That actually seems like one of those extremely rare websites which are UNDERPLAYING the results of tuning a ZXR400!!!
An aftermarket exhaust and rebore will easily see you 80hp at the wheel, and a few other choice mods should get 90hp with little fuss.
I believe some of the racers on here were seeing 80hp+ without the rebore.
I think the full works (rebore, lightened cams, jetting, exhaust, port polish etc) without resorting to turbo's and nitrous, could result in 100hp.  If not, it would be damn close to it.

				so not that good a site then cos i was thinking he was a bit off. Cos micron say that there system gives 15HP and thats without a k&n and dynojet kit and a tune up

				i only wish it was possible to get 80+bhp from a zxr400 that easily jamz.. in my experience the figures (and techniques) on that site are pretty accurate.

true, but I personally wouldnt have either 

 There arent enough hours in the day as it is, and I want to ride my bike now not spend my time fixing it/building it in the garage
And I still dont like Hondas, and that includes honda engines. Suzuki wins every time - their fuel injection is spot on, and the gearbox is wonderful
