Thanks again. I feel more confident now. I'll try to install the jet kit this coming weekend. I'll let you know how it turns out.
Regarding the exhaust, I've decided to wait until next winter when I can't ride to send the exhaust to Kientech for the mod. However, if I happen to see an FMF Q4 at a good price in the meantime, I'll get that instead.
