Hey! Long time no see. Also glad to have this project, especially being a GS.


So I finished the project already...


Just kidding. I hope that mine can be like that someday. It appears to be stock besides the seat and rear sets.


Got some stuff done. New to me head is on. Everything looked to be in fantastic shape. Was told it had 10,000 miles and it sure looked it. Valve clearance set and timing set. New gaskets and torqued to spec.


I've also gone through the wiring harness. I checked and cleaned the connectors. Verified all the solder joints hidden throughout are good. Replaced the bullet terminals with spade. And rewrapped the whole harness with something much nicer than the OEM electrical tape.


As it sits right now. New Delkevic 4-1 exhaust and a new to me OEM airbox seen under the bike.


I have a bunch more parts coming in. Brakes, wheel bearings, stator, reg/rec, etc. Next step is to paint the frame then I can really start piecing this back together.

You ought to look into powdercoating it

[grcamna2]

The engine cleaned-up real nice,I like how it looks with the original patina.

[Zerospirit]

My local powdercoaters are booked for weeks so thats not really an option. So I stripped it down myself and painted with VHT epoxy paint. I've only got the swingarm and rear brake arm done so far.

It's even more taken apart... Check out the new handlebar and grips though.


Man, I knew this was gonna be a project but not this much. Literally everything needs to be fixed/replaced. At this point, I just want to ride.

Next up is brakes. They are completely shot. Not even worth rebuilding. Bleeder screws snapped and pistons are rusted/pitted. Is there an easy upgrade? Or should I just get another set of OEM in good shape?

More parts on order: tires/tubes, chain/sprockets, steering head bearings, rear shocks.

Salty Monk’s adapters for the twinpot upgrade will work

Don't you need to change the forks, too, to use a dual-disk setup?

Or do you stick with a single-disk setup and just upgrade the one piston and disk?

Just replace the lower legs from a '78 or '79.

Welcome back. Where have you been hanging out?

What's the meaning behind the new name? I know life in the PNW can be tough financially, but what's knocking the spirit out of you?

I thought I read something where he made up a single disk set up but please ask him

This PNW heat wave is killer! We can't handle triple digits haha.

New tires and tubes installed. Shinko 712 in 100/90/19 and 120/80/18.


New seat. So much nicer looking than the one that came with this. It will sit about 0.5" lower than the old one which should help me out.


A closer look at the new handlebar. I will need to drill holes in it to fit the control switches. New grips too! Still some rust to clean up...


Starting to take shape. Everything is loosely put on right now so don't mind fitment.


Frame and swingarm is painted as well. New chain has arrived but still waiting for the front and rear sprockets. New front and rear wheel bearings in. Still need to do steering stem bearings. All bearings are from All Balls.

Just waiting for this heatwave to pass then I can really start to put this together.

I like the look of that seat.
Where did you get it? Got a link?

The '77 steering stem requires a machine shop modification, or replace with a '79 stem.

From this seller on eBay. I ordered it on June 5 and received it June 25. Fitment and quality seem to be really good.

Ugh... Of course. I guess steering stem bearings will have to wait for now. My machine shop is sooo booked right now. They've had an engine for one of my other projects for over two months now.

I just realized I should get new suspension. Any recommendations for front springs and rear shocks? Oil for front forks? Is a fork brace worth it?

[cowboyup3371]

The favorite front springs are Sonic Springs, a straight rate setup that aren’t bad while Hagon is still a good choice for the rear.
