OK, here's something rarely seen - it's a dyno run of my bike from back in 06 with the SAME zx cams and carbs the OP has posted about - This is a real chart, not just a verbal rendition of power. Where's the second powerband starting at 9000 rpm the OP is talking about?
Here's something I rarely do, but I'll say this - and y'all know me on this issue - talk is cheap, dozens of dyno runs isn't. Steve
You clocked up many miles on a Stock RX ?
I'm on my third and have something like 100,000 hard miles under my RX belt. and with a total of 2,000,000 Miles on bikes mainly Kawasaki GPZ's (From the Start my Despatch bikes: GS125, CB550, Ninja 600R, Ninja 500S, Ninja 750R, Ninja 600R, Ninja 1000R, KLR600, GSXR1100, BMW R80, Concours 1000, Ninja 1000R, Ninja 900R, GT750P3, GPZ1100dfi, GS850G). Ridden in ALL weathers plus all self maintained, fixed and repaired.
Figures and dyno charts I cannot deny have some meaning (but this is well known that dynos do not take into account ambient air temp and pressure, aerodynamics, air flow, weight, tarmac, weather and so on, they are a guide only giving the power and torque of a vehicle that is not actually moving).
Plus I should also point out that it has already been said you tried everything EXCEPT the RX CDi, which of course is mapped to make the best of the RX's Top End power. I couldn't give a rats arse about the loss of the midrange torque. I have 6 gears and I use them, I'm sure on a roll on all the other connies would leave me behind up to 100mph, Emabarassed? me? no I just change down and spin her up, but at the traffic light grand prix things MAY be different,
But there is no substitute for Experience.
Also I would like to point out that I am not known for 'bullshitting' I say it as it is or I don't bother (I always find it's best to get to know a person first before you make judgements about their charachter).
But hey what's the Argument? You show dyno graphs that state your bike has more power than x and you say that my bike would only achieve the sort of speeds I was speculating it should by falling out of an aircraft. Then I guess it must have fallen out of an aircraft on the German Autobahn, maybe that's where the Polizei were tailing me with thier radar in thier Audi RS6 (no contest, they could have blitzed me at any point, those RS's are seriously quick).
The mods that I have done HAVE produced the results that I expected them to. You're all welcome to fly over to Austria and try it out (but don't fall out of the plane, you might get stopped by the Polizei!), I have a Guesthouse here, so you'd even have a place to stay!
