1983_GS750E - Rebuild

[Motocrossx23]

^exactly!


I let my project sit for an entire 3-4 months last spring/summer, then I realized...screw it, let's get this done, and I went out to the garage and got a TON done.

I feel your pain. I'm currently staring down 5 broken bolts on my project bike. No amount of dremel carving, PB Blaster, heat, vise grips is breaking any of them loose at this point (I've done over 20 heating/spraying cycles by now) and I've had plenty of experience with broken fasteners. Hell, even the threads on the ones I removed are looking bad.

At least you got the side covers off. That's a victory.

Hang in there. We'll get through it.

Thanks for the kind words and the encouragement......it really does help

If they only were not on a part that is so heavy to move around, I would easily take it to a shop to get it done up, but the weight alone is enough to make one almost give up....

Ohh it' so close to being a parts bike....LOL

But I will occupy my time and thoughts on other parts, and get back to those 2 items at a latter date, too much time and money is now invested to give up, that is for sure.

Merry Christmas and a Happy New Year

to all you guys and gals....

Cheers

is something missing ?

is something missing ?

so I think there is something missing, around the white part where the key goes ? should there not be a cap of some sort, with indication of ON/OFF, Lock and so on ? If so anyone have one for really cheap....

Also not a lot of progress, it's Holiday time here, lots of places closed, no one is around, a couple of the bigger places are closed up for the season, so I am just fiddling around with the smaller bits and pieces, cleaning them up and getting them ready for paint....

here is the pic, and where the key is, is where I think there is something missing...

Thanks....

prepping for paint....

prepping for paint....

So I am leaving the broken bolts for the moment, I will get back to them latter, and to take my mind off, I have started to prep my various parts for painting, however I really don't know how far to strip the parts down, before I lay on the paint, do I just take off the rough spots, do I take it down to bare metal, do I just scuff up areas, and spray......?

I have attached a few pics of various parts, and various degrees of paint stripping, and prepping, question is what is right what is wrong, is there too much or too little, will not enough look like crap, and will taking it all off give me better results, but take up the next month to get it down to the bare metal on most items......

Please anyone who has done this, how far do you take it.....?

just the bad parts, that were corroded and rusted

trying not to damage the fins too much, some did get bent but I fixed them

is this enough, not enough ?

all the way on the one side

here and there

yes the pistons need to come out and be cleaned up as well.....on the inside

If you are sand blasting (looks like it), you will want to get all of the old paint off.
Either that or you will have to hand sand to blend the hi and low spots.
It will look much better if you strip them all the way. Sorry.

Thanks Daniel....

But it's not sand blasting, don't I wish......It's all done on a wire wheel so far....I guess sanding will be next to make the highs and lows blend

 

[7981GS]

You can try a hi-fill primer an possibly avoid having to blend it all together.
Perhaps several light coats? Try one part first as a test sample?

[SVSooke]

Those look like what I do.Get the rust and loose paint off with the wire wheel then paint.If there are lots of gouges I'll do more,but that is seldom done here.

 

[bakirkwold]

Its a good start. Make sure you get all the paint off the top of the caliper. And what color are they getting painted? What kind of paint?

might try the hi-fill primer, have to see where I can get it, and if it will hold up against the brake fluid, or better stripping of the old paint......yukkkkkk

I was hoping for the same, I guess I will have to paint a few parts and see how they turn out, if the ridges are very obvious, then more sanding, or the hi fill primer will need to be used, I don't see any major gouges in any of the parts so I might get lucky......

Its a good start. Make sure you get all the paint off the top of the caliper. And what color are they getting painted? What kind of paint?

the original paint is on very good, even the wire wheel don't take if off all that easily, have to really go at it, especially on the brake calipers, some of the other metal parts, it comes off easy, but hard to get into all the nook and cranies.....

Everything will go back as it was, Black.....ya I know very original.....LOL

I have found some VHT Caliper paint (for the calipers and all brake parts), some VHT roll bar paint (for all other metal parts, covers, brackets, maybe even the rims, have not decided on that yet), and VHT header paint, well this is only for the exhaust,,,,, all in black, so I think this is what I will be using.

Appliance paint on the frame itself (Thanks to SVSooke for that tip), and VHT engine paint, naturally will go on the engine

Mate I can't believe I haven't chimed in on this yet! How slack...

Anyway, when painting high temp. stuff like the caliper, follow the directions from the paint manufacturer to the letter, and make sure it's good paint.

I used 3M caliper paint on mine and followed them to the letter and it's holding fine to the caliper so far. I'm not terribly happy with the finish though as it's not what I call a satin black... I think there are much better paints out there.

As for the other parts, depending on the paint as long as you scuff up the whole surface with some sand paper then that should be good too. I used POR 15 Blackcote on my chassis parts and that was a matter of scuffing with sandpaper (I used 240 grit), spraying some Metal Ready on which gives it a good chemical bonding surface, then Blackcote brushed on.

why not get a rebuild kit (a couple o rings) tear it down ,and soak it in paint stripper, prime it n paint it, then it will be new condition ,any rubber grommets should pop out fairly easy

Thanks pete....

I guess I will have to experiment a bit too see how it will turn out, by leaving on some of the old paint, or will it need blending as mentioned, and or have it stripped down to bare metal

Yup this is another option as well, only thing is it's an expense that might not need to be done, as the seals and rings and all that good stuff seem to be in excellent condition, there were no leaks on the units at all, but once I start to remove the pistons, I just might have to get a few rebuild kits anyways....

Well, the problem with paint that I have found is any lack of proper prep at all will ruin the paint job. It will either chip or flake or look poor. I think someone said it already but follow the paint mftr's directions carefully. Properly prep the surface and make sure the surface is completely free of any and all grease, including those from your fingers (where clean gloves). You really can't get it too clean (use a good degreaser). If the underlying paint is in good condition, then prepping according to the paints instructions should be fine (they should have both painting over existing paint and bare metal instructions). You will have to blend and feather any paint to metal transitions carefully. The primer coat will tell you where you still need work. Anything you can see in the primer coat will look even worse once the paint is laid down.

Good luck and keep us posted with the results.

polish and paint

polish and paint

Well, I have been busy, as most of us working stiffs, we have the week off, and I tried to make myself busy, did things around the house, spent time with the wife and kids, and also worked on the bike.....

I tried to clean up the bits and pieces as best as I could, some got down to bare metal, others not so much, the ones not so much well they are the test parts for when I paint, to see if they will pass or not, if they don't turn out good, the rest of the part will get sanded down to bare metal and then painted.....

I need some comments and thoughts on the shocks, should I strip them down completely, or just scuff up the original paint and give em a spray with black, or strip em down and polish them ? either can be done, but I am not sure which to do ?

I am also thinking, I will need to replace all the nuts and bolts, as I put each one to the wire wheel, they came up nice and clean and shiny, but I think the protective coating on them is now gone, and they might start to rust ? So a trip to Brafasco seems to be in the future as well, unless you guys can tell me differently.

ohh and the last picture is a Christmas gift, and not one of my pictures but a generic off of the net.....

So here are the parts, getting close to putting things back, slowly.....but I think I will hold off, a wee bit longer..........
