 Got the top end mostly done today. Now I can move on to timing the cam, as well as a few other odds and ends, like flipping the engine over to pull the sump, clean and inspect and replace the gasket. I can also start installing the new clutch discs, side covers, etc.

 Stock pistons with heat reflective and TFL coatings, honed the barrels, new RIK rings. Milled the head .020 and installed new 1.00 mm over intake valves and new exhaust valves, after porting and polishing. CB650 cam with adjustable cam gear.

 Got the frame and other bits back from powder coating. I dropped off the swing arm to have new bushings pressed in.
 I also had the Avon's mounted on the Lester's. I need to finish up degreeing in the cam so I can get the engine in the frame.

 I did get the backing plate all cleaned up, painted and new EBC shoes installed. And new Avon's mounted and balanced on the Lester's.

 Finally finished a seemingly never ending stretch of overtime and had a blitz day in the garage. Dad and I degree'd in the cam and got the top end assembled a couple of weeks ago. Adjusted the valves and a few other odds and ends.
 Tried the "frame over engine" method this time and that was SUPER easy. In no time at all I had a roller!

 I picked up a REALLY clean set of carbs at Barber last year. I started going through them yesterday. I pulled a couple of emulsion tubes just to check them, and generally just giving everything a good squirt of carb cleaner. I'm going to try to finish that up today and get the carbs and air box mounted.
 But I also need to cut grass. And work on the Interceptor project. And get a hair cut.

 I know. I should really be retired. There's always something to do. I'm going right back to work in the morning. As soon as my special Honda wrench shows up, I'm turning my attention to the Interceptor in hopes of getting it done for the vintage bike meet in Spencer, NC on May 6. I seriously doubt the CB will be done by then.
 Oh....and I need to get the tank and side covers dropped off, too. That way I'm not waiting on paint whenever the rest IS done.

At the pace you crank out projects, I almost assumed you were retired or independently wealthy!  Or that you were Lawrence from Office Space. ;)

Screw the grass! Mount the carbs!  >:( Chicks dig long hair, too  8)

 There! You happy now?!  ;D



 Got the carbs cleaned, bench synced, new breather hoses, overflow hoses and fuel lines. Installed the air box with new rubbers and got the battery box in. Oh, and I added oil to the crank case.
