'Back in the day' somebody used to make the conversion parts (for the motor)...I hate to divert to another site, but you might find that wisdom at dragbike.com. I don't remember who it was who made those components as it's been quite a while since I ran in those circles.
Good luck, I'll be interested in watching the progress. BTW otakar, I'm impressed with your skills/knowledge/bravery etc... keep up the good work!
