in Orlando and no noise. Noise started today. Checked chain and it seemed to be slightly tight, loosened and road tested a few minutes ago, seems to be normal again. ???????????????????????????????????????????? Never seen that happen before. | ||

Aldaytona, that also happened to me a little while ago. When I did my 1K service, I fooled with the primary and adjusted it too tight. I should have just left it alone. Later on, I pulled the bike back into the garage and backed the adjuster off a little and the noise went away. | ||

Never seen that happen before. Assuming the chain tension had been adjusted correctly before, this is typical for a misaligned/spreaded crankshaft. The tightest point will get tighter, the loosest point looser, because the primary sprocket gets tumbling more and more. | ||
