The bike is in pieces in my garage at present. I’m having the engine cases vapor-blasted to remove 47 years of grime and oxidation.
Interestingly, there is no oil filter to change on this bike. It doesn’t have one. Instead, it has a centrifugal filter “cup” mounted horizontally on the end of the crankshaft. Oil is pumped into it and as it spins, the nasty stuff is flung onto the wall of the cup. You need to pull the RH engine case to clean it, but it’s easy to do. Considering these old Hondas are fairly bulletproof, I imagine it’s a pretty effective design.
