Have had what I consider louder then normal valve train noise for some time. Adjusted several times, seemed to help but never was quit satisfied with the extent of the noise. One other problem I've been having was cycle walking with clutch engaged. Adjusted several times, finely pulled the primary cover and found to have a loose clutch hub nut. Now the amazing thing is when I took the cycle for a test ride, not only was the bike shifting great, and finding neutral was a breeze, but what I thought was valve train noise or piston slap, was the the clutch being loose probably moving around transmitting the sound throughout the engine, engine still makes a bit of noise, but no where near the sound it was making before the clutch nut tightening.
Moral of the story, if you have what sounds like valve train noise and clutch problems, check the clutch hub nut, might help both.

Yep got in the habit of checking the hub nut each time I change the primary oil. Peace of mind.

This happen to me and the dealer seems like they are having problems getting back to normal. BDM approved the replacement of the clutch assembly because the hub nut came loose. Once they replaced the clutch assembly the trans started slipping, so they ordered the clutch plate and spring. Installed that still was slipping. BDM contacted dealer after the dealer contacted them and said they are sending more parts because they have been having problems with defective springs. Bike has been in the shop 3 1/2 weeks now.

3 1/2 weeks! Defective parts! WTF! I understand not everyone is a mechanic, that's why I do my own work. It took me all of about 2 hours to be up and running.
