How to replace motorcycle engine and filter parts

1. Confirm the part fits

Check the part against your exact model year and, where possible, your VIN. Use JASO MA/MA2 rated oil — car oils with friction modifiers can slip a wet clutch

2. Prepare the bike

Park on level ground, use paddock stands or a centre stand as required, let the engine cool, and disconnect the battery negative if you are touching wiring.

3. Remove the old part

Work in the reverse of assembly order, bagging and labelling fasteners. Expect around 16 minutes here on a easy job.

4. Fit the new part

Oil spec: JASO MA2, viscosity per the owner's manual. Fit dry unless the manual calls for grease or thread-lock, and start every fastener by hand.

5. Torque and verify

Torque every fastener to the manual value with a calibrated wrench. Never guess on brake, axle, or engine-mount hardware.

6. Test and re-check

Do a stationary function check, then a slow test ride. Re-check fasteners and settings after the first 100 km.
