Banshee jetting questions

So basically I need some input on what mains and pilot jets you guys think I should be running with my mods. My elevation is about 800-1000 ft, I mostly ride in the summer where the temp is about 60-75 degrees Fahrenheit. Mix my gas 32:1 AMSOIL. Just to add I would like to be on the slightly richer side.

My mods are...

Vitos superstock pistons

K&N air filter

FMF Fattys, and fmf silencers


Stock air box with lid, snorkel removed, few holes drilled in bottom of lid


Right now I have no clue what my jetting is and my shee does not seem to be jetted right, that's why I need some input, I was thinking about 290 for the main and 30 for the pilot not sure for clip position (in between rich and lean?), I don't know much about jetting so any help is appreciated, thanks!

280/27.5 should be close, is you remove the lid, something like 300/30

Thanks for the input! Any chance you know what the stock pilots are?

stock jetting is 200-230(depends on location and time it was sold) and 25 pilot.

So do you think that 290 for the mains and 30's for the pilots would be about right if I wanted to run a little rich? This is the kit I was thinking about getting.

I would just call up a dealer like fast racing and order some jets, would not buy the kit you link as ray is a fuck stick.
Call up kevin at FAST, tell him your mods, elevation and you are wanting some kits and he will get you a range.

Kevin is a stand up guy and will take the time to talk to you. You can get the jet sizes you are looking for at any decent sized atv shop for a couple bucks each. If you are careful you wont need bowl gaskets.
