78 GS1000 Rebuild ?'s

Howdy All,

So I am doing a "rebuild" of the old 1000 and I have a few ?'s for you folks:

1. My carbs need to be gone thru, is there any specific brand of rebuild kit that I should look for or avoid?

2. I am getting rid of the big fat Vetter fairing and going back to the stock style headligh (and a custom fairing yet to be made). Can I use a headlight and bucket/ears from a GS750, 1100 ect ect.? I know the ears need to match the fork tube diameter...I am more concerned about the wiring.

3. I would like to do some "modernization" while maintaining the integrity of "Japzilla" as I call her. Can somone recommend a nice aggressive/sporty tire that works on the stock mag style rims? Also, are their any more modern (Katana or GSX syle) rims that are a direct fit? I also want to get rid of the chrome front fender (sorry I hate it) and get something more modern-any recos?

4. Has anyone ever tried taking a seat pan from something else and custom fabbing a seat? I dont want to ruin the nice tour seat I have so I can use it for longer rides, but I want a more sleek look....maybe I would be better finding a used stock seat and fabbing from that?

5. Please suggest any get rich quick scams you may know of so that I may actually be able to fund this project.

Thanks a million everyone, and I will get some pics of Japzilla as she sits now and once I am finished.

General recommendation around here is to reuse all the metal parts - jets, etc. since they're better quality than the kits. Replace all the o-rings from http://www.cycleorings.com/, and get the top and bowl gaskets from the dealer or http://www.bikebandit.com. If you're careful you shouldn't need the rebuild kits.

The rebuild guides in the GS Resources garage can help. http://www.thegsresources.com/files/vm_carb_rebuild.pdf is for the early VM carbs like yours. http://www.thegsresources.com/gs_carbrebuild.htm is for the later CV carbs, but it has some useful tips.

Good luck
 
1. ptm nailed it ... avoid all of the kits. Just get the o-rings from cycleoring.com and clean the metal parts.

2. Wiring should not be a problem unless whoever put the fairing on butchered the wiring in the process.

3. I have never used them, but I see a lot of recommendations for Pirelli Sport Demons.

4. I would suggest finding a used seat and fabbing from that.

5. I have won several lotteries, according to all the emails I get. :shock:
I can't use all that money, so I will be glad to forward some of them your way. 8-[

Ditto on the orings. If you plan on putting on a 4-1 pipe and pods, buy a Dynojet jet kit, which is just a change of the main jet and the jet needle.

For the best fit, get the fork ears from a 78 or 79 GS1000. I've got the same bike and have some good pics of the wiring in the bucket. Let me know if you want them, or if I can help. Do you have a wiring diagram?

I have the Sport Demons on my Skunk and I love them. They were a big improvement. I'll be trying the Avons on my current project.

Pig Light: SOLD! Haha.

Thanks everyone, I appreciate all of the info. I will do what you suggested for the carbs and look at the tires you all mentioned.

As for the headlight: I have a guy locally who has a 78 GS750 light, bucket and ears he will sell me for $35. Seems like a good deal to me...any ideas on if this would work? Thanks!

It should work. The spacing between the forks on the 750 and 1000 are different, but not by much. If by chance it doesn't work, the bucket and light are worth the money. Let me know.... I might have a spare set of fork ears around some where.
 
Bruce, what kind of ears are on your 1000 in the picture? It looks as though the turn signals are mounted directly to the ears....and those turn signals are sweet too!

The ears are stock. The stock or aftermarket sigs mount to the ears. I found some sigs on ebay. They are made from aluminum, so I was able to strip the clearcoat and polish them. Here's some pics that might help. The pics show the old style sigs I had for a while.

Those are awesome! Eventually I would like to get something like those, but I want to wait until I "build" my fairing to make sure the lights clear the edges.

As an FYI, I scored the headlight, bucket, and ears (if I can use em) AND a ratty seat for $35. I don't care that the seat is ratty, I have a nice "tour" seat, but I want something I can customize, so this will work perfect.

I ordered the o-rings from the suggested cyclerings site. I am going to order the gaskets.

Another question, has anyone had success "coating" a gas tank? Mine has minimal rust inside, but I will have it all apart and thought about doing this or the nuts and bolts trick. Thoughts?
 
Use the POR-15 stuff. If you prep the tank right, it works great. Fix any dents first.
 
Great info. Will do. I will take and post some pics of my "before" and after and some along the way. The bike is in pretty decent shape for almost 30 years old, but yours is BEYOND nice Bruce. Kudos to a job well done man, I can see that you spent alot of money on Elbow Grease....haha.
 
The chrome fender can be painted. Just scuff it up some with 220 grit sandpaper and rattlecan it from there. You bike is black, right?


On the tank recoat, it's prep, prep some more, then coat. Take your time getting it ready

Overall, just about anything can be done to the 1000s and someone out there has done it.
 
Thanks Big T.

My bike is actually maroon. Yeah I think I might try painting the fender at least for a temporary solution. I suspect the bike may have been repainted, at least the tank anyway, and someone may have gotten maroon plastics to go with it.

I have been throwing around the idea of painting the bike since I will have it all apart. I may go with the classic black with white and red decals. OR baby blue with white...undecided.
