I have a 99 bird and I noticed that when I first start it up, in neutral with the clutch out, I hear alot of rattling coming out of the clutch cover. If I squeeze in the clutch, it goes away. After riding for awhile, the noise goes away. I've read that the clutch basket makes noise on these bikes. Is this the case, or should I look for another issue? The bike only has 24000 miles on it. Any help would be appreciated.
