Took the Dubya for a 340 km trip and it went beautifully around Lincolnshire and the Peaks (not far from Bergs again, went through Clay Cross!!
Although the trip was faultless, and the bike was excellent, I noticed that as the bike got hotter, I could hear clinking noises from the right hand side of the engine. I've done a search, but no joy really. One suggestion was that it could be clutch chatter, or something rattling around the clutch basket, or clutch plates rattling for some reason. I think I've had it before but not as loud (can hear it clearly through the helment). Clutch operation is generally fine, very, very occasional brief slip, but this has only happened twice before. Noise is worse at acceleration in gears 1-3 but not 4 and 5. Could hear it if I was in gear with the clutch in and revving the motor. When I stopped and revved it out of gear, couldn't hear anything.
I did think it could be pinking, but I've tried a mix of leaded and super unleaded with no change. Bike was reshimmed a few thousand miles ago. Sound does seem to be more clutch area than top end.
Any suggestions guys???
