I was wondering if this is the norm. Before I had my stage 1 (Big Sucker, Big Radius & PCIII) I was getting approx. 49 miles per gallon. Now i am getting approx. 40 miles per gallon.

 

thats better than me. I have a road king, and before I got the fuel moto package deal, I was averaging about 39-42 mpg. I'm down to about 33-35 now. I know it's rich, I can smell it, but thats ok so far. I may lean the map out some. I'm really not to concerned, it's still better than my or my wifes trucks.

I know fuel moto maps for performance and I have had no performance issues, other than it's a big improvement.

 

power takes fuel...better to be a hair rich reliability wise

 

Mine went down but I have no clue what I was getting before or what I'm getting now. I can just tell that it's thirstier than before. If that means my bike is running richer and cooler and better, I'm fine with it. It beats my V8 pickup any day. I'll keep feeding it.

 

Roadwarrior, I see you have the Big radius, are you getting much popping on decel. I am getting alot of decel popping. When the dealer did the stage 1 they set it to a base map. The tech never took it for a test ride. I was told to bring it back when the reopen after a 2 week shut down for the holidays and they would look at it.

 

Cooler ambient temp....!!!

 

Yes, it'll run richer for the above stated reason, power takes juice. But much more important, they come from the factory to meet EPA Regs, causes them to run HOT being that leaned out. You'll be runnig mo'pow'r and cooler temp. Worth the loss in mileage. Just my .02

 

Mileage dropped about 5-6 mpg after i did stage 1

 

I get about 40 mpg out on the road. I've got an '07 RKC with a stage I.

 

My 99 ultra came with a stage 1 and I have no idea what it got before the change from stock.
If I ride fast I get 35+ mph, if I ride through twisties and slow, 40-45 mph, I've got up to 51 mpg.
If you're getting on it more to'feel the power' you're certainly not going to get the kind of milage you could. The kind of riding you do makes a big difference in your milage.
