more air = more fuel... but does that always = lower fuel mileage??   I hate to knock down the fuel mileages - only getting about 45 as it is.

Very good chance you will have to re-jet. The K&N flows a LOT more air thus requiring more fuel. You don't want to run too lean; you will spend too much of your riding season( and money) re-doing the valves and possibly deeper repairs..

I just ordered a K&N the other day, so should be getting it in soon.  I hope to not have to jet carb, but I guess we'll see.

Fellow 800 Drifter owners out there, I have a stock 2006 800 Drifter and would like to upgrade my intake filter, is it possable to use a K&N filter in my stock intake filter box? Would I see any gain in performance & gas milage with this simple upgrade? Would I need to do any adjustments to the carb. I would love any help with this. Thanks in advance.
