The washer goes on the other end of the shaft. .....lm
I'm readying the head for placement on the engine. I want to double check that the valves don't leak, make sure that there is NO blast media in the cam gallery, and make sure the gasket registers are clean. I need to put the rotor on the crank so I can get the timing right before I put the head on. I don't want that cam chain to be incorrectly installed.
I still need to pick up some wood bleach to clean up the chrome. It's too cold to paint right now, so I'm concentrating on the things I can do. I need to go through the starter motor, clean up the wiring harness and replace some of the (bad) bullet connectors, get some new shrink tubing installed on the alternator stator wiring loom, clean and fill the engine side covers (JB Weld for the filler), polish the aluminum (Edd China says "AL-LO-MIN-EE-UM") shiny bits on the engine, and do some polishing on the wheels. So much to do yet!! I've decided that this is not really a restoration, but a major repair. The bike WILL have patina! That's okay - as Wayne Carini says, "It's only original once". I suppose I should set a target date for the bike to be running. I don't want to make this journal a multi-year writing! 1965 CB77 305 Super Hawk

I spent some quality (and frustrating) time working on the head over the last couple of days. I opened up the cam gallery to find moisture on one side and some surface rust on a cam lobe. I also found a small amount of blast media in the bearings and the rocker shafts. I totally destroyed one of the valve covers trying to get it off (it was really seized). I finally resorted to a vise grip and that soft aluminum material didn't take well to that. Now I need valve covers!
I found out I only have one cam gallery cover gasket, and there are supposed to be two (one on each side of that sheet metal plate). Adding a gasket to the shopping list (this is getting really expensive). I flushed, flushed, FLUSHED the galleries - bearings, rocker shafts, rocker arms, valve springs - with WD40. The hope was to carry off the moisture and the blast media. All seems clean and smooth now, but I'll do it again to be sure. I used some fine emory cloth on the cam lobe to clean it up and it looks fine now. I flipped the head over and filled the combustion chambers with solvent. I am concerned that one intake valve MIGHT be leaking, but I am not completely sure it was closed. I'm going to back off the adjustors and try that again. I should probably disassemble that head, but I really want to avoid doing that if I can. 1965 CB77 305 Super Hawk

Number two intake valve DEFINITELY leaks. Now I DO have to disassemble the head. AND get the valves lapped. There's more money, and time.
There are times where I think "this #@%$ old motorcycle!" and just want to chuck the whole thing. M U S T persevere!
