Well, I can say this jet kit made a monster difference. Feels way smoother, got rid of the bit of surging it had at neutral throttle. And then there is the top end.... wow. The old jet kit used to cause a problem above 9500 rpm, this now pulls friggin' hard all the way to redline. The idle is a little rough but it picks up smoothly from there. I'll wait to get the K&N next week and then do the rest of the tuneup. Thanks for the offer Wayne, that'd be cool.
