Glad to hear that the crankset is fine, thanks for the help.



As above, the chain was just cleaned as happens about every 3 weeks or around 400-500 miles. I'm trying a new lube on the recommendation of a friend who is still into motocross. It is Dupont multi-purpose spray dry wax lube w/teflon and moly that supposedly out performs other lubes by 5 to 1. Very interesting stuff read this http://www.webbikeworld.com/t2/motor...chain-lube.htm

I got an 11 oz spray can at Lowes for less than $5
