Banshee_Guy Posted April 21, 2006 Report Share Posted April 21, 2006 Im running Keihin 35mm carbs. The biggest main jet keihin has is 230. I run as low as -35 celcius and with a 420 vitos monoblock that will not be suficient! I was running 210 with a stock bore. ANyone know where to find the drill size charts to drill your own jets?

brock_fuzzy_69 Posted April 21, 2006 Report Share Posted April 21, 2006 i have seen this asked at times and guys said that they had found a chart but i have yet to ever see anything might need to run a powerjet on the carb if you cant get a big enough main jet i know that mikuni and keihin have different numbering systems mikuni is by the flow rate and keihin is either by the diameter of the hole i think Quote Link to comment Share on other sites More sharing options...
