    78 GS 750 Rebuild

    I did cut back on the hardener a bit, but it seems not enough. I read in one of your old paint threads that you would start sanding while it was still soft, but by the time I did the last section/batch the first section was already rock solid. It has been pretty warm, but I have an AC unit in...

    Ok, I'll post a photo. Here's what it looked like on the last attempt. Got a lot of this knocked down, but man are my sanding muscles sore... 20180811_200308 by samL9, on Flickr

    Here?s what impatience got me...

    Or just switch to studs and nuts... I was one of the lucky few who had them all come out with no issues, so I just cleaned them up and reused them.

    78 GS 750 Rebuild

    I'm not even going to post a picture of how horrible this last attempt turned out. I got the whole thing covered, but it was not a pretty sight. I've been sanding for a while, and I'm starting to get it looking like a motorcycle tank again. So I've come to the conclusion that I should not try to...

    78 GS 750 Rebuild

    OK, so I took the tank back to the radiator shop last week to redo. There was some gunk in the coating, and there were a few spots where the coating was missing and already starting to rust. They reblasted, recoated, and it's in much better shape now. On to the paint prep. I sanded with 80...

    I forgot that I posted this, but 4 months later here I am... Reading through Pete's entire thread again (the paint portions at least) before I head out to the garage to continue the beginning stages of paint prep. I was on the fence between doing it myself and farming it out, and went back...

    Thanks for the SH775 advice and more

    Hi Jorgeno. I too have received a lot of great info and advice from this site over the years. I hope you stick around. You should post a little something about yourself over in the GS Owners forum, and maybe post a few pictures of your bike.

    Swing Arm Bearing Removal ?

    Like others said, heat with a propane torch and then a BFH. Mine were very stubborn, so I CAREFULLY cut them up with a Dremel and pulled them out after they were mangled. Very high chance of cutting into your swingarm if you do it that way though... I was lucky.

    1978 GS750EC Caliper Piston source?

    I clicked on this thread to recommend Wemoto as well. I see a couple of folks already beat me to it. Their website is a bit rough to navigate, but their customer service is top notch. I have the same bike and just went through the same thing. Make sure you order 38x40mm pistons. The 77 and...

    Gummy residue in tank...help

    Not trying to thread jack here, but I just got this done recently. Looks like there's some sand particles in the epoxy coating as if they didn't get it all out after blasting, but before coating? Any of yours come back like that? Should I be concerned about it, or it's encapsulated in the...

    but basically, I'm good with the condition of the top side and I am being overly cautious.

    78 GS 750 Rebuild

    ohhhhh.... I just re-read this. I missed the spray can part. So you're saying either move quick with the body filler on bare metal, or get a spray can of epoxy primer, since most of it will be sanded off when I do the body work any way... do I have that right?

    78 GS 750 Rebuild

    It does seem like I'm fighting a losing battle here with rust. I don't get it all, so it sits overnight. In the morning there's more flash rust... The rep at the paint store recommended an etch primer, which would have to go over the body filler. So it would be filler on bare metal, etch...

    78 GS 750 Rebuild

    ...oh yeah, and just because. Maybe I should just clear coat it and call it a day. Actually looks pretty good bare metal. :D As you can see, I sorted out my tachometer bezel fiasco. Bought a non-working assembly off ebay for super cheap, knocked off the cobwebs (literally) and carefully removed...

    78 GS 750 Rebuild

    Obviously I have to hit the underside a bit better, but am I being overly cautious on the rest? I'm thinking leaving any rust would be a bad idea. What you can't see in the pics is that there are spots where there's some pitting, and tiny spots of rust at the bottom of the pits... I'm thinking...

    78 GS 750 Rebuild

    I hit the tank today with my random orbital sander, roloc discs on my drill, and sandpaper by hand... It's better, but I still don't feel warm and fuzzy about putting body filler on top of it or painting just yet. This was after a bit of sanding 20180801_003521 by samL9, on Flickr and...

    78 GS 750 Rebuild

    I am a bit stumped on where to start though. Like I said before, the radiator shop let my tank sit before letting me know it was done. There's quite a bit of surface rust. Most of it I can sand, but some I can't like behind the tank badge area. I had planned on using Ospho. I picked up...
