ballpark jetting point

[xsinnerx]

i tried using the search function but it wont pull anything up for me. I need some help on my jetting, I'm at 1000 to 1100 feet above sea level, all my mods so far are tr-6 pipes, v-force 3 reeds, advanced timing at +4, barnett racing clutch, k&n air filter with pro flo adapter plate and the air box cut off. Right now on my stock carbs i'm running at 280 main and the needle at the 3rd position. I'm thinking i should be running a 340 main and the needle at the same it is now, does that sound about right? I will do a plug chop in the next day or two but i wanted to get an better idea of where i should be before i do a chop. thanks guys. oh yeah, forgot tors removed.

so...when you say the airbox is cut off, does that mean you're using the stock front piece (with the adapter) there's just no more sides to it?

 

Put 310s in there.... Normally pods take 330 to 340...but a friend of mine had a motor with the same thing you're talking about, he needed leaner jetting than that. 340 would definitely be a safe, Rich starting point....though.

 

Probably need 27.5 pilots...and if it's boggy in the midrange, lean the needle one clip (one spot toward the blunt end)...

I have 30 pilots and 340 mains, and the needle clip is lowered one slot from the middle second slot from the long pointed end)

 

My bike has the exact mods as you except my head is planed and my cylinders are ported I have perfect jetting right now. If I were you I would order a 27.5 and 30 pilots, as well as some jets starting at 300-340. You will probably settle with 310's or 320's.
