Drain forks completely, remove fork springs. Fit fork tubes exactly vertical in a vise and
compress the fork fully. Remove all the air from the fork by moving the outer tube and the damper rod 10 to 20 times slowly up and down. Top up the compressed forks with fork oil to 100mm under the edge, decompress forks and install fork springs and top nuts.

Note: Handlebar damper rubbers and bushings must be shortened for correct fit.
