Any thoughts on the amount and viscosity of oil for the M21 telescopic forks ?
BSA service sheets say 142ml of 20wt
says 213ml ..
My forks are a bit 'clunky' on the rebound and in general...I had 220ml of 30wt engine oil in each leg.
More oil ? .. thicker oil ? to stop the 'clunkiness' .
Thanks friends ...Charlie.
