Can anyone tell me how to switch my carbs to Alky? I have 34mm Keihin carbs and was wanting to go to Alky, but I don't know what all is involved in converting them over. I'm currently running race gas and was told I could pick up .2seconds in the 300' sand drags if I would switch. What do you guys think? Alky is cheeper than race gas around here anyway.

ok on a set of keihin carbs once u put them on alky u cannot go back to race gas as the needle passages are not replaceable. u have to drill the needle passage out and change the needle to allow the use of bigger jets which u will always have to drill out. in my honest opinion just send the carbs to any respectable engine builder and u can get em done for like 100bucks or so and be sure to get powerjets installed in them as well. and alky for 14.50 a gallon if u payin that much then you are getttin raped badly my friend we pay 3.00 bucks a gallon for it here in sc and keep in mind its cheaper than race gas yes but u burn twice as much so it evens it self out. and a .144main is bigger than a 1/8inch, a .125main is a 1/8inch dead nuts almost and u should never have to run anything bigger thant a .125 unless your carbs are to small or ya pilot jetting and so on is off
