I guess nobody looked at my sig. I have an aftermarket head with a lot of compression, pipes, air filters, reeds, and +4 timing. When I said stock motor I meant only bolt ons. no porting or displacement increase. The reason i want to go to alcohol is more power like anybody else. I know that I need different carbs, but just was wondering what size and brand are the most common besides lectrons. Also what jets to get me close.
