If I read one more post about some ones tourer going 40-45 mpg. I swear I will go postal. So, you if see on the news where a Harley rider in Waco has killed more people than he has bullets. That will be me. ARGH!

Well here's the post you wanted, I get between 40-45 mpg with my PC-V, jackpots, SE A/C, riding solo all the time. Glad I live here in Ohio but, you people in Texas better watch out.

So as not to hijack the thread too much, glad to hear of good comments on the PCV. I am going to pull that trigger soon, thinking with the AT.
I wonder however why many riders check the MPG? Is it to get a sense if running too lean or too rich? My memory of when I fill, how much, how far puts me about mid-30's MPG but in reality I have no idea!

20,000 $ on the bike and someone cant live with 5 mpg dropp? i lost about 3 mpg (this is with the perfomance map) they also have a mpg map but it will run a tad hotter,also i think the 3 mpg dropp is due mostly because my wrist is much happier with the way the bike runs.

There are two sides to every story. Before my PCV install my bike was getting 38 mpg. After, it dropped to 30 mpg. I am on the 3rd map. 34 mpg and performance is about back to where it was before PCV. I am about ready to take the PCV off and go back with the Stage 1 download that is in there. Nothing exoctic. 2007 Ultra, Arlen Ness Big Sucker and SE slipons. PCV came from FuelMoto.

Performance and mileage usually don't go together that well. It always amuses me when people install a PC or something like it, then complain about the mileage. Does your scooter have more mid range scoot? If the answer to that question is yes, your mileage has probably suffered somewhat. With me, I find I'm a little more aggressive with the throttle, something else that hurts mileage. The mid range has improved, along with top end. The bike runs 20-30 degrees cooler oil temperature. Although my 2009 RK Standard has throttle management which drops a cylinder at 279 degrees when at idle, and I live in the south (Mobile, AL) it has never activated since I installed a PCV. The highest oil temperature I have seen since installation is 260 degrees. I, for one, I'm satisfied with what I have gained. Yes I have lost some mileage, high nows days are in the 42 mpg range, with lows around 34 mpg when I'm digging the spurs in. It is a bone stock 96 motor with a Screaming Eagle AC, and Rush slip ons. It has the standard PC fuel map installed that matches those components.

Maximum performance comes when you set AFR's to 12.8-13.2:1 at throttle positions above 80%, and if you operate in this range often your mileage will not be good. In the cruise range AFR's are normally set leaner, from 13.8-14.7:1 depending on your priorities--richer for better cooling and throttle response, leaner for better mileage. There's a compromise in there and that will vary from rider to rider. I find that you can set AFR's to stock levels and reduce heat if you have an oil cooler installed, so I'm at 14.5-14.6 in the cruise range (AT mode), get good mileage on the highway (usually 44-50 depending on speed and conditions), and oil temperatures never exceed 205° while moving, occasionally as high as 230° in heavy traffic.
If you lean your cruise range and keep your wrist out of the throttle you can keep mileage near stock levels, thus having your cake and eating it too. A big advantage of the PCV is the ability to add an on-off switch and toggle between two maps on the fly. Set up one for cooling and the other for mileage, and switch to the richer option when the going gets hot. Note that with AT the switch will toggle between AT (closed-loop) and non-AT (open-loop) modes, but that can achieve the same result.

So. I amuse you. I am glad you take amusement in my misfourtune. If I spend $312.00 on a product I at least expect it to give the same milage I was getting as stock and a tad (a little) more performance than stock. If not what is the use? I could use the drivablity from the PCV but not into high performance.
