Rear swingarm is 75mm longer than the original but I haven't lengthened the frame.
Swingarm, brakes and wheels all from a Honda CM200. Front end in this old photo is also a Honda CM200 but was only temporary. It now has Kawasaki EN250 forks and triple tree on it, with CM200 steering stem welded into lower tree because the Kawasaki stem didn't fit in the frame.
Air intakes don't suck nearly as hard as exhausts blow, so I hope it will work OK. It certainly starts and runs OK in the shed with this set-up but isn't ready for the real world yet.
