I keep suspecting I might have an intake leak (slight wandering idle, occasional backfire on warm up, slightly slower return to idle) but keep second guessing myself.

Decided to shoot a 15 second video and see what the badweb thinks: http://vimeo.com/89810580

Note: I shot the video after 20 mins of riding and 3 min of idling.

Batt terms are as tight as I can reasonably get them.

I could take another video of a rev and a snap off the throttle, if that would be helpful.

Reason I have this question is not because my bike is running terribly. It's because I've ridden a nearly identical bike that has a better throttle response.

Longer story is that my step dad has a '99 X1 in Oregon (I'm on east coast) and whenever I'm visiting, back home, I have always noticed that his Buell is a little peppier and more responsive. Knowing what my bike is capable of, but never getting there, has driven me a little nuts. And for the record, I'm more reliable with maintenance and upkeep.

Don't get me wrong though – at the end of the day, "slightly less peppy" is still a hell of a lot of fun

Something easy to try:

Warm it up again and lower the idle speed to 950.

If that doesn't work for you, perhaps something is a little wrong.

Lot of things can contribute to the pep factor. Aside from the differences in the overall conditions of the bikes, the intake, exhaust, or fuel maps each can make a difference in butt feel.

@Natexlh1000 - Thanks, I'll try that.

@Kalali -The bikes are pretty similar in many respects. Both have forcewinder intakes, default race maps, his has stock can, mine has VH. One is 99 other is 02.
