Default End Cap?

Remember the dyno session a couple years ago (Lectron vs. TM). We couldn't figure out why a factory stock bike made 46hp when all others we tested were making 44hp. The factory bike had a stock #165 main in it and the outside temp was about 20 deg F. Sounds like she's a little fat from the factory to me.[img]i/expressions/face-icon-small-wink.gif[/img]

The Billet End Cap actually flows more air at low rpm which takes advantage of the factory cam timing. But flows too much air at high rpm which is why it wont make big power past 7500rpm.

Going against all logic is where I usually find the most HP.[img]i/expressions/face-icon-small-cool.gif[/img]
