mmajay Posted May 28, 2011 Report Share Posted May 28, 2011 Ok my motor is a 4mil with portwork and 33mmPWK's. I bought this thing running bad and today i swapped coil,stator and cdi trying to figure out why this thing will not run without sputtering on top. When i bought it it had 200 mains in it and i was wondering if 200 is to large?? I cant seem to get it running right to do an accurate plug read. I am at 215 mains now and that didnt help. Whats the lowest mains i should use to try and get this thing running right. It bogs if you hammer the throttle as well as stumbles at WOT. I pretty much think i have the electrical ruled out. Reeds are in great shape as well. Would 160 or 170 mains be to small? I also made sure the floats were ok. I guess what i am asking is what size mains should i be running? ^ hours of swapping parts today and still running like dog shit and i am desperate to get it right. I really think the previous owner could not get it right and sold it. Quote Link to comment Share on other sites More sharing options...
shee4speed Posted May 28, 2011 Report Share Posted May 28, 2011 sounds like the mains are way too big. Have you done a leakdown just to make sure everything is nice and tight first? Also do a comp. check. Whats your elevation? Quote Link to comment Share on other sites More sharing options...
mmajay Posted May 28, 2011 Author Report Share Posted May 28, 2011 Compression is fine @ 150 both sides, havent bought a leakdown tester for the banshee and i know you never know but i have had several 2 strokes and this really aint acting like a leak in my opinion. I really need to know where my mains need to be, although tomorrow i will lower dramatically and see if it makes a diferance. Quote Link to comment Share on other sites More sharing options...
Profilact Posted May 29, 2011 Report Share Posted May 29, 2011 Try yapping your plugs down to .020 Quote Link to comment Share on other sites More sharing options...
mmajay Posted May 29, 2011 Author Report Share Posted May 29, 2011 I dropped my main to a 160 and the top cleared out and runs mean but now i have an off idle bog that i assume the pilot is to fat as well,,jetting is a mo fo as well as expensive. I have to order some pilots and mains and pull carbs for the 15th time and see where i am at on pilots. Quote Link to comment Share on other sites More sharing options...
252wheelieking Posted May 29, 2011 Report Share Posted May 29, 2011 (edited) What up man? I just seen your post....The smallest main you should buy is a 158 & largest is a 165. (158,160,162,165). You will need them! Your pilot jet should be around a 48 & 50 or 52 is the largest. I had the same problem with my shee, off idle bog. Pull the choke up & tap the throttle lightly, if it clears up go 1 pilot jet size larger.Start with the 48 pilot 7 work your way up to the 52 pilot. Im pretty sure that you would dail in at 52 pilots & 158 mains. Every 20* temp change rejett your mains. The hotter it gets, the smaller the main jet. The colder it gets, the larger the main jet. Don't go less than a 158. A 158 is safe & you will not be to lean. I figured your jetting should be in this area because we have about the same set-up.
