Thanks to all responded. Its good to read that a re-torque might solve the problem. At 150 miles, I did have the head re-torqued and valves adjusted. Coincidently, this weekend the bike will be due for its 500 mile re-torque along with a valve adjustment. Hope this does the trick. While I'm at it, should the ignition timing be checked as well? Also, does the "ritual of turning over to free clutch" mean squeezing the clutch, lightly kick the starter and having it ratchet back to position before actually trying to kick start the bike?
