Thoughts on a Suzuki GS750 purchase

Manual
Since I am struggling with some charging system issues I have been doing some limited riding around my area. I came across a bike for sale in the boondocks and stopped to talk to the owner. The short of it is he has 1982 Suzuki GS750 with new tires, sprockets, seat, and lights. The bike hasn't been sitting and was a frequent rider until the owner had to do some jailtime.

Anywho, The starter is bad, it has no battery, and the carbs have been removed for about 3 months. The carb intake on the bike is currently sealed off with plastic/duct tape and the carbs themselves are sitting in a plastic Rubbermaid type box. The bike has 20,000 miles currently.

The owner seems in a bind and wants to sell it off for $600. I am about 100% certain if I showed up with $500 cash he wouldn't turn me away. I am no heavy hitter mechanic but does this seem like a decent deal? I would of course take a spare battery I have and make sure it runs first but I don't know squat all about Suzukis or their prices. Would appreciate any feedback.

It all depends on your area.  Where I am that bike would be advertised for $1000 and would probably go for $800.

I see a lot of guys where I am advertise bikes in boxes for more than $1000.

I would say if you could get it running, and it ran decent, it would be a good buy.  The key is if you can get it running...

As far as that year/model goes, it is a good, solid bike.  The key is whether it is in good running condition after the carbs are on, and a new battery is in place.  It is hard to say, since it is in pieces.  I am pretty rough as a 'mechanic' on bikes, so I would never buy such a bike, unless my professional mechanic could go with me, and tell me yea/nay.  Good luck.  Cheers!

I would offer $300.00 if it has a good title. Parts are hard to come by, for those bikes.

I ditto what tools said. My friend has the 83 GS750ES and he has a bit of a harder time finding parts for his than I do. They do have quite a bit more horsepower though...

heck, all you need then is a 750 yammie and 750 GPZ from that era, and you'd have all 4.

I used to work on one for a friend of mine before he sold it. They are a very solid fast bike. If it has good compression and not stuck I'd go for it, they are about bullet proof.

CONGRATS! I have an '80 GS750 myself. You are going to love the power that bike has with it's 4 valve TSCC head... and the Mikuni carbs are a piece of cake to work on and tune!
But just as a heads up, they were notorious for charging issues as well. Don't lug the engine around town, keep it over 3000 RPM. There is a simple wiring mod that helps with the issue.
 You can do a compression test with the carbs off, just will need the battery to crank it over... heck you can bypass the solenoid and jump right to the positive cable going to the starter.
 Just be sure to remove the tape off the intakes before hand.
  You'll want to check out www.theGSResources.com good bunch of guys there as well. When you get to the point of "grabbing a handfull of throttle", hold on. At about 6500 RPM she will hit the power band and climb right up to 10 grand before you know it.

Sorry I didn't grab any when I went to pay for it. I am going by to get the carbs and will snap some shots. He is storing it for me because I don't have space yet.

Hi,I've been riding my 82 gs1100e for years.1st there are different models.Your gs can have the 16 valve or the 8 valve motor.On the "E" you'll have the 16v motor.On the 1100 there is a 20 horse power difference!The frames are different too.Anything from the shaft drive "L" to the cruser "G" to the sport "E".Anyway,all fun bikes!All GS are known to have charging issues.lastly I would have the carbs jetted and leave it stock.With headers,pods ect the 1100 its tuff to get and stay spot on.

Slight correction there Mike, "G" was the shafties and "L" models were the cruisers.
On the 750 they went to the 4 valve head in 1980, the 79 and earlier were the 2 valve design.
Easy to tell the difference, the two valve head has round chrome end caps for the cam while the 4 valver had rectangle "trapizoid" shaped end caps.

 Man, I'd love to find one of the 1100 engines and do the 7/11 swap on my 750. There is a reason those and the KZ900 are still sought after by the drag racers.

I am building a 1230 out of a blown up 1150 for a friend. The pressed together crank is a real b@#$%. However I can't wait to test ride it. I told the guy "it will run like a 750 Honda"  "real good"

Little late on the thread but, figured I'd throw my two cents in anyway.
Those Gs's are nice solid rides for sure. My roommate just picked up a GS1100. I've been tinkering with it for him since he got it. Not a bad ride at all. I'll take my CB over it but, it's peppy.
It ain't a custom till you have customized it yourself.

Once you get that GS1100 running smooth, take it to a 3-mile stretch of straight roadway, with no traffic on it.  Run it up to 7,000 RPM, in 4th/5th gear, and make damn sure you are hanging on tightly!  That engine becomes possessed at 7k, and all hell breaks loose.  Just sayin'...  Oh, and a clean pair of underwear and pants, might be a good idea, too.

Take off the side cover and make sure the engine turns freely.
Assume nothing the owner says is truth.
Make sure the title is correct to the VIN on the frame.
$300 is what I would pay for a bike of uncertain mechanical condition (with clear title of course).
I was recently burned with a bike and locked up engine I didn't test, but got a clear title bike for $300 when the dude was asking $500.

My other bike is a Suzuki 750E, and it's a solid damn bike. Has only left me walking once.
I recommend a Dyna-S ignition to get rid of the ignitor.
