Ok, i ordered a chain and sprokets form the local honda shop........the sprokets are fine, no problems to report. but the chain is a parts unlimited LM 520 PRO5 O-RING CHAIN that is only rated for a 400 cc engine. my xr650l has a ton op power ups such as yoshi exhaust and a hot cam......possably a bigboar and high compression piston. do u guys think i will be ok with this one or do i need to get one rated for say a 750 cc engine. the tensile strength is somewhere around 7400 pounds. do u guys think i will be ok or do i need to go over there and teach them what chains fit what bikes!
