erickson483 Posted May 9, 2014 Report Share Posted May 9, 2014 I just put a new billet intake on my quad a few days ago, and did a leakdown before I put it all together. I lost .5 psi over 10 minutes (starting at 6psi), I also put in a set of ported reed cages I had lying around to see if it would make any difference. I took her out for a spin and it is a little boggy in the needle range, and at idle after it's been running. Once the powerband kicks in, or at WOT she runs good but I am looking for advice on what to try or what's going on? Prior to taking it apart, I had no issues with jetting. I have SST pipes, stock carbs, no porting, air box lid on w/o snorkle, ported reed cages, UNI filter, 900ft elevation, 80 degrees. I need to do a plug chop but the weather is super shitty for the foreseeable future so it will be a little bit before I can do that. I realize you can't help too much without me doing a plug chop or two, but I can't stop thinking about it lol. Any insight for the mean time?

hp2000 Posted May 9, 2014 Report Share Posted May 9, 2014 Stock carbs. The slides are not on the correct side? Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
lowidenfast Posted May 9, 2014 Report Share Posted May 9, 2014 Have you synced the carbs since installing the intake and reeds? I'd start there and be sure that there are no leaks around the intake or reeds. Next step would be jetting. You can atleast idle it in the garage and play with the air screws to see if you can clean up the idle. I just installed VF4's and I actually had to move the clip up a notch on the needle jet to lean it out which was kind of opposite of what I was initially thinking when I installed them. BTW, what size pilot jet and main jet are you running and what position is your needle set jet on? ...I'm sure you've been told this before but I just recently experienced this for my self - if you ditch that air box, you will make much more power. Atleast remove the lid. I've only had my banshee for a few months and have gone through three different filter set-ups, finally settling on K&N pods w/ outwerwears straight off of the carbs and wow what a difference it made. I have similar bolt on mods as you and elevation and temp are close as well. Quote Link to comment Share on other sites More sharing options...
erickson483 Posted May 9, 2014 Author Report Share Posted May 9, 2014 27.5 pilot, 1.5 turns on the air screw, 280 main. Middle clip on needle. Slides are good, I don't mean to make it sound like it runs like garbage, just noticeablely different. I'll leakdown test again to verify the intake gaskets, then plug chop for the needle and main jet. Quote Link to comment Share on other sites More sharing options...
lowidenfast Posted May 9, 2014 Report Share Posted May 9, 2014 I have the same exact jetting as you currently but contemplating whether I should go up to 290 mains with the addition of the pod filters. I currently have a thread going about my jetting just trying to get others opinions before I make any more changes. Good luck and let us know what you find out. I'd like to know since our mods, elevation and jetting are so close Quote Link to comment Share on other sites More sharing options...
erickson483 Posted May 9, 2014 Author Report Share Posted May 9, 2014 I keep the lid on because I see a lot of water and mud on the trails I ride Quote Link to comment Share on other sites More sharing options...
lowidenfast Posted May 9, 2014 Report Share Posted May 9, 2014 I see. I recorded the jetting that worked with my air box so, as big of a PITA as it may be, I can always go back to it when I know it is going to be wet and muddy. Quote Link to comment Share on other sites More sharing options...
sleeper06 Posted May 10, 2014 Report Share Posted May 10, 2014 If your motor is tight 240-260 with lid on needle 4th clip leave pilot for now Quote Link to comment Share on other sites More sharing options...
erickson483 Posted May 17, 2014 Author Report Share Posted May 17, 2014 I finally did a couple plug chops. One WOT for the mains and one half throttle for the needles. What do you think? Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

erickson483 Posted May 19, 2014 Author Report Share Posted May 19, 2014 Anyone? I think the plugs look good, but would like your input Quote Link to comment Share on other sites More sharing options...
nastyracing Posted May 19, 2014 Report Share Posted May 19, 2014 Middle clip plug chops look good to me. Quote Link to comment Share on other sites More sharing options...
Strm Trpr Posted May 19, 2014 Report Share Posted May 19, 2014 your plug chops look great. you changed to a billet intake and ported stock reed cages. do you have your stock unaltered reed cages still? if so, put those back in, leakdown test it again, if it passes, then run it and report back.
