I have an '05 F7 carb and it feels really lean just off of idle up to about 5000-5500 RPM's. I have raised the needle as far as it will go and it is better, but still lean. Here's where I need the help, air screws are the one's closer to the top of the carb and the fuel screws are the one's further down correct? I want to increase the fuel flow, so I turn them counterclockwise to open it more, correct? If this does not work what would be my next move, install a larger pilot jet?

By the way, I know they are not lean from the factory, I have installed a tempaflow.

THANKS in advance for your help.

If that doesnt work try a smaller jet size or hower the tempa flow works. Also u shud check all of ur seels. I added 2 much Sea-Foam 2 the gas in my dirtbike and ended up ruining the gaskets.

Every sled is a little different but heres my set-up that works very well for my 05, Tempa-flow set at "dot" with 490 mains, 30 pilots, stock needle settings and fuel screw, air screw at 1 turn. Stock air screw setting is 1-1/2 turns out, mine runs like crap at idle and off idle with with 1-1/2 turns. Im not an expert but my sled rips all the way through the band and plug color and piston wash are very good/ to safe side.

bryonthefly,

THANKS[/b]

Ive never actually checked it, but I ride with other f7s of various years and set-ups and mine is as good or better than all the EFIs and way better than the other carbed f7 without Tempa-flow. Mine seems to get better mileage compared to the EFIs when we're takin it easy and about the same when we ride'em hard. Im headed up to Munising next week and I'll check the actual mileage cause now Im kind of curious also.
