jonvia Posted May 1, 2012 Report Share Posted May 1, 2012 i am currently running vf3,pj34 carbs, t-5s billet one piece intakes and pod filters. when i start the banshee up and let it idle ill hit in on the throttle all the way and it starts "burpppinggg" but if you hit the throttle not all at once its fine? i am geared 15/40. could that make it bog down when im pulling up hills?

blubyyou Posted May 1, 2012 Report Share Posted May 1, 2012 What jets are you running currently? Quote Link to comment Share on other sites More sharing options...
decon Posted May 1, 2012 Report Share Posted May 1, 2012 I had the same problem with my bike. You either need to bump up the pilot or drop a clip on the needle, depending on your current jetting... Quote Link to comment Share on other sites More sharing options...
ticktock Posted May 2, 2012 Report Share Posted May 2, 2012 So you are stabbing the throttle and it's dieing? Ya, lotta air, lotta turbulence. Try backing your air screw in some. How many turns are you out? Bogging on long pulls, if your motor is not making the power it's prolly a few things, lean, rich. Hills are big, drop a front tooth? Motor needs more power!!

jonvia Posted May 3, 2012 Author Report Share Posted May 3, 2012 running vf3, billet intakes, pod filters, stock port, pj34 carbs 158 main, 48 piolet, and needle i dont know lol. gearing is 15/40 kinda tall, but it has the power to pull it. running t-5s as well. it sputters on top end like its hitting the rev limit and getting no power. slight bogs out of corners and 1/4 to 3/4 just putting around you have to give it a min to kick in.. one plug today is a brown color, kinda rich, and the other was lean? doesnt make sense to me.. running b8es plugs..

Check to make sure its there. Chances are, the screw fell out and so did the spring. Quote Link to comment Share on other sites More sharing options...

Chances are, the screw fell out and so did the spring. oh it is. i replaced one of my air screws and it came with a new spring lol. but it has more tension than the older air screw.. if i turn them both all of the way in, the new one can turn in one half of a more turn. mabey i need to replace both sides Quote Link to comment Share on other sites More sharing options...
decon Posted May 4, 2012 Report Share Posted May 4, 2012 Running those 34mm pj's on a stock port might be your problem all together, too much carb. If it's sputtering up top your getting too much fuel, throw a set of stock carbs on it until you get some port work done. Quote Link to comment Share on other sites More sharing options...
jonvia Posted May 6, 2012 Author Report Share Posted May 6, 2012 i have some dune port cylinders and a coolhead to send out. i just gotta save money lol. and the 15 front tooth is too much for my engine to pull i think haha Quote Link to comment Share on other sites More sharing options...
jonvia Posted May 6, 2012 Author Report Share Posted May 6, 2012 so, i synced my carbs, cleaned my filters, synced the idle circuit and turned the air screws all the way in and started over. they are about 2 or 2 and 3/4 turns out. i have a brown color plug. almost a tad dark cocoa color!! no more sputter on top either Quote Link to comment Share on other sites More sharing options...
