- Start your removal by turning the piston to bottom dead center.
- I recommend opening the Service & Torque Specs in a new tab for easy reference.
- If you need parts and tools, make sure to buy them here!
- Pictures with captions are after the steps below.
- If you need any help don’t hesitate to ask!
- Remove the right cylinder cover, and loosen the left valve cover while the cylinder is still mounted.
- Mark the four cylinder base nuts 1 through 4 to follow a consistent pattern.
- Loosen the cylinder base nuts ¼ turn at a time to avoid binding, take as many passes as you need.
- Tap the cylinder with a mallet in multiple locations.
- While standing on the left side of your bike, slowly raise the cylinder up to expose the alignment dowels, and stuff a clean shop cloth into the crankcase opening.
- DO NOT TWIST THE CYLINDER!
If your dowels are seated on the studs, remove the cylinder. If the dowels are in the cylinder, make sure they don’t fall into the crankcase!
- You may experience binding on the left side of the cylinder due to seized alignment dowels.
- If your cylinder is seized to the stud, use PB blaster and patience.
- Remove the alignment dowels, and any loose gasket material immediately following cylinder removal.
