I had put the FCR kit on my bike and when we were dyno testing it we noticed that the stock K&N's just knocked off 5hp right from the start in almost any combo. I asked my friend about it which led to a big discussion of intakes, tuned lengths, bellmouths, velocity stacks etc. and in the end I commissioned him to make me a better design as I figured we could probably reclaim that hp with a true velocity stack for the FCR. We did and it actually worked better than we even expected with pretty huge midrange gains on two different bikes we tested. We played with various lengths etc. and if you want to see the whole thread you can see the results, the build up etc. in my KTM build thread over at ADV titled "950 refresh or Mission Creep
" but to save you the reading of 500 posts of me learning to weld stainless and building my exhaust you can skip ahead to post 492.
Basically we made this for my bike and it was such a massive improvement that he decided to start making them for other people who are putting FCR's on their KTM's and now he's looking for other applications: Ducati's, SV's and Triumphs. Lots of people put these carbs on and it's a shame that so much is left untapped. If someone on the board is local to NY/NJ they should get in touch with Chris and see about fitting a set to their bike. We have a dyno in the shop so we can do the testing and tuning.
I have a Rickman Triumph that I plan to cafe so I'm thinking of these for that project and maybe my BMW cafe bike as well. Anyway, I hope someone here can work out fitting a set. I'd like to see the results.
