Re: 76 CB360, before & after
After reading about Giant Robots, oil misfortune. I was wondering how a guy could check the top end for oil. "just periodically" after firing up the engine for the first couple times, to ensure things in fact are flowing properly. the only thing thats coming to mind is pull the valve adj caps and peek in there as best you can?
OR, if a guy was feeling extra industrious. devise a method to put a drill on sprocket shaft. shift tranny into first...no plugs. and spin the motor after cam goes in but before head cover goes on ? oil should squirt up through journals? could that even work?
Any other thoughts?

Re: 76 CB360, before & after
Biggest issue with a 360 is remembering to fill the bath tubs up top before buttoning up the engine. Heck DON'T put the valve cover on until you have the thing IN the frame since you can spill the oil out. Next biggest is keeping RPMS down right after you start it so it has time to circulate oil.
When I did my head work this winter I had the cam shaft in and the tensioner in/adjusted and everything ready for the valve cover. I oiled the top up and then just kicked the kicker until I got oil up top, then kept kicking until I felt I had enough oil moved around. Then cleaned up the mess and glued and bolted the top down.
On my 450 I used an oil can jammed into the port on the side that feeds oil to the engine and just pumped like a mad man until I got considerable oil out of the cams. Had to leave the bottom plug out and catch the oil because it took a lot to get that job done.

Re: 76 CB360, before & after
I use a 'squirt' oil can and oil valve tops/rocker arms, only give about 5~6 pumps through inlets, remove spark plugs, kick over about 10~15 times and everything will be primed
The exhaust side gets plenty of oil due to cam rotation
I used to use a 50/50 mix of Molyslip oil treatment and engine oil but for last several years use assembly lube on cam bearings and rocker pads (pretty much the same thing but thicker)
It will get washed into sump by engine oil when running, doesn't stay in suspension (it's such a small quantity it wont cause clutch problems)

Re: 76 CB360, before & after
I kind of figure its because of that slot that is cast right next to the hole feeds that side, it just pumps the oil right into the bath tub instead of under the cam and then into the bath tub like the right side does. That's why I filled it up when I did my head mods.

Re: 76 CB360, before & after
It all sounds like a bunch of great advise and ideas! thanks.
I got tired. I went to bed at 6 last night and got up at 6 this morning. get a bit more done tonight maybe and hopefully back up at 3 again in morning. gotta get some serious work done on her. thats the plan.

Re: 76 CB360, before & after
what do you think of this. I use mobil 1 t4 motorcycle synthetic in her. thinking of just smearing a little mobil 1 synthetic grease on cam and bearings?
I can get some blue moly at work...it has been recommended for bike use from a qualified mechanic that I am growing to trust.

Re: 76 CB360, before & after
Synthetic isn't a great idea with a wet clutch and even less so after a rebuild. Synthetic is too slippery for the clutch to operate at its best and it prevents components to bedding in well (especially piston rings, should they be part of your rebuild).
