I really hope this project isn't stalled permanently. I'm in the process of tearing my 74 TX apart and I'm noticing the same issues with mine as yours, so I know what to look for now! LOL. But seriously, did you ever finish her up?

No.... Unfortunately I haven't had a lot of free time since my son was born. Lol. I'm actually considering going to a different engine, even though I bought this beautiful '78 bottom end. I wrecked the '76 head, and I'm not sure if it's worth buying another one. Tri-maha maybe? 😉

I've decided to sell my Hyosung GT250R to finance the completion of this project. If anyone has an old two-stroke single over 350cc, or a complete but wrecked parallel twin over 450cc, I'd do trades, but I'm not holding my breath.

Well.... There hasn't been any progress in a while. The bike has been sitting in pieces in my grandma's garage following the breakup between my son's mother and I. With no time or money, or even a place to work, it's been put on the back burner.
That being said, I've got a line on something really unusual for tax time... A guy at work has a couple APU's sitting in his yard, with good engines. (In case you didn't know, APU stands for "auxiliary power unit". They're basically little diesel generators that also run the heat and AC on semis when they're parked up. Saves fuel and wear and tear. Since they don't have to have the main engine idling the whole time.)
The engines in question are 570cc liquid-cooled diesel parallel twins. I'm told they're rated at 28hp. Or the same as my Hyosung 250cc.
But that's without adding a turbo. Sounds like I might be doing something a little unorthodox....

Alright, here's a picture of an engine like the one I've procured. It's a 2TNV70 Yanmar, for those that are interested in the specifics. I chose this shot to showcase how narrow the motor actually is. Specs say 18 inches wide, 21 inches high, 16.9 inches from front to back. It should fit fairly snug in the TX frame. The reason things are taking me a awhile is I'm trying to figure out what sort of transmission I'm going to be able to use behind it. My first thought was to try and use an aftermarket Harley trans, like a Revtech 6 speed, but I hate Harley's enough (and the prices associated with them) to find that idea distasteful. Perhaps a Norton Commando unit, or something like it.

I've seen a couple of attempts to do a diesel conversion; usually lots of torque but not very responsive.

Good luck with it if you go ahead!
