87sheerips Posted November 19, 2009 Report Share Posted November 19, 2009 Well, you have to get the carbs modified to run alcohol. Drilled down tubes and main jets.... Then you should be fine as long as you purge with gas after each time you ride. I have had no problems with tank leakage or seals in the carb, etc.. make sure you drill your gas cap vent to 1/8" and also run a pingel fuel valve for proper flow.

Nope, you will have to drill out one of your large main jets. You will probably be looking at a .120" main jet orifice, and whatever pilot jet you get to cooperate with your setup. I am unfamiliar with stock carbs, so this is where my advice stops and hopefully others will chime in LOL. I think you'd be better off buying some used 34PJs that are already converted to alky. Would be much more cost effective and useful. Quote Link to comment Share on other sites More sharing options...

TIA Yes, I ran stock carbs on my 7 when i first built it. Drill them out, cut half of the float off and put a powerjet on it. It will work for a low budget build.

camatv Posted November 20, 2009 Report Share Posted November 20, 2009 if you drill them you will have to get stock tubes to go back to gas.. Quote Link to comment Share on other sites More sharing options...
