Jetting question

[fmfbanshee98]

Ok I have an aggresive trail port,boost bottle,+4 degree key,fmf fatties with turbine core 2 silencers,running br9es plugs, 300 main jet and stock 25 pilot jet. It is running at little shabby like when you first press the gas it kinda wants to bog down a little bit then it open up and runs good when you give it like 1/4 throttle. Anyone got any tips? Also what are the carb needles?

What kind of air filter setup are you running? Also, what size carbs do you have?

 

If you know who did the porting they could be of tremendous help to you in getting your banshee dialed in...main reason I say that is the porter knows what his setup likes best, and he can tell you about where you should be (if not there already) and what kind of power to expect at certain RPM ranges.

The port work was done by Tyson Racing. I am running dual k&n clamp ons with stock carbs.

Your problem is your pilots are too lean and the br9es plugs. Try a 27.5 pilot at 1.5 turns out on the airscrews and Br8es plugs.

Try raising your needles by lowering the clip on the needle. Fatties like the richer needle position. You have to pull the slides out of the carbs, then pull the spring back out of the slide, you'll see the gold clip inside, shake it out, disconnect the cable and you'll see 2 screws inside the slide, take them out and the needles will come out...also go back to B8ES plugs.

Ok so go back to the br8es plugs and move my needles up?I will try that and let you guys know. Thanx alot for the advice.
