1996 Buell S2 owned by Daniel Dunn

Standard bore 1200cc
NRHS Stage 2 Thunderstorm heads
SE .536 cams
Mikuni HSR42
Force exhaust system
SE Q module ignition system

Just got my bike back with dyno results and I'm feeling good about the mods. Then I check out another one of your dyno charts. You guys are killing me!

But it was the knowledge you shared along with lots of info from this forum that helped me make good choices. And you were right. I love the Mik! So you are forgiven.

I could actually pull about 3 more hp if I changed out the ignition to one that would allow me to go all the way to 7,000 rpms. The SE module starts cutting back at 6700 and it is really obvious on the dyno sheet. There still is more there on top. I was really surprised by this . To get over 100hp at the rear wheel on a trueu 1203 cc I did not think was possible until I started working for NRHS!! :) This bike is a hoot to ride!!!

Oh, we can make a lot more than this at 1200cc. This motor has very mild cams and compression. This is a long life pump gas street motor.

Dan, we should've done another sheet after the exhaust system mod, the bottom end reversion wouldn't have been so bad.

Thanks for the comments, handy, and glad to hear you like the Mikuni. They work good! Dan's a/f, after the reversion, was flat as a pancake. We didn't even touch the carb, that sheet above is right out of the box if I'm not mistaken.

Yes, the Mik 42 is right out of the box. No jet changes at all.
