240 mains are way too small. Dont run that motor any more.

You are not jetted corectly

Where are you located?

What kind of air filter set up? Is your air box lid on?

Elevation above sea level and temperature are big factors.

You should be around 280 to 300 main

google says your 465 above sea level.

Id say start with a 300 main, needles in stock position (middle clip)

air screws (2) turns out .

This is with k&n air filter and no lid on air box.

And do some searching around in the jetting exhaust forum. :thumbsup:

would turning them that way now with my 240's have any effect? or should i wait till i get the 280 -300s?

[Handyman]

get the 280 or the 300 main jets. You are running way too lean....once you get the new jets in you;ll notice a diference. Get a clymers manual for the banshee and it will aswer a lot of question ou have. Or you can do a search on here and get alot of info that the book won't tell you.

I have almost the same set up as you and im running 310 mains. Shee runs awsome

Those air screws have an effective range to 1/4 throttle. Do not confuse them with main jet adjustment. The air screws will have little to do with how your bike performs at WOT. Always start by tuning that main jet and work your way down. I agree that 280-300 will be in the ballpark.

k thanks to all of you who helped me... im a newb at this so thnx... but thats what would cause me to bog out in 5th and 6 th gear? wide open?

 

 

im pretty sure i should b outrunning those stock yfz's right? with this setup?

[Bansh-eman]

with that setup i was running 320 mains, 27.5 pilots, stock needle 3rd clip, air screw 2 turns out... that should get you in the ball park..

 

if you want to find where to begin modding that bike make sure you use the search botton before making a post, i promise you it has been covered like 100 times, you just have to look a little to fnd it.

 

p.s. change your name
