Spacer nuts vibrating loose do tell me more any threads on this. would it be advisable to say check them after a few 100 miles granted theres maybe expansion through heat etc. got me worried now.
Put a bit of locktight on the nuts, torque them up to around 80-80 ft lb and then check them after about 100 miles and youu you shouldn't have any problems. I did that with mine and they've been on there now for about a year.
