After 6 hours of trail riding yesterday, i can hear the rattle coming back. its farther back now, but its at the same RPM range as before, and goes away once you increase RPM out of the range... Probably going to call the dealer and see what they say, but doubtful they will even look at it again.I had the same initial impression with the set screw fix, but after 60+ miles the vibration is getting worse again. This is all on Can Am to PROPERLY FIX for their customers.
