endofitall9 Posted May 28, 2008 Report Share Posted May 28, 2008 everything with my motor is fine good comp and all. I'm just having problems starting it with my keihin 28mm pwks it doesnt matter if it hot or cold. If its cold it will start without choke on after about 5-8 kicks when its warm 2-4 kicks.. It doesnt load when it is idling it will idle all day long and you can go burp it and it will take right off just a lil hesitant, i spent this evening tinkering with it abit the airscrew is 1/2 turn out i moved the the needle up one spot and that got it to start just a tad easier..my question is should i go with a smaller pilot or a larger pilot..i searched a bit but got controversial answer as to which way the pilot needs to go.. keep in mind the airscrew is only 1/2 out and it doesnt load... 45 pilot MJN needle 2nd clip from bottom 150 main...

jbooker82 Posted May 28, 2008 Report Share Posted May 28, 2008 Step up to a 48 pilot and reset the air screws 2 turns out. If you have less than 1 turn out you need to step up to the next size pilot. If your over 2 turns out then you need to step down 1 size on the pilot.

BellicoseBanshee Posted May 30, 2008 Report Share Posted May 30, 2008 The Keihin Jetting BibleDRI Keihin Jetting Tech Sheet LINK This is a very useful link... :geek: I agree, 1/2 turn means larger pilot is needed. You will be happy with the carbs when the air screw is between 1 and 2 turns out... Quote Link to comment Share on other sites More sharing options...
