The left upper sprocket of my idler chain ... the one on the brake disk ... is worn. When I replace it, is it advisable to replace the idler chain on that side, too? Also, would it be advisable to replace the right side disk brake sprocket and chain at the same time ... even though it might not be worn as much. I was wondering how a new sprocket and chain on one side might affect the adjustment tension if I leave the old one on the right side.
I notice the teeth on the lower sprocket on the left side has some wear as well. How hard is it to replace that one? Also, I'm pretty sure I might have to remove the clutch as well to get that disk brake off (maybe driven and drive to make it easier) so how how much are all the nuts torqued down ... on clutch and disk brake?
I've edited but can't seem to get the word 'socket' changed to 'sprocket' in the Thread title. Sorry for any confusion that may cause.
