78 GS 750 Rebuild

[Sam 78 GS750]

Also bought a welder and repaired some cracks in the seat pan. Had fun trying to weld tack strips to the seat, and finally got a spot welder which worked perfectly

Looks like some pretty good progress there Sam, but bugger on the tach cover, hopefully you can get that sorted.

I did the same method on the stock 450 clocks and managed not to break them, but it was an exercise in care and patience for sure.

[Sam 78 GS750]

So I got the seat pan and a few other bits powder coated, and dropped the seat off to get a cover made. I love to do everything myself, but I'd rather spend my time wrenching (and hopefully riding soon) than learning how to use a sewing machine lol. Most aftermarket seat covers I found weren't really what I was looking for. The guy's also recreating my foam (which was shot) in memory foam. Hopefully that will mean my wife will be comfy for more than 50 miles...

Also dropped my gas tank off at the local radiator shop to get sealed. For about 100 bucks more than the Caswell kit, they're completely sandblasting inside and out, pressure testing, fixing any pinholes, leaky seams etc., sealing the inside, and re-pressure testing. Well worth it in my opinion.

Technically, I could ride the bike right now. I'd just have nowhere to sit, and would have to hang a milk jug from the handlebars for fuel delivery. It would also be missing quite a few 'street legal' items like a headlight, turn signals, brake light, etc. Oh yeah, and foot pegs. I would have no foot pegs. I could ride it though...

...in other news, I made a mess of my inner fenders and chain guard trying to get some deep scratches and gouges out. The gouges and scratches are out. Now I need to get the sandpaper marks out. Right now, I'm thinking they weren't so bad how they were...

[Sam 78 GS750]

hmmm... plastic polish isn't cutting it... 320 and semi gloss it is.

[Sam 78 GS750]

320 sandpaper, a couple coats of primer, a wet sand, and a couple coats of semi gloss black later. Not perfect, but much better than they were... I was bound and determined to keep them as bare plastic, and just get the gouges out and polish them. I was thinking it would be much easier to maintain than if I painted them. It just wasn't in the cards though.

Nice work Sam! Cleaning up plastic bits without painting is tough... especially when it gets that faded/used look.

[Sam 78 GS750]

I found that out after a bit of wasted effort, Pete. I was able to get some smaller plastic pieces looking pretty good with plastic polish, but these were too big and too far gone I think.

I look at everything like this that I have to paint as practice for when I paint the tank, side covers, and tail piece. It's a bit of a daunting task for me... Hopefully I can get them looking half as good as you did with your Kat.

As long as you spend the time getting the prep work right, your paint will be fine, it's the easiest part

You'll only learn by doing though, and for a first time just be prepared to get something wrong and needing to re-do it. Nothing wrong with that, just be patient and don't expect perfect results first time out.

So I got my tank back from the radiator shop yesterday... Not 100% pleased. Their website showed that they were a Gas Tank Renu place, which had great reviews online. Their website shows a red interior coating. What I got back is white, which makes me think Kreem... They also didn't call when it was done, so it sat in the shop for a few days. There's quite a bit of surface rust. The coating's also covering the petcock threads. I'm hesitant to use a thread chaser/tap there, but I may have no choice
