Hi Resmas,
Due to the really amazing blue sky and sunny weather in London today went for the first run, (up to Hemel Hemstead KTM dealer), since installing the new Motobox and ripping out the shitty, heavy, ugly airbox and SAS system.
First report is OMG what a difference! Smooth throttle below 3/4,000 rpm - I really noticed how much I'd developed the habit of feathering the clutch in 1st and 2nd, finger always on the lever in traffic. Now I don't have to do that. Also the sound is awesome! Induction similar to my old aircooled Ducati, pretty deafening at over 80mph - really loud at 100, can't really hear the exhaust - and that's with Akras with no baffles. But I'm not into touring so that's not a problem really, just makes the riding experience very raw - which is how I like it.
Can't comment on power gains, as it always feels bloody fast, but we will wait and see when I get a dyno run soon when it's custom mapped with the PC111.
Also, (but I believe that this is down to SAS removal), is that the overrun popping I've lived with for over two years is gone. I know that this divides opinion but for me this is better, I love the smooth bwooaaaar of overrun and can well do without the distracting backfire so for me this is great!
I have photographed the stages of work needed to instal the Motobox, take out the SAS and fit a PC111 and am putting it together into a downloadable document so that Aaron, at Motohooligan, can send it out to people like you. I'm compiling an introduction with all the benefits and pieces of advice that I've found searching through these threads including dyno maps, links to related threads and testimonials from happy Motobox customers. It seems that for such a fantastic bit of kit it shouldn't be that hard for new interested parties to find out about so I'm doing my good turn for 2010 and spreading the word. Should be finished soon but if you just want the pictures/instructions bit that's done and I could send it to you. Like all converts I just want people to see the light. It's worth it for the sound alone!
Don't think about it anymore, get one ordered!
