Herk I cant do the picture thing very well, so try to find a Triton a Norton featherbed frame with a triumph Bonny engine.I made the engine mounts myself for mine, or another hybrid I built a Tricati a 250cc ducati frame with a 500cc triumph engine.

The Venom was a kick start, 500cc one pot you needed a good leg and valve lifter otherwise you were in orbit, also the miller electrics were a bastard, the picture has brought it all back thank you!
