Trying out a replacement topic because the Photobucket policy changes trashed my old topic.
My 1973 GT250 had bad crank seals & has moved on to a new owner. Also pulled my 1972 GT550 project bike out of storage.
We are doing cafe builds of both bikes. The GT250 is up first & here are the pics.

Working on the motor.
Painting the crankcase.
Test fitting a Hotwing Glass RR1 seat. Will use a 1972 T250 painted a nice blue.
Fun with cutting tools.
Removed the center stand brackets, detabbed the frame & made cuts for a future frame loop.

Motor will be all black except for carbs & polished case covers.
Ordered the Higgspeed chambers.
Have the K&N tapered pod filters with rubber end cap. (# R-1070 + the filter wrap)
Stock main jets are 112.5 & we are going up 10 to 122.5
Let me know if you experts think this isn’t enough.
Motor is mostly assembled & we are now polishing the case covers: Cafe-GT250-7 by jabcb, on Flickr

Its just about 8 weeks since we ordered the Higgspeed chambers.
Just ordered rearsets.
The K&N tapered pod filters didn’t work out, so we switched to the angled version.
Got a custom oil tank similar to the one member sbaugz has.
Frame is at the welder shop.

Did a spiffy job at polishing the engine covers & fork lowers. (We cheated & had forum member Sandman do the work.)
A few parts are at the painter.
The T500 rearsets are here — now need to figure out how to adapt them to the GT250.
Once we got that figured out, then the fame + wheels are off to the power coater.

Test fit of right-side T500 rearset with trial adapter bracket made out of paper.
Not quite as clean looking as left side — gap between bracket & adapter is filled by a nut + ~ 2 washers. Cafe-GT250-0213_rearset2 by jabcb, on Flickr

The left rearset attachment point is the stock mount for the muffler & passenger foot peg.
The right rearset attachment point is one of the 2 stock mounts for the driver foot peg.
We thought about the different options.
Went with a no-weld solution that allows us to reinstall the stock driver foot pegs.
Next step is to look at how the Higgspeed exhaust will affect this solution.
Then the drawings are off to the water-jet-cutter shop.

Interesting idea - hadn’t thought of that.
My final adapter drawings are at the water jet cutter shop. Now just need to order wire + some little odds & ends parts.
We’ve talked about going with a single piece design at some point down the road. Will keep your suggestion in mind.
This is my first foray into CAD software + digital machining.
Was pleasantly surprised at how easy it is.
Have two other items I’m working on: a bracket for a CL450 exhaust, and an underseat bracket to hold the battery + taillight on the GT250 cafe.
