Engine rebuild kit for the CT90 Trail. 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: Does not contain the gasket for the dual range transmission, it only has the gasket for the single range transmission.
Installation Tips:

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.
