The best thing you could do is to get it to a rolling road, it's the only way to get it right.

Here is the set up I had:

ZX9R C1 Engine
TTS Foam Sausage Filter
MK 4-2-1 Manifold
CAT + R1 Exhaust Can

Dynojet Stage 1 kit (138 Main Jets fitted
Main Air Jet Blocked)
Dynojet Needles installed on fourth groove from the top
Fuel Mixture Screw 2.5 turns out

I also drilled an extra hole out on the slides as per the Dynojet Instructions at http://www.dynojet.com/pdf/2185.pdf Though some say that this should only be done for bikes, due to the increased mass of the car, the acceleration is still slower and so the main needle does not need to lift as facst in a car compaired to a bike.

Hwoever rolling road is still the best way forwards, but this may be a good start.

I need to get mine to a rolling road, but it drives well at present with this set up.

Cheers

Ian

thanks chaps

its booked in for rolling road on Saturday, but wondered if there was anything I might need to take, didn't want to have abortive visit due to lack of bits, although I suppose they should have most common jets.

A good fella working on a rolling road should be able to drill out jets to suit.
