I need to dyno the MC28 to finnd out the power, but I was surprised at the difference, which was much more than I expected from reading the forum and checking all the various pages on the internet. The front comes up just rolling on the throttle at 9,000rpm. Also I meet a great deal of other NSRs at the track and I don't know if it's my imagination, but I'm sure I pull faster out of the corners ... maybe I'm just keeping it in the powerband better. Only a dyno can tell.

The suspension was overhauled but not modded. This year I'm putting an RS250 complete front end on it, steering damper, and going to magnesium wheels, plus getting the suspension measured, overhauled and set up by a racing suspension guru. I'm not aiming to be competitve. Haven't really lightened it, except it's got race bodywork/tank (read tatty), and all the lights, mirrors are removed.

To go fast, I don't need ever further-refined engine mod.s, I need tip top suspension/brakes, properly set up, and lots of training.

If I am tempted to get competitive, then I'll either go to the 600 class (might do some team racing on a CBR600RR this year), or GPmono, which is a relatively new class in Japan: RS125 frame with 4-stroke engine.
