They actually listed less hp with flatslides on the zx7r...

Click the full specs and it says the R model with flatslides put out 4 rw hp less than the std model on the performance bike dyno test.
The flatslides work great if you have a lot of other work done but won't do much for a stock motor..
btw, the J model was strangled by cams and detuned engine to meet what they thought was going to be a Euro HP limit of 100. That model had less HP than all the others and carbies won't fix that...
I understand how cams can limit hp, and timing, and carby tuning and such, but knowing a bit about mechanicals, what do you mean by detuned engine? The engine is only a crank with some rods and pistons and a head and valves, are you meaning detuning as in timing and mixture and jetting and such?
Serious question, just wanting some more info.
I know I probably need cams and carbs to get mine to have more go go but I can't be bothered at the moment, but research is research and info is info.
