bansheeman1988 Posted January 6, 2008 Report Share Posted January 6, 2008 K to start off I got a stock bore banshee with procircuit pipes stock reeds and carbs, and foam filter in the airbox. All that jetted to 280 main with 25 stock pilots and air screw 2 turns out. Now I am adding a whole bunch of little mods now and need to know if i stand correct. What ill be adding is V force reeds, K&N proflow kit and modding the airbox by cutting the second plastic piece on the inside of the lid to allow the intake hole to flow freely, also adding Timing plate, advancing 4 degrees. Now from what i have read on the jetting faq page i need to add, 4 sizes for K&N, 1 for airbox mod, 1 for timing plate, 1 position leaner on needles for reeds and 1 size larger on the pilots and finally 1 size larger mains for it being around 20-30 degrees. Now with all this i calculated it to be 15 sizes larger on mains (350), 1 size larger on pilots (27.5), and Needle clip moved up (leaner). I just dont wanna buy the wrong size jets and blow it up. Im thinkin of getting a range from 320-360 and the two sizes larger pilots to experiment with. Lemme know what ya think and thanks in advance!!!!!

black sunshine Posted January 6, 2008 Report Share Posted January 6, 2008 Does't sound bad, just start with your largest main and do a plug chop to find out for sure. Quote Link to comment Share on other sites More sharing options...

TJ10 Posted January 7, 2008 Report Share Posted January 7, 2008 I run the pro flow kit with no lid and 320 mains and thats a little rich so I think you'd be safe starting with 330 or 340 mains. I also run stock pilots but you could try 27.5 if you're not comfortable with 25's. The 30's would be way too fat IMO. Quote Link to comment Share on other sites More sharing options...
