New, chain etc
on: September 02, 2021, 02:12:47 PM
Hi today I had a new chain, new rear sprocket and rear  wheel bearings added. I had a 16t front sprocket added a couple of weeks ago. It does not have rubber.
Bike seems to have a lot more vibration on the tank and  right foot pedal. Even the foot brake is buzzing with vibration. Any ideas what check. Many thanks

Wheel alignment would be a good thing to check. Also the front sprocket not being rubber mounted may have some effect. If youve got new wheel bearings, then I cant see that being an issue, though it still could be if they were damaged or not installed correctly. Could also check the cush drive isnt worn/damaged.

Jack the rear end and with the engine, run it through the gears, be careful.

You'll find the issue.

Aside from whats already mentioned...

Whoever installed the new chain, if they didn't crimp the link properly, it will have a stiff spot only at that rivet link area and it will transfer the vibration to rider.

Chain tension could be too tight (should be 25-30mm). Try giving it a lot (like 60-70mm) of slack (only to test) and see if that helps. If yes, chain is the problem.

A solid front sprockets doesn't really add any vibration. A cheaper chain will transmit more vibes if solid sprocket is utilized tho...still, VERY small diff and not enough to cause concern.

FWIW: The older a chain gets, its best to run them with slightly more slack than normal - since older chains tend to get stiff spots in random links.
