After looking for a year, I finally found a decent one. Not perfect but seems to have good bones.

1975 Suzuki GT750M ”Water Buffalo” - 3 cylinder, 2 stroke, liquid cooled. Brought it home today and went out for a quick ride. Very comfortable and decent power at 68-70hp. Had some idle issues so 4 hours after bringing it home I already started taking it apart. 😀 Cleaned and gapped points, static and dynamic timing. If you think the points on an XS are a pita, add another set for this bike.

Here are a bunch of pics. Looks great at 10ft but to my critical eye needs a bit of cosmetic work. This is basically a survivor bike and hasn’t undergone a complete restoration. First priority will be to get it running 100%.

As I start to learn about this bike, I have read posts on another forum of a cure for a poor idle. Apparently the coil voltage on these machines drops, sometimes below 10V due to crappy old wiring, connections, switches etc. A common mod is to put a relay in place between the coil and battery so the coils are fed a healthy 12+ volts. Any relevance for the XS?
 
Congrats on the new ride! Beautiful condition :cheers:
That relay idea is similar to Mailman's use of the relay to feed the Boyer Bransden ignition (which I did as per his suggestion)
With any luck you’ll be able to see it next month and take it for a spin!

That would be a lucky day indeed. :D
The fellow who owns the Suzuki shop near Nanaimo (where I bought my DR650) has one of those, I'm pretty sure, although nowhere close to the condition of your new one! He has at least 25 vintage Suzukis in his collection, even the rotary engine one.
 
There's nothing like a big 2 stroke road bike. When they hit the power band, it's a real rush, lol.

Low power to the coils is a common old bike issue. It can be on our 650s, but if you know the wiring, clean it all, all the connections and switches, then it doesn't become an issue. But, here's a write-up explaining how to easily test for it and how to fix it (with that relay install) .....

what camera are you using here? it's got much better than average impression of clarity

Thx 5T. The post I was reading recommended a continuous duty relay. Thoughts on the necessity of this?
 
Nice bike hard to find around here in that condition.
So far as the relay mod I have similar set up on my road bike. The key switch and kill switch in series power the relay coil.
Power via fuse from the battery powers the rest of the fuses.
I use normal Auto relays and also have a small control fuse to protect the relay control circuit.
 
What a great machine to start with. I ran a GT185 twin; and dad had a GT550 triple from this period. Always hankered for the GT750.
Would love one now, but in UK they are either show trailer queens or basket cases and too much money either way!
 
Yeah, probably $12 to $15 for a relay and a fuse holder. That's about the right weight for me to throw around solo, even at only 145 lbs. Love the styling of those years, and that front fender with stays. The new two stroke oil doesn't smoke, much better on plugs too. I would be at Walmart or Goodwill right now looking for a medium sized duffle to mount on that rack, reinforced with 1/4" plywood on the inside. Please give us a video with sound.
