Hi all, I have a 2001 banshee with fmf fattys, power core2 silencer's' A boost bottle and a cut air box lid, I will be rideing at Big Bear About 6000ft above sea level. I need
some help with the jetting I have no idea what to run, Can anyone help me?

 

my friend was running 280's here at 5000 ft, he has pipes, reeds, no tors, and had mild head work done, dont know if that helps muchnbut thats all I got to say about that!!

 

That will help, the more reply's the better. I just need to get it in the ball park, it has stock jetting and it run's good @4000 ft, I hope I can get it close

 

I would say drop the main to the next smaller size. Or you can ride it there and see how it behaves. Good Luck.

HAVE FUN... ATV trips are great.

 

It looks like so far 260 - 280 on the main and 25 to 30 on the pilot is what people are telling me, hopefuly that will get me close I go the midle of next month so I have plenty of time, the real tricky part is getting her set up for
Pikes Peak next year I'm looking forward to that!!

 

Ahh, not really. Move the needle clip up 2 spaces and jet down 5-8% Should be just about right. I go to Colorado Every summer to ride. You should venture farther into the hills. Get a GPS and paper maps of the area.
