Akrapovics fitting and map.

Power, noise, mapping, price, and the ever popular : "More power or just noise?"

Did you get them? Are they on yet? Enjoy mine, who did you order from?
I got the exhaust from Powersports Junkie. There were some issues with getting the y-pipe and mounting hardware but they got with Akropovic and made it happen. Picked up the box yesterday and installed them this morning. Disabled and plugged the SAS and I'm running the Akropovic map for now. I pulled the dbkillers before ever firing up the bike and man... it's loud, LOL. They may have to go back in.

Bike is running very smooth. I can get much lower in the RPMs now compared to stock and not get jerked to death or have to listen to the motor making death rattle sounds and it feels very smooth throughout the RPM range. However opening the throttle in high gear with rpms under 5 grand on the interstate makes for a lot of noise but not a lot of acceleration. I don't think it's actually accelerating slower, more that the proportion of noise to acceleration has changed. I will likely play with mapping a bit to see if I can clean it up. I'm working on making an arrangement for dyno time with my laptop and cable in hand so I can make some changes and check A/F ratios and as well as HP changes versus relying on the butt dyno.

You may find its fuelling too rich, my dyno run last week showed it running way too rich at 5% and 100% throttle openings, went from 113bhp on #9 map to 105bhp on akra map

Yup, rich it is, LOL. They probably run it on the rich side to account for variances between motors and not have a map that's too lean.

Did a bit over 300 miles today on backroads. I wanted to do a bit more but cut it short due to rain. Love the sound of the open exhausts when running a sporting pace but will HAVE to put the dbkillers in to keep the peace around home. I live in a VERY quiet rural setting and coming home at 1am from work with those open pipes will not make me popular with the couple of neighbors I share a road with.

Understand how quiet the country can be at night but the forest rats would hear you coming.

I have the EXACT same question. I was already running Akra's with akra map. I just installed a filter (ITG/with Rottweiler baseplate) and removed the SAS. The bike seems to run fine with the Akra map. If it's not smoking and it runs fine, do I need to download a new map?

You're introducing more air into the fuel mix so yeah I'd say it's important to run new maps. More air but same amount of fuel means it's running lean. Running lean is more fuel efficient but it's also hotter.

Go check out the Power commander 5 and Tune ECU map thread and grab a map that matches closest to your bike setup. There's plenty out there to choose from. Just remember if you're in an area where ethanol is in most of the gas pumps around you then you may need to richen up the fuel map by about 2% to compensate since most of those maps are from countries that don't mix ethanol with their fuel.

Thanks for the reply. I've been hearing that the Akra map runs too rich. So I was hoping that someone would say "Yeah, the Akra map is too rich unless you have an after market filter. Then it's close to perfect."

But I haven't heard anyone say that yet, so it sound like I'll need to download one of Kev's maps.

Another thing I haven't heard is "You can use the Akra map with Akra's and Rottweiler, just richen the Akra map 5% for all values (or above 2k rpm), or something like that. So I guess that's not a good option either.
