Book Excerpt: 1975-1984 Yamaha XS250, XS360, XS400 SOHC Twin Repair Manual IGNITION SYSTEM

CONTACT BREAKER POINTS: REMOVAL, RENOVATION AND REPLACEMENT

1. If the contact breaker points are burned, pitted or badly worn, they should be removed for dressing. If it is necessary to remove a substantial amount of material before the faces can be restored, the points should be renewed.
2. To remove the contact breaker points, unclip the contact breaker leads at their snap connectors. Remove the four slot headed screws thereby releasing both the contact breakers. Do not unscrew the two crosshead screws that retain the contact breaker back plate, otherwise the ignition will have to be retimed. The contact breakers can themsellves be separated by removing their circlip and washers and pulling the movable point off the pin, to facilitate inspection and cleaning.

ENGINE, CLUTCH AND GEARBOX

DISMANTLING THE ENGINE/GEARBOX: REMOVING THE GEARCHANGE MECHANISM

1. Pull the rubber boot from the left-hand end of the gearchange shaft and pry off the 'E' clip, removing it, together with the washer. Withdraw the shaft from the right-hand side of the engine and lift the small shouldered pivot bush from the stub shaft projecting from the gear selector arm. The arm is retained on the extended front gear selector fork rod by an 'E' clip. Remove the 'E' clip and hold the two pawl arms out, away from the change drum pins, to allow removal of the arm.
2. Loosen and remove the four screws which hold the two small plates either side of the change drum end. These screws are very tight and will require a concerted attempt to remove them. Special care should be taken when loosening the dome headed screws as the heads are easily damaged.
