Exhausts? Forget it. Why Suzuki didn't start a new production run is beyond me. EVERYBODY needs them. Most of the pipes that show up on fleabay are junk. Even if they look nice, chances are the baffle plates are loose and rattly (they were known for this). Fork tubes are obsolete as well. Your local salvage may be your best bet.
I hate to be a bring down, but these ARE the facts.

it could be the battery that is dying. These bikes use a "excited rotor" charging system, which means you need a good battery to get sufficient juice to excite the rotor, and only then will it start charging ....

if you don't know how old the battery is, it might be worth replacing it as these old lead-acid jobs are dirt cheap.

Even if the cnharging system is dead, you can get at least a couple of hours riding out of a fully charged battery (without lights)

Try forking by frank for the front fork tubes. He makes tubes for most any bike. Also, be sure you check the dealer on the pistons and other parts before you pay more for the same thing on ebay. And don't go to the dealer without a part number...most of the counter help will tell you they don't have parts for the bike or do a poor search without looking at cross ref numbers. For some reason, the dealers don't appreciate the fact that the bikes they are selling in 2008 have 30+ year old models still on the road...or close to it in your case. Also, don't just stick to ebay, do searches in google, go through links posted on web sites you find and eventually you can find just about anything...although it may be somewhere half way around the world. I have found many suppliers of hard to find parts this way....sorry haven't been looking for 550 parts.

By the way, what ever you think the resto will cost...add 25-50% more. And what evere time you think it will take to finish...add 4 times as long. Trust me on this one. You gotta love the bike you are restoring and like the process of restoring, otherwise you're better off picking up a bike ready for the road.

The book lists the pump shaft assy as being shared for all models after the 72s which has its own number.
The only thing i know of was Suzuki made pumps with pin drive impellers and then other ones with keyed drive so the difference was in the shaft itself.
However they got smart and made all later impellers with both key and pin slots since it seems they could not calculate which shaft style should be obsolete.
Has your dealer got pump shaft assemblies too????
Here you go Paul, these are the numbers you wanted, they might be good and not superceeded since your dealers stock is obviously old.
These are from a parts book thats dated up to 76 A models.
Pump shaft assy 17400-31830
Guard,bumper 72-73 94970-31000
Guard,bumper 74-77 94970-31200

Yea, i think I'll go for a runner. Keep what I have as a parts bike.
There was one on E bay last night in Ohio,went for $900,I was very tempted. It's just that,growing up in Ireland,I got a Christmas present of a suzuki history book, written by Jeff Clew, and it had a GT550 as a new model bike with a scantily clad chick draped over it, i wanted one. i was only 7yo or so. I had to settle for a GP100 when I was 16. I will keep looking. Thanks for the advice. If anyone knows of a runner for sale, let me know.

I'm in Warsaw,Indiana. Working with Scotty van Hawk,#27 in AMA Superstock. I came over from Ireland last year to work for Celtic racing and Chaz Davies. Loved the racing scene here so I had to come back for more. I was involved in road racing in Ireland before now,that's "Real" road racing, with walls and nasty things.
I miss my bikes, I have a Vfr/Rvf 400 hybred race bike,XT600 Tenere,CCM R30 motard and an R6 race bike,all in Ireland.
I want something different to ride here.

Here is a shot of the two cables - guess which one is the original? :lol:

After looking more closely, it looks as tho the ends are a bit different and this is what is stoppng it going into the oil pump properly.

So, is the new one just a poor copy/cheap knock-off or is it for a different model?

Yeah, when my bike's revs hit 5K you really have to tense up and hold on tight. Hard to believe a stocker only has about 60 hp. I don't know how much more HP expansions and porting adds, it just seems like much more. My XS1100 has 95 HP and it seems flat compared with this GT750.

I'm still looking for a grey (75) left frame cover if anyone has one, can trade for a good condition blue one.

The stockers were doing well to hit 60 regardless of what the factory said. BlueBoy has MAJOR engine mods and is hitting just under 80. Of course, it also still weighs 503 lbs!!! The power-to-weight ratio isn't impressive, but GT750s are still the most enjoyable two-strokes that I've ridden.

Some are more exciting (H2), and some handle better (RD), but overall the GT750s are the best two-strokes I own; stock or modified.

Yep, the GT750 certainly does pull on the other end of the handle bars!

The thing I like about them is they just run down the road, 75 for long distances constant throttle doesn't even phase them, just rummmrummmrummm as far as you want to go.

I think they are indisputably the best cruiser two stroke motorcycle on the market.

Of course the H's, RD's, smaller GT's, RZ's, RG's, S's, NS's, etc. are pretty cool too.

Hope you have good luck with it! Arne
