I had this system fitted +K&N airfilter + wunderlich power controller + power snorkel to my 2006 12GSA, I liked it, very loud though.I will be fitting it to my 2008 GSA when it is run in.

Quoted from "Peter"

Thanks for the info. So hat was the difference when riding the beast?

Bike 2006 12GSA with spec as given on above post.



In my opinion, loud exhausts give the impreesion that you are going faster than with a quiter exhaust just because of the noise. The engine semed to rev easier and faster.Noticable pull at about 4000rpm, would hit the limiter very easily. I got it on a dyno and it showed 101 bhp at the rear wheel.

I will try and attach a graph of my 2006 12GSA (in red) and a newer model standard 2008 12GSA(in blue)

When I test drove the newer 2008 12GSA I couldn't see any power improvement , the salesman of course was telling me that I didn't drive it hard enough. I assure I did, but looking at the graph of the dyno my older 2006 12GSA was performing well.



When I sold my 2006 bike, I took off the extras off it and sold it as standard spec, I had to deliver it to the new owner which was about 200kms from me. There was a noticable drop in power at around the 4000rpm mark, and the engine didn't rev as freely.However the bike sounded lovely and quiet.

When I run in my new 2008 GSA (I only have it one week)I will fit the Akra , K&N, Power snorkel, iridium plugs and a Power Commander to it. I hope it will out perform my 2006 one. I feel that the gearbox is silky smooth, has it been modified / changed?

Fitted to my 2008 12GSA the Akro twin race system, k&n, power snorkell and a Power commander with a switch for changing the maps while driving. have 2 maps installed, one for a lean economy/Touring drive (102bhp /80ftlb torque at rear wheel )and one for a Sportier drive. (107bhp /85ftlb torque at rear wheel) I like it.
