banshee_boy09 Posted July 3, 2007 Report Posted July 3, 2007 Hello, Im having problems with my banshee, it is bored .080 out with wiseco prolite pistons, cool head with 22cc domes, cpi inframe drag pipes, and stock reeds, wiseco hot rods crank. It has 240 main jets in it, which I think is too small isnt it? And Im not sure what the pilot is, I cant remember, but the lower the needle is, the worse it runs..so Ive got it raised all the way up right now, it still doesnt run right, but thats the best that Ive been able to get it. It doesnt really have any power, you have to be really revving it before it actually hauls ass, but if you start revving a gear out and then you let off and shift then it REALLY bogs it down as if you shifted up twice.... But Im thinking a bigger main and a pilot,..idk what do you guys think?? I really appreciate ANY advice. Thanks. Quote

peak-j Posted July 3, 2007 Report Posted July 3, 2007 I'd say your mains are too small, but you should do a plug chop and see what you really have there. Especially if it is on the last slot on the needle. Quote

banshee_boy09 Posted July 3, 2007 Author Report Posted July 3, 2007 If you have the clutch pulled in, it revs good, or not GREAT..but when I tell one of my friends that its not running right and then I rev it up then they are like " that sounds like its running fine"....( it sounds decent, but runs like crap.)

banshee_boy09 Posted July 4, 2007 Author Report Posted July 4, 2007 Ok, I bought some different jets... I went from a 240 main, 25 pilot, needles raised as high as they can be..to a 320 main, 37.5 pilot, and I left the needle raised all the way, So, the first start up and everthing it ran fine, or better than before, but loads up pretty bad before it really starts revving so I dropped the needle 2 notches and it ran better in some places..but it kinda cuts out now at lower rpms and still hesitates and stuff before it really starts pulling..thanks for any advice.

peak-j Posted July 5, 2007 Report Posted July 5, 2007 I hope you mean 27.5 pilots, not 37.5. I think you'd be fine with the stock 25 pilots, did you do the plug chop yet? If not do one. I takes a little bit of time to mess with but it's worth it. I think I went through about 12 plugs before I was happy with mine. Also, sychronize the carbs. I know a lot of people don't believe in the sync. tool, but I have one and it is a lot easier to get the carbs. right. It also makes a lot of difference in the low end I think. I was off one number on the guage and my lowend kinda sucked I thought. I sychronized the carbs one more time and got it right on and it made a difference. Just my .02 Quote

Just my .02 Well I got a temperature gun..and my left cylinder is running about 16-23 degrees F hotter than the right one...and the right one smokes ALOT ....maybe the right crankshaft seal ??? I have NO air leaks. Im running 32.5 pilots now.. Thanks. Quote
peak-j Posted July 13, 2007 Report Posted July 13, 2007 I know every 4 wheeler is different, but look at my mods and I'm still running the stock 25 pilots. I think your pilot is still a little big. Also what is your compression and elevation? As for the smoking, are you air screws turned out the same? Mine did that when I first got it and it was a dirty carb. Quote
