ZXR 400 dynojet problem
Hi guys.. I have a problem. I have installed DYNOJET Stage 1 on my bike as per the instructions. The main jet 96 and the needle on the two groove from the top, fuel composition for 2 turns, floats for 11mm. A motorcycle up to 7000rpm is screwed in by rotation, while already over 7000rpm the engine stops and does not screw in, shoots from the silencer. I set the needle to the last notch and a little better, but still this mid range has too much fuel in my opinion. What do you think about this? I don't know if it makes sense to change main jet 92, or just go back to the original needles.

Re: ZXR 400 dynojet problem
use the oem needle, the dynojet stainless steel kills the brass needle seat.
with aftermarket exhaust, air filter or stock, use 92 main jet. bike run lambda 0,9-0,95 i measured with LSU 4.9 o2 sensor.
