Looking good man!
I'm going to go ahead and be that dick that says it...but those pods are junk. They are going to make for a tuning Nightmare, and with the open exhaust, you'll never make it run right...

Front brake lever came in the mail, picked up a universal bleeder valve from Napa. I top off the resivour with fluid and bled the air out of the lines and had front the front brakes working, rode for a couple hours and they functioned beautifully. Came out to go for a ride the next day and front brakes stick first time I use them, I tried opening the bleeder valve and checking to make sure the fluid return hole isn't clogged. The fluid return wasn't clogged and opening the bleeder valve did nothing so I tore the caliper apart cleaned and lubed everything and put It all back together there was corrosion that was preventing the piston from moving freely and once I cleaned that all out and put
It back together it all worked again.

Ignition switch came in the mail, plugged it in and got everything wired up. Electrical system is now functional and seems to be recharging as it should.

Laid fiberglass over my seat mold, seat turned out pretty cool. I still need to trim away some of the extra fiberglass (about two inches around the bottom and front), lay down another layer, and sand it all smooth but I am pleased with the overall shape.

Got lots of new parts in, cut my plug wires off a couple inches outside the coil housing striped the wires and soldered in new accel plug wires to replace the old hard and cracked ones. The hardened core of my old wire wasn't holding the screw in type plug caps as it should. New NGK resistor plug caps, looks a lot better and it's nice to not have to worry as much about cracking a brittle plug wire when working on other things. started the bike up and it's running  great

Polished stator cover, next piece I'm going to polish when I get a chance is the oil pump/front sprocket cover.

Started to grind off all the brackets on the frame, cut the tail section of the frame and welded in a cafe hoop. Still need to go back and clean up my welds but the hoop Is solid and holds the weight of the bike.

Attached my cafe seat today, cut all brackets off the frame then welded four threaded plugs onto the rails to use as mounting points for my seat, these are the threaded pieces I used

Cut the fiberglass seat down some flatted out the bottom and front, then traced it on a 1" thick board and cut out a seat pan.

Lined the seat up and drilled holes through to match up with the threaded plugs, put some tapered head flush mount type bolts through the seat then through a 1/4 inch rubber washer between the wooden seat pan and the frame mounts and tightened It down. still need to drill two more holes towards the back of the seat, right before the hump to put last two bots, Seat Is very solid.

Reset all my valve clearances this weekend, finished wrapping and painting my headers, and began to modify a cb360 tank to fit my bike

Nice build. I've got a '72 I'm finishing up, and would love to hear more on how your tuning is going. I've ditched the airbox for pods (for now) and want to run a more open exhaust. Also have 85 mains, left the stock 35 pilots. What kind of adjustments have you had to make? Is it a pain to cold start?

well, life got busy as it sometimes does and with school and a job my project got pushed off to the side for awhile but i have recently dove back into it.  :D so when I last updated this thread the bike was fully functional but quite ugly. I have since taken everything apart to be cleaned/painted/polished. I think modifying the cb360 tank is going to be more trouble than it is worth and I really want to get this thing back on the road so I am abandoning the idea of modifying it for my bike.

so here is the frame after disassembly, sandblasting, and primer. I used dupli-color liquid auto body primer and a small gravity fed kobalt spray gun from lowes and was quite pleased with the results.
