I'm trying to help a buddy out who's trying to get all his ducks in a row to add a little more power to his X1. I personally run the Forcewinder on mine but he was told that there were factory units that flowed more air and made more power. Any thoughts? FYI, he's puting a Force pipe on with a race ECM as the money comes it. What will he need to have done/reset after all the parts are on and will it even run at all when all the parts are on? Thanks for looking guys, Aaron | ||

I bought the milled aluminum oval set up from American Sport bike (p.n 5196)and am very satisfied with it. Honestly, not really much in the way of performance gains over gutting the factory airbox. The factory box was sufficient, but not well designed from a practical perspective. Looks good on paper, but hard to seal in the real world, too many curves to match. I had a poor gap and gutting the box leaves more chance for debris to enter- No good. One thing to note, you will notice an increase in noise from the airbox as the original design is that way to reduce sound to pass gov't standards. I have the race ECM, Buell race exhaust pipe, Supertrapp SS muffler and the American Sport Bike cleaner assy. Biggest improvement was the ECM exhaust change...sigficantly reduced pinging under WOT. I didn't order the tank accents from American Sport Bike as I like the look of the original box and how it finishes off the tank. I cut a spare airbox up to accomodate the new assy. I'll post some pics as soon as I can. | ||

"..an increase in noise from the airbox..." Do you notice that in street riding and at typical throttle openings? I have a AFT billet oval on my M2 and never notice any inlet tract noise at all with a helmet on. Of course I don't ride very aggressively. I occasionally take a short slower ride on the streets around my home without a helmet to listen for noises and can hear some inlet noise if I get on it to 1/2 throttle or so. Jack | ||

"I personally run the Forcewinder on mine but he was told that there were factory units that flowed more air and made more power. " I had the Pro Series CF "hamcan" race filter from the factory. I assume it did flow more than the Forcewinder it replaced because my mixture became leaner, but it sticks out so much, my knee destroyed the CF cover within one hour of riding time. I don't see how anyone with an inseam longer than 30" (mine is 34") could ride with one. An intact Forcewinder works better than a broken race filter, so I put it back on. The race filter was an utter (and expensive) disappointment for me. | ||

I have a 32-33" inseam and I bring my legs in tight I can just feel the edge of the AFT billet oval I have. You can see in in my profile. The AFT uses a K&N filter that is thinner than the race filter. It is only 1-1/2" wide. The backplate on that clears the frame tube by 1/16" and only sticks out about 2-1/8". So with a normal, legs relaxed, ride I never touch it. I found that AFT filter on eBay but can't find them for sale anywhere, I think they are a discontinued product that was made by a company called Atomized Fuel Technology. Nicely made, beautifully machined venturi, compact and light. Might not be the best in the world for air flow but I'll bet it is as least as good as the stock air box and it is a lot better looking.
