I am starting to rebuild my CJ360 Engine.
since the CJ version has no electric starter an 6 speed, i am gonna swap these over from a CB360 Donor engine.
To be done:
- Dissasemble the engine
- check: valves, springs,
- check: Cilinder, piston, rings
- check: Cam chain, tensioner, spring
- check: clutch plates, springs
- maybe drill oil path under camshaft
- swap upper cranck case with a CB one
- soda blasting combustion chamber, valves, piston
- soda blasting engine
- painting engine (thought about powder coating it, but i will stick to aerosol)
- install 6 speed gear box
- change gasket
- change oil seals
Some info from before tear down
it was running on the right cilinder only
compression test
First time i tried was cold and without some oil in the chamber.
Right: 135 psi
left: 145 psi
The second time i poured a little oil in the chambers. use a bit to much in the right cilinder.
Right: 175 psi
left: 155 psi
a complete picture of a bike did never hurt anybody
i have orderd a brown leather saddle. and i will maybe repaint the tank, not sure jet.
Disassembling the engine
sorry for the bad pictures, they where taken before i decided to post my rebuild.
The previous owner advertised the engine as rebuild 4000 miles ago, but i didn't know anything about his rebuild process, so i will have to check a lot of things (if i can get my hands on the right tools)
