Basket Case Project 1980 GS1000

Option 3 - UK, Japan and Europe "Big" 750/1100E tank

again fouls carb tops slightly

 

[Guest]

I'd add its the petcock that fouls the carbs - everything else fits 100% straight

Nice! Thanks for all the options man. I'm definitely leaning towards option 3. Larger fuel capacity won't hurt but I'll have to see if the petcock could be modified or maybe the top of the carbs. The ones on my GS already has a small nick in it thanks to the petcock so that might be something that's already been dealt with.

Thanks again for showing the different tank options! Big help for me for sure.

Yeah, I'll just say that so far, all in I'm out probably 7 grand, including bike. I'm certainly not going to ride the **** out of the GS getting knee down and scraping pegs. I've got a Ducati Monster 900 to hit the twisties on. The GS is more akin to a midlife crisis mobile. It's like those guys who spend Corvette money on Hondas, practical, no, but it's a goal and dream of mine.

I have considered dropping a Bandit 1200 motor in and get the frame braced but that's not high up on the list yet.

If I thought about how much this is going to cost me, I would have never started. That's why I didn't started digging into GS's till a bit ago. Hit a deer on My Tiger 1050. Was out of work for 6 months and being in a wheel chair for only 2 months of it changed my outlook on many things. My old GS race bike had sat in the corner for almost 30 years and I almost E-Bayed it. The new bikes do everything better except get me excited about even looking at it let alone throwing a leg over it. Older GS's is what I grew up on and that's what I like and want. I like bikes with a personality, that's why I cant sell my Speed Triple and I am almost done Mod-stocking a 03 ZRX1200R. Your bike is sweet as hell. We need to talk! My next one is a 1100ES

Thanks for understanding and sharing your own experience limeex2. Yeah, the value that modifying old bikes (or cars, or anything) holds kind of always supercedes logical reasoning for me. I've always loved most things 80s and I've always been on two wheels so a Suzuki GS1000 makes perfect sense (and because Kawasaki Z1s are astronomically rare and overpriced). Bikes make me happy, old school muscle bikes especially, and I'm OK with it not being the most practical of choices.

Life's too short to not indulge every now and then.

From my perspective there are few bikes that look as nice as a GS1000. Swapping out the OE tank with the OS model 750/1100 tank will really change the way it looks. I would stay with the OE tank. Just my opinion.

 

[BasketCase]

While I agree that the GS tank is great looking, I'm also partial to the GSX tank. I like the muscle-bike shape of it. I think it will fit in nicely with the overall theme of this bike. Plus I got it for a nice deal. If I ever end up fixing the GS tank, I'll eventually reconsider it.

While I agree that A GS1000 is a beautiful bike, one member posted a pic of one with tank of a 81 750/1100 tank that has the indents near the knee area. Looked VERY nice. I did'nt see the previous posts! I like tank option 2. I have a brown 78 like yours that's unmolested (for now) I have all the good GS1000s parts. trying to figure what direction to go with it

This had an 83 750 Petcock fitted to it from memory but I still needed to lift the back of the tank (took out the rubber top hat on the bolt & used some fuel line instead to move it up about 7-8mm) and grind a spare carb top a bit on the corner.

Don't know if it fits the tank but you probably want one of the low profile "prime with a screwdriver" petcocks fitted to the 80 GS550.

Tank without the emblem holes is a 1000S tank made for using decals.

I have 1 side panel (can't remember what side but I could look) and both emblems I could be persuaded to part with if necessary....

Oh & I got approx the same range as the stock 78 tank with this setup, maybe slightly less due to the angle (or maybe just the reserve tube was a different height, can't really remember).

Thanks salty_monk, the petcock I have on the stock tank has the screw-driver type knob. There's already a small gouge on the carb where the closer petcock screw touched it. This seems to be the lower profile petcock but it still perplexed me why the petcock would not sit well with the carb on the stock tank. Turns out, the carb might be a 1100 since the K&N pods I ordered specific to the 1000 did not fit (smaller) so I ended up ordering the 1100 pods and they fit perfect. The petcock also looked to be moved slightly on the tank as someone re-drilled the mount on the tank (badly). So maybe the original location caused even more contact between carb top and petcock?

Anyways, once the euro-spec GS/GSX tank comes we'll have to dry fit it to see where the problem areas are and adjust accordingly.


And I do have NOS GS1000E emblems (the gold ones) waiting for when the panels are resprayed.


BTW: does a GS750E tail section/rear light fit onto a GS1000 frame? I also like how the 750 side panels have their back section slanted to match with the frame spar instead of the square-ish 1000 sides. Just a curiosity as I like the up-curved 750 tail and the cleaner sides.

Thanks everyone for all the info and contributions, and even the differing opinions too. Lots of good info and help on here!

Small update: lower GSXR triple cleaned up for powdercoating.

 

[BasketCase]

Updates!

Updates!

So, it's been a few weeks, figured I'd keep this thread somewhat alive.

Parts came back from powder coating, including swingarm, wheels, triple crowns, cooler mount, and a few other misc items.

The engine covers were also hydro blasted and polished, new polished stainless steel bolt set installed, and engine emblems as well.

Also, just today, the exhaust has been welded on with the angles sorted.

Next up on the list of to-do is a RCD/Racefit quick-filler for the new GSX tank with a filler tower welded on. After that, there's only paint, reassembly, and wiring (from the new more compact switches) left.

Bike is coming along quite well and the finish line is somewhat in sight! Super stoked and yes, she's going to be stupid loud!

I think that angle of the muffler looks much better than the one from the first photo.
With the huge core in that baffle probably better for the rider as well. haha.

I feel obligated to step in and say that I am glad this bike is getting attention. Mine was originally red, however I painted it black and used the red pinstripes. It is bone stock, except for green Dyna coils and charging fixes, and has 40k on it. The motor has not been opened except for valve adjustments and electrical upgrades. It's a great bike. I am looking forward to seeing how yours turns out.

looks sweet as ................

particularly the exhaust and the whole thing gels very very well ........ sooooperb

 

[BasketCase]

Thanks for all the kind words gents. This bike is going to be pretty awesome and quite special!

As an aside, the GSX tank fits right in with the petcock nowhere near the carbs! Score!
