This is the kit I went with off of Gasman's recommendation... he swore by them.. I've had no issues though I haven't put but 1500 miles or so on them

the chain comes pre-cut to the right length for the sprocket size you order.
are you gonna change the gearing at all? if so also order a spedo healer... so your not rack'n up extra miles
