what weight of oil you running....also i've found the sound is more pronounced with synthetic vs dyno...

also, have you recently changed the spark plugs, sometimes something can fall into the cylinder and would give you that rattle too...

ACCT spring replacement

I just replaced the springs with the TOC manufacturing replacements, and man what a difference it made. I was getting some valve noise and a little timing problem. The grambo trick would do the trick, but I would have to do it every time I went for a ride. So I didn't ride much. Thanks a bunch for the info on this site, especially Diana (great website) and TOC manufacturing. Went for a great (and quiet) ride on Saturday.
