01yamban Posted May 15, 2012 Report Share Posted May 15, 2012 Well it seems after all the problems I had with this 01banshee I have it right now put new spark plugs and got them at .30, turn the air screws out 2 an a half turns on each carburetor and it seems now to be good! it idols by itself it starts easy and when I give it full throttle in any gear it doesn't break up and it seems to be really good on low throttle too I'm not sure if I should keep adjusting the air' screw etc.. Or leave it alone? This is my set up. Fmf gold series with fattys, boost bottle , pro flow billet air intake, no lid on air box, tirs removed, sea leval "ish" 2.5 turns out on the are screws, 290 mains and 27.5 pilots. How's that sound?

vulvafan537240 Posted May 15, 2012 Report Share Posted May 15, 2012 2.5 turns on the air screw means that the pilot is too big. Should be around 1-1.5 turns. How does it run with the air screw turned in some? 27.5 sounds right. I can't imagine that you should have to go back down to the stock 25's.

DirtDiggler69 Posted May 15, 2012 Report Share Posted May 15, 2012 You may also want to ditch the boost bottle , they tend to crack intakes and that leads to air leaks and a rebuild . X2 on the pilot advice . Quote Link to comment Share on other sites More sharing options...
01yamban Posted May 15, 2012 Author Report Share Posted May 15, 2012 Thanks! So does sea leval mean bigger jets or smaller than somebody at a higher elevation? I'll try to turn them to 1.5 and see what happens Quote Link to comment Share on other sites More sharing options...
vulvafan537240 Posted May 15, 2012 Report Share Posted May 15, 2012 Bigger at sea level Quote Link to comment Share on other sites More sharing options...
01yamban Posted May 15, 2012 Author Report Share Posted May 15, 2012 Also it had 260 mains befor I did all this and it ran great till high rpm it stumbled but maybe the carbs wee just dirty? Quote Link to comment Share on other sites More sharing options...
vulvafan537240 Posted May 15, 2012 Report Share Posted May 15, 2012 260 is the size of stock mains and is too lean for pipes and no lid. 290 sounds close but no way to know for sure without a plug chop. Quote Link to comment Share on other sites More sharing options...
