Engine rebuild kit for the Honda CT90 Trail. Time to rebuild? If you're diving in and doing the top end, replacing engine cover gaskets and replacing seals this is a great kit to have on hand!
NOTE: Does not contain the gasket for the dual range transmission, it only has the gasket for the single range transmission.
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.
CT90K Trail 90 - 1966-1979
Not for CT90's with Sub Transmission
Posted by Perry Edwards on 9th Jun 2019
I bought this kit to repair oil leaks on a 1970 Honda CT90K2. I found that the L/H Crankcase Cover gasket was not correct, it is correct for 90's without the high/low range sub transmission. The kit also does not include the sub transmission cover gasket,or the selector shaft O-ring. The kit did provide all of the proper seals for the sub transmission model. There are many other variations of gasket included in this kit that do and don't apply to the model, it a shame that it's missing these few key gaskets and O-ring. Kind of disappointing.
