What Size Jets Should I Run?

[BansheeTeam]

I Have a 2006 Yamaha Banshee with stock pipes and stock everything i just changed the handle bars and installed the YFZ450's brake light. Im soon gonna install black nerfbars thats why i painted the stock nerfs black. I installed a k&n air filter and was way too lean so i was wondering what size jets should i run i'm guessing a 220 maybe 240 because at 6th gear above quarter throttle it blogs as if its gonna die so i had to re-install the original filter until i get the jets. And would you recommend installing the 2 small air filters you know the ones that go to the carburetor. Then my mods would be filters, jets and thats it enough to beat other stock banshees. One more thing after installing all those before getting pro circuit 304 pipes would you guys think it would be okay if i install a pair or boysen's or V-Force reed valves.

 

Thanks for all you help guys appreciate it

are you running the airbox with out a lid ? with out the lid youd bump it up maybe 2 jet sizes and then check the plugs. doesnt the K&N filter come with jets and that, when bought for a banshee ?.

if you are running the airbox with no lid, you need to buy a proflow adapter (the lid helps seal the stock filter to the box)

 

if you run the 2 filters, you gota be careful that you dont run into deep puddles (theyll suck water).

 

if you want some reeds, a sponsor on here (chariot performance) does some sweet billet ones, they would go good on your bike and will be good for future mods.
