Hey everyone,

I am going to put an aftermarket pipe on the bike in the near future; and was wondering about how my gas mileage will differ.

Has anyone actually increased their mpg's after the install of a new pipe?

For instance when we put a flowmaster system on my brothers f-150, he actually saw a slight increase. Can this happen to the XBR?

Thanks yall,
Alex

After installing a free flowing muffler on my Ulysses (of my own design) I noticed neither a decrease or increase in MPG.

After knob-dicking the fuel maps and O2 sensor input (making them richer?), via ECM Spy, I have seen a 2MPG increase, over the same 160 mile ride. Go figure how adding fuel could increase mileage...

I get 10% - 12% better since I fitted a Micron and a dyno tuned map to my 2007 XB12R.
The bikes with factory Race kits get good consumption on the club runs.

As good or better with just the SpecOps swapped in. Should be even better after tuning with ECMSpy.

I have a Special OPS, Race ECM, K&N filter on my 2005 XB9SX. I get anywhere from 45-50 mpg depending on wind, driving 75-80 mph down the highway.

Buell Race Kit on an 03 9Sl, 51 mpg on my last three tanks. 43-47 mpg before the race kit, but I was running the filter and race ecm.

I never worked the numbers before, but I usually get 65-66mpg on the highway with a Spec-Ops muffler. There was no change on the highway when I remapped the ECM and opened the airbox, a slight decrease around town though.

Xl1200r - How are you getting 65-66 mpg?!?! What crusing speed, RPM, when do you shift...I'm I have 219 less CC's than you and I get 10 mpg less! Please enlighten me? I would love to get in the 60's!

I would be amazed at 65-66 mpg as well! As he said though, "I have never worked the numbers before"

All this talk of mileage and the rising cost of gas caused me to figure out what I got with my bike, since I had never "worked the numbers before" The first time was when someone started a thread here and said running the engine above 4000 rpms would get you over 50 mpg in town. (must have been working for the oil companies, cuz all it got me was some high-torque in town riding!)On the highway, I do belive that statement though.

I have a 2004 XB12s with factory race kit installed. I will first admit that the sound of an aftermarket exhaust will make you want to hammer that gas often. So fuel efficiency was not what I expected when all that power is just waiting for you to let it free.

Everyone says don't blip the throttle as well, but nothing says blip the throttle like some chick giving you the evil eye because she is trying to make a cell phone call with her window open in the lane next to you! Don't even try to lie and say you have never blipped the throttle in that situation!

I was averaging high 30s, low 40 mpg around town with my heavy handed antics. It was not uncommon to get mid 40's on the Interstate at 80mph. I figured that was the sweet spot for this engine with the race kit.

Then when riding with my girlfriend on her bike, I experienced 50+ mpg doing the steady 60-65mph around the lakes. So I was able to get good mileage with the race kit. But never in the 60's.

It's cool to hear others notes though. I may cool down on the heavy hand in town, but I figure 40mpg is still better than my truck driving to work and back each day that it is sunny!

Keep the rubber down!

well its good to hear that people have actually seen an increase! that is just one more excuse to why I need an aftermarket pipe!

I will agree with Biff though, with the amazing sound and power waiting to be let loose, it will be hard to keep the riding and throttle steady to actually see the increase!

Thanks guys

On my Uly, it was about the same with both stock and then switching to the full race kit.

I more meant that I never ran numbers while the bike was totally stock, only after the the switch to the Spec-OPS muffler.

I don't check my MPG often, and I don't do much highway riding on top of that, but this is what I can tell you:

Last year, with the Spec OPS muffler and an otherwise stock bike only carrying me, I averaged 66 mpg on the tank I ran the numbers for. Riding was mostly at about 60mph on country roads - not a lot of hills or turns, and very little stop and go.

Earlier this year, on my down to MBV, the only tank I checked read 65 mpg. The bike had since had the ECM remapped, an open air box installed and a K&N air filter. This was averaging about the same speed, but with some more elevation change and stop and go than before, plus some flat out interstate mixed in (I can't remember specifically the roads - all I know is I filled up about 20 miles north of Charloettesville, VA... I did a lot of miles that day). And the bike was also carrying a weeks worth of clothes, riding and camping gear.

I'm generally in 5th gear by 50-52mph. I keep the revs down around 2300-2500 when cruising around town, and when on the interstate I'm usually around 75mph or so. When just riding normal, I shift at about 3000-3500 rpm. Spirited is 4000-4500. To go any higher means I'm hammering on the thing.

I'm not sure what the deal is with my driving habbits because I get better mileage in everything I own than is expected. My car is rated for 22 city/ 29 hwy, and I generally get 27 city/ 32 hwy (and have seen as high as 37.7 mpg over a 600 mile trip. I'm by no means a grandma when I drive, but I probably do a fair amount of short-shifting (which the Buell responds very well to).

2003 XB9R, 12,000 miles, Race kit, K&N, 12R air filter cover "swiss cheesed", TPS reset by dealer, 5280' elevation up to 14,000' (I live in Denver and carve the local canyons and mountain passes), I ride like I stole it, avg 85MPH on the highway - I always get 55 to 62 MPG.

I do +60 on long straight roads. XB9R with Drummer, K&N, race ECM. I do check, every tank. That's a very real number for those things. Those kinds of rides are not what I bought the bike for, but it happens. Even on spirited foothill rides, +40 is generally the rule.
