Yet another GT250 Cafe Build. I have been a lurker for a long time and just recently joined. I have always liked the cafe look and have built quite a lot of vintage racers and raced them in AHRMA and WERA. I have also done up some fun street bikes as well. The T500 has always been my base along with a few GT750s and the ocassional CB450 and CB350s thrown in.
I have always liked the smaller two-strokes and plan to race one in WERA Vintage this year. The bike I am now doing just might see the track this comming year. So here goes with what I am starting with. The bike as I got it pretty much is how you will see in the first pictures with the exception of the earlier bodywork from a T250. The GT is too boxy for me and I like the earlier bodywork better. All this is going to change again as I progress through this build.
The motor is ported with H1 heads added instead of the stock GT250 heads. I will modify the head even more with a better squish as I rebuild the motor and find out exactly what porting the PO did to it.
He added a set of what looks like RD chambers and made his own mounting spogots as the mounting to the cylinders is a screw on type instead of the normal bolt on type.
Carbs are stock and jetted, but with the aftermarket petcock there is too large of a fuel flow causing it to be too rich from start to nearly full throttle. The use of only screened velocity stacks were used to try and offset this I believe. This will have to be addressed in the build as I plan to use an RD type intake boot with large K&N filter installed.
Thanks Louie. I am 6'2" and 210lbs and this bike moves out smartly with me. People underestimate these little bikes and don't realize just how much fun they are.

I love these little guys.. I've built 2 of them. A 68' x6 and a 74' gt. I have a gt550 sitting in the corner of my shop too. It's unlikely that it will move anytime soon though. Love the sleeper look you've got going. All the critical gofast parts wrapped up in a sleepy little package.
Couple of the changes will be to add a 1968 Cobra tank in place of the T250 one. It is larger and with the chrome side panel with rubber knee pads. I'm thinking this will give it a more retro cafe look along with a yet to be purchased cafe seat.
The steel boxsection swinger will be replaced with the close replica of a Yamaha DG swinger. It will have the upgraded RD needle bearing kit installed.
I actually have a small hobbie business and specialize in Suzuki Two-strokes. It is "Sundial Moto Sports". I started it after my first race in Florida at West Palm Beach (Moroso Motorsports Park) I got the name for my small business cause the guys said I was so slow they needed a Sundial to get my lap times. Kinda stuck. Currently my site is down due to server changes and domain name issues but will be up soon. I have built some racers that have been riden by motojournalist Frank Melling if England and article publised in Classic Racer Magazine. I have been out of racing for a couple of years and plan to get back into it this coming year in WERA Vintage racing.

Here is a pic of another 68 Cobra I have done and rode for awhile. I have just traded it for a 94 BMW K75S. So many projects and so little time. The K75S is going to be my sport tourer. Though I actually put more mileage on my Vintage bikes than anything else. On my 73 GT750, living here in the Blue Ridge Mountains of Virgina, I go through two front tires to every rear. I scrub off speed going into the corners rather than hard braking before the corner.
One other unique thing is it has a homemade electronic ignition that works very well. The only unusual thing about the ignition is that "once-in-a-blue-moon" when you kick it over it will actually run backwards. I found this out quite by accident. I had started it up backed against the driveway berm, when I put it in gear it actually went backwards and almost up and over the berm before I could pull the clutch in. That was quite a wake up for sure.
Man there are a lot of GT250 builds going on now! Bought my two thinking no one would ever mod/customize them and get on this site and find a ton! (no pun intended) I love it! ;D Good luck with the build.
