Dyno tuning My F2 5/8/11 -- Sheet and all!

Installed the street racer clutch kit on my bike. Neglected to take pictures of the whole process. It's a REALLY easy job, and in a matter of minutes it'll all be sorted out. Here's the only picture I took. I wish I had taken more of the process for others to learn from. It's really easy though:

Original (stock, IE: came with the bike) burnt up clutch plates!
Works good for sure. It's a little bit stiff, but I'm betting the springs will break in over time. The bike power on wheelies better, delviers power 100% better, and just feels great. This combined with the jetting changes has the bike feeling like a million bucks.
All that remains is the dyno tune tomorrow. WOOHOO! It's got a fresh clutch, I've adjusted the carbs to the best of my ability, and I had to change the oil for the fresh clutch, so it's premo right now for a run on the dyno!

The results are in!
I took my F2 out to the dyno day get together, and was feeling pretty good. The new clutch was amazing, the jetting felt crisp and strong, and everything felt pretty damn solid on the bike! I was hoping I'd come away with some good numbers today... and DID!

This was with a 1992 CBR 600 f2, stock headers, micron exhaust, Dyno Jet Stage 1 jet kit, K+N air filter, largest jets in the stage 1 kit, needles on the third clip with a spacer underneath (not the recommended 2nd clip with a spacer underneath per dynojet). Carbs were synched, and everything was good to go. Running premium gas (92 octane).
The feedback from the dyno guy was that it was about as close as was worth getting on these bikes. With a ton of tooling around with needle sizes and jets you could get a smidge more out of the bike, but really, nothing else worth bothering with. The power curve is smooth, the power delivery is strong, and the only oddity is just the standard 5k~ low spot, which is normal all the way through the F4i.
Speaking of which, I got a printout of the F2 side by side with a strong running F4i. Prepare for a comparison that should end the debate forever!
