Well my 400 is continuing to develop and we tried a new motor I got not long back and it's kicking out pretty much 80 bhp. Its running sp cams, 1208 rods, revving to 14,800, and +1 JE pistons. It's also got a RTD programmable ignition. We're gonna have a look at the valve timing cos I think it could be better, but to be honest on an all gear run on the dyno with the quickshifter it sounds awesome,

I believe the 1208 rods are those manufactured in the last two or three years of the ZXR400.

Looks like a pretty good dip at 12K where it should be rising. Did you have the ignition programed with known curves, such as the SP model?

its running flatslides, I swapped the engine back to the +0.5mm engine and we've been tinkering and its now reading 78.98 bhp, the +0.5mm motor has been in all year, we've just been trying to get the flatslides somewhere near for sometime
