Progress today
Checked/tightened rear brake banjo bolts with torque wrench – to 15ft/lbs – as recommended by Galfer.
Removed old clip-type master link from the nasty old chain.
Used the old – now split – chain to pull the new chain around the front sprocket. Used WD40 to free up sticky rear hub (eccentric) adjuster. Adjusted rear end to forward-most position. Fitted new clip master link to the new chain.
Also have new, gold, rivet-type master link for the new chain. May either buy tool to do it myself later, or ask shop to install it.
Adjusted chain slack and retightened the rear hub pinch bolt.
Also scrubbed, primed, and painted side stand gloss black.
