The engine was larger than i thought really..pics dont do it justice. With the full exhaust and the secondary clutch, it's going to take more room than I thought. But still easily done, so no problem there. With many hours searching on the internet today, I found a few specs on the engine. It's 338cc displacement, with 25bhp @ 5500 rpm. Magneto ignition, fan cooled. Its not the 40hp I was told(i thought that figure was a bit generous haha), but still that's plenty of power.
I'd really like to use round tube, but I haven't decided yet. Worst case i'll use all square. The bender i'm talking about is like this one:

You can buy a certain size die with roller for 150. I can build the frame of that bender quite easily out of 1" square stock. Go to HF for a cheap bottle jack, maybe 25 bucks. Downside to that style bender is only 90 degree bends max.
