I run between 2500 and 3000, maybe 3500 once in a while. I just did a Stage 1 with the Power Duals, Ness Big Sucker A/C, SEST and RCX-Haust slip ons. Haven't been any distance yet, so can't tell you the mileage. There's more power now and I know I'm gettin' on the throttle harder than before the mod., so I expect my mileage to decrease - but dang, I like that POWER!!

I get 45mpg pretty consistently. 2011 RKC Powercommander PC-V, Jackpot pro-touring mufflers, fuelmoto air cleaner, cat delete. It pretty much ran like crap when stock. The upgrades helped drive-ability tremendously.

[QUOTE=stupid_rope;10530694]hammer that puppy. too many people never see the fun side of 4,000.
I agree, I stretch mine where I can, could tell you about fuel mileage, just ride until it needs gas. Like the 103 though. Congrats on your bike.

The 103's like a higher RPM than do the 88's. The sweet spot of the power band is 2500-3000. I keep my RPM's generally in that range, but on flat terrain in 6th can cruise aroud 2200. I consistently get 35 city/42 Hwy. The powertrain on my '12 RGU is stock aside from slip ons.

I had a built 103 in the RG. Numbers were 108h/121t and I was getting about 43 on the open road. It seemed happy cruising at just under 3K but could do well over the 1 ton in a heart beat.

I run my 2012 SG from 2500 to 3200. These are not made to be lugged, they need the higher rpm's. I put slip-ons on and nothign to the motor and get 42-43 almost every fill up whether in town or cruising down the highway at 60 or on the interstate. I love the motor

I have a 2011 SG with Stage 1 download, V&H oval slip on's and High flow air. I run 91 octane and down shift around 2200 but no less than 2000, I like to run about 3200 rpm but up to 3500 on occasion i have hit 4k. I get 48 MPG and usually ride at 75-85 mph.
I did not see this type of MPG until after my 2k service, it hung around 35-38 until then.
Congrats on the new bike.
