What would it take to convert a Honda CT90 to propane?

Post by sgtlethargic »

Is there a mixer small enough for a 90 cc engine? They're air-cooled, so what about a regulator (Is that what they're called?)? Ignition timing?

Thanks

There are mixers for very small engines. You don't say what this is used for but the Honda CT is only 7HP so I presume it is a generator or similar application. You don't say where you are but in the USA there are at least 2 or 3 companies that probably have a venturii style mixer for that engine. The engine would operate off vapour so tank size would be fairly important but in reality it would probably operate off a 20LB BBQ tank without any issues.

I think sgtlethargic has CT90 motorcycle and I have my doubts that a 20lb cylinder would be the ideal tank in this application. A 5# or 10# DOT might be a better option.

I've seen some examples on the internet (can't recall where right now) where people have converted their bikes to propane and the tanks were much smaller - more like a 14.1 oz cylinder. Just checking now, I see that there are specific LPG tanks for motorcycles but these appear to be found elsewhere than North America.
