Cylinder Removal
- 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 turns at a time to avoid binding. Take as many passes as needed.
- Tap the cylinder with a mallet in multiple locations.
- While standing on the left side of your bike, slowly raise the cylinder 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, ensure 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.
