Steverino's CB77Crankcase cover removal and discoveryWhen I got this bike the first thing I noticed was the original owner had drained the tank and run the carbs dry. He had also taken the time to disconnect the fuel lines from the carbs to make sure no trace of fuel remained. I was honored to be the caretaker of the machine he cared so much about. I was optimistic he had been as meticulous with the rest of the motor.
Here is a picture right after I removed the cover. KIMG0696 by Steve Steverinomeister, on Flickr The clutch and filter assemblies look pretty clean to me.

Re: Crankcase cover removal and discoveryCheck the cam timing before you take the cam chain off.
When I find engines this clean I find the timing was not correct and the engine wasn't run at all. BTW the crank nut is wrong side out. .....................lm
I'm not sure I see it either location. ...........lm
Thank You HT, Seadog and Loud Mouse for all the help.
Here is how I checked the cam timing today. Please tell me if I need to go back and do it by the book. Pressure builds on the left cylinder up to the point where LT passes by the pointer then it subsides after LT retreats away the pointer. Also, I flipped the crankshaft nut over. Thanks for that too. Here is a link to a video of when I started it up prior to disassembly. It did start to run fairly decently once I got some fuel to the right side. https://www.youtube.com/watch?v=g29gNS6g6yw About the little washer. I barely remember on the CB160's that the washer goes behind the centrifugal filter, correct? Or does it go right behind the pin. I remember when it is in the correct position the chain lines up. I know I put it in the correct spot at the time but I just don't remember which any more. Also, I switched the crankshaft nut, bevel side is now in. Correct LM? And my last question for tonight is CMSNL shows the same part number for the gasket behind the tacho drive and behind the points plate. Are they the same? There were no gaskets when I looked today, just a little form a gasket type material. Thank You for your help Steve
1 remove the points cover and stater cover.
Set rotor to "T". Look at the end of the points cam and it (the line on the end) will either be at straight up from the level of the head or down. If down turn crank until "T" is at the marker again and points cam line is up.The heavy plate in the cam sprocket should be in perfect alignment with the flat of the head. 2 Washer goes at the PIN end. 3 The nut is installed correctly now. 4 A gasket (SAME) should be at both covers. ...........................lm
