CAMCHAIN ADJUSTMENT The camchains should be adjusted when the engine is cold. Remove the 10 socket screws (4mm Allen key) holding each cover to the head and lift off the covers. It is not necessary to disturb the two oil feed screws in the rear cover, but to remove the front cover it will be necessary to remove the two oil feed screws before sliding the cover off.
Engage top gear; by rotating the rear wheel turn the engine until the appropriate piston is at TDC o n the compression stroke, with the ignition reluctor in position A for the front cylinder.
Position B for the rear cylinder.
Slacken the chain guide adjuster screw (8mm Allen key) and move the guide until there is 3mm of movement in the top run of the chain. Check the movement when the retaining screw has been tightened by holding the chain between finger and thumb. While the covers are off, take the opportunity to remove the oil restrictors and clean any debris from the filter gauzes. When replacing the covers check that the oil restrictors and O rings are in position in each chain case. N o gasket is fitted to the cover; use a smear of silicone RTV sealant around the joint faces, taking care not to block the oil feed hole For details of screw sizes see page 24.
