I get 42-48 mpg, on 91 octane premium with no ethanol added. If I put in the 10% ethanol blend (sometimes it is unavoidable), my mileage drops by about 10%. The life of the bike so far (19k miles) mileage has averaged 43mpg. I ride probably 80% city commuting, so your mileage will vary based on how you ride.
I personally would not run the bike with slipons and an intake, without a fuel adder. I think at best, your ecm will attempt to adjust the fuel level back to the stock afr, which is already way too lean of a running condition (IMO). It is your bike,and you can do anything you want, but if your asking for advise, here'smy opinion. (Remember what you paid for it, nothing!!)
Call Jamie at FuelMoto, and order the PCV, with a two maps, one for highway operation (close to stock afr) and one for around town. Tell him exactly what you have for an intake and pipes, and then install a momentary switch (like the odometer reset switch, which with boot will cost you all of $15) and your all set to ride anyplace anytime. I have had slow response from FuelMoto by sending e-mails, so a call is the only relaible way to get a response IME.
The mileage will probably drop a bit, but that is because you'll enjoy the throttle response much more than you do now.
There are pictures in my gallery ofthe PCV installation which has worked flawlessly for me. Remember the dilectric grease on the electrical connections, since the PCV doesn't like water,and you will get it wet if you ever ride in the rain, or wash your bike.
Did you buy it for fuel mileage, or????????????
