Some New Dyno Results Don Guhl was at Adam's Performance earlier this week doing some ECU tuning on Gadson's bike. This bike is a hybrid. The only difference between the three runs is the ECU flash.
First some facts about Gadson's bike. It is reportedly an H2R motor (cams) with an H2R pipe but with an H2 snorkel and air filter. The runs were done with the air filter removed which added somewhere between 10-20 hp.
The code in Gadson's ECU is some kind of one off pre-production version and is likely not what will be in the delivered H2Rs. Don purchased a replacement H2 ECU over the counter from Kawasaki parts. All the Power Commander equipment was removed before the runs.
The first blue run was running the stock H2 bin with o2, PAIR and other items missing on Gadson's bike disabled. You can see the factory power restriction coming in at 10,500. Peak power was 237.9hp
The red run is the original bin as delivered with Gadson's bike except the rev limit was raised to 14,800. Peak power was 277hp
The green run is Gadson's bin with a custom fuel, ignition, and throttle maps. It peaked at 301.23 with a 40hp increase @14,500
These are all rear wheel power numbers.
We also tested a power mode patch I wrote. The stock H2 has only 2 power modes, Normal and Rain. The ECU however actually has Three sets of Fuel, Ignition, and Throttle maps; Normal, Rain and Unused. My patch makes the third set available so you can have Normal, Rain, and High Power. The mode is tied to the KTRC setting. The least intrusive KTRC 1, 2 and Off use the High Power, KTRC 3 uses Normal Power while Rain is still Rain.

One of those carbon fiber guys from back in the early zx-12 days needs to step up. Only problem is limited production, can you sell enough items to overcome development costs. Same thing applies to things like supercharger gearing or aftermarket impellers.

Can't speak for RR, but I would be interested in a repro of the H2R air intake. Mostly for the symetrical look of it.
