Am I the only one to have a noisy upper chain roller? I did some searches but the solution was to change it... It's my 5th upper chain roller lol... The first one I lost it, the second one the boalt broke and the 2 others the bearings exploded. As I can remember, the oem one wasn't noisy the first year. Seriously, it's driving me crazy hearing tsk tsk tsk everytime I'm cruising at a constant speed:bonk:! Chain slack is supposed to be ok...It's worst when my gf is with me.
