Set Yamaha R6 Cam Timing

Step 1. With the engine out of the motorcycle, remove the bolts holding the cylinder head cover in place on top of the motor and then remove the cover itself.

Step 2. Remove the oil pump cover located at the lower right front of the motor. Keep a note of where the various brackets and retaining clips are located, so you can reinstall them on the correct bolts later.

Step 3. Remove the spark plugs. This will make turning the engine over much easier.

Step 4. Look for the timing mark (T-mark) on the timing chain rotor, and the mark on the crankcase to the left of the sprocket. Rotate the timing chain rotor clockwise using a 14mm socket on the rotor nut, until the T-mark and the engine mark are aligned.

Step 5. Check if the engine is at top dead center (TDC). Do this by looking at the camshaft lobes closest to the timing chain. If the lobes are pointing up, the engine is at TDC. If the lobes are pointing down, the engine is at bottom dead center, and you'll have to rotate the timing chain rotor again until the marks are aligned.

Step 6. Once the engine is at TDC, check if the timing marks on the two cam chain sprockets are level with the crankcase. If the T-mark is properly aligned; the engine is at TDC; and the timing chain rotor timing marks are level with the crankcase, your Yamaha R6's cam timing is correctly set. If the cam chain sprocket timing marks are NOT level with the crankcase, the timing is incorrectly set and will need to be adjusted.

Step 7. To adjust the cam timing on a Yamaha R6, you'll have to lift the cam chain sprockets off their camshafts, then lift the chain off the sprockets and move the chain accordingly. Usually if the timing is not set right, it's because the cam chain has jumped a tooth on a sprocket, so the necessary chain adjustment will be small.

Step 8. With the timing correctly set, reinstall the oil pump cover, the cylinder head cover and the spark plugs. You will need to install a new oil pump cover gasket and cylinder head cover gasket. Now is also an ideal time to replace the old spark plugs with a new set.
