bama boy Posted May 12, 2009 Report Share Posted May 12, 2009 This has to be the biggest pain in the ass. I have got lots of info on here before on my jetting. I still have a bad bog when i shift. So from half to full throttle. Here is my mod list again .40 over boost bootle k&n filter no box 290 main 25 pilot needle 2nd clip from the blunt end. (if i put the needle in the middle it sputters really bad on the low end or just starting in 1st & 2nd gear) +4 timing key I think i am running lean. It runs really strong on low end and pulls hard. It also get hot really fast!!! Elevation is around 1800ft. Please help me out. Maybe I need to go up to 310 or 320 mains? Info would be appreciated otherwise i am just going to unload my banshee and get a yfz450. Thay may sound bad but this tuning is getting to be some bullshit.

black sunshine Posted May 12, 2009 Report Share Posted May 12, 2009 Do you have aftermarket pipes? What size sprockets are you running? Think your running lean, eh? Plug chop to prove this? Didn't think so :sad: You will face bigger challenges in life than tuning this Banshee! :sweat: Quote Link to comment Share on other sites More sharing options...
225GUY Posted May 12, 2009 Report Share Posted May 12, 2009 It bogs? But yet you say it runs really strong on bottom end and pulls hard? Interesting. Did you even do a plug chop? Mods? Quote Link to comment Share on other sites More sharing options...
Overboost Posted May 13, 2009 Report Share Posted May 13, 2009 a bog is usually a sign of being too rich. if it runs good down low and bogs up high, you are probably too rich on the mains with them few mods. try a 260 main. if your lean, it will more than likely pop, not bog. popping is a backfire that means it is lean, a bog means it has more gas than it can burn because it dont have the air to mix with it.

mopar1rules Posted May 13, 2009 Report Share Posted May 13, 2009 (edited) did you check for air leaks on your intake boots, around where your boost bottle plugs in? notorious for that to happen. boots can rip too. mine did. take off intake boots and check for cracks.

AKheathen Posted May 13, 2009 Report Share Posted May 13, 2009 does the elevation in you area get higher, or are you pretty much near the highest point by road? running pump? i wouldn't jump strait to 260, but only go 1 at a time. leaning your needle made an improvement, so that says to head that direction, and put the needle back in the middle.

GrMeyer Posted May 15, 2009 Report Share Posted May 15, 2009 Wow slow the role here...he needs to done one Jetting at a time here.... Start with WOT which is your main and work down from there. Just throwing mains in will change everything. So get your toppend fixed with plug chops and then the needle then the pilot and air screw. Here is a great site i always look back on to http://www.dfn.com/benkaren/jetfaq.html Quote Link to comment Share on other sites More sharing options...
lowbuckracing Posted May 15, 2009 Report Share Posted May 15, 2009 get rid of your timming key...Put a stock one on and see how it runs,those things take a shit...some guys have good luck with them..I would rather use the stock one and get an adjustable stator plate..If you need the key let me know and I will send it to you for free..+ fees and shipping..Lol Quote Link to comment Share on other sites More sharing options...
