Engine rebuild kit for the Honda XL600R 1983-1987. Time to rebuild? If you're diving in and doing a rebuild, replacing engine cover gaskets and replacing seals this is a great kit to have on hand! The piston rings are for the stock bore.
Note: This gasket set comes with a reproduction of valve cover gasket 12391-MG2-790 which was used on models from '84 and up. If you have an '83 XL600R either purchase Honda part 12391-MG3-004 separately (we do not carry it) or modify the gasket that comes in the kit.
- Press your seals in straight with a seal driver or a socket with a slightly smaller OD than the seal. Both surfaces must be free of dirt to create an oil tight seal.
- All sealing surfaces for gaskets must be clean and flat to make a proper seal, sometimes non-hardening sealant is necessary.
- Be very careful when installing the cylinder over new rings, it's helpful to have the proper tool to keep the rings compressed as you lower the cylinder over the pistons. Try to use only plastic tipped tools to prevent from scratching aluminum surfaces.
- The Letter stamped on the top two rings should be facing up when installing them and stagger the ring gaps according to the manual.
Piston Ring Order:
Top Compression Ring (silver outer rim)
Second Ring (black outer rim)
Bottom Rings (3 pieces - Spacer in the middle - 1 thin wiper ring on either side)
