Curiousity finally got the better of me today and I removed the secondary butterflys from the throttle bodies on my Gen2. I have to say I was expecting the worst, but was shocked and very happy with the results! The difference in throttle response was amazing! I'm not imagining it either; I ride wheelies, and now it is effortless in 1st and 2nd to bring it up! It feels like 3 teeth on the rear sprocket!
My 08 is mechanically stock too, both sprockets, exhaust, fuel map, ect., unless you count a K&N air filter, which I don't.
Now before anybody goes jumpin down my throat, sayin I lost horsepower, maybe so(2 or 3 if any, who cares), I never claimed the bike gained any, just a very noticeable increase in throttle response.
The theory behind the gain is that(someone correct me if I'm wrong)the secondary flaps make adjustments for B, and C mode. I only always use A mode, B, and C are pointless to me, and if it no longer runs smooth in those modes, I could care less, I didn't try them.
It was a 20 minute job too, remove the airbox, 2 phillips screws on each of the 4 flaps, remove...done.
And I'm not claiming it was my idea either, as said I'de been curious, I've read plenty of threads about it, with opinions on both sides. If you're interested in doing it, it's as quick to put back if you don't like it.
Like to wheelie? Then you'll love this!
