ZXR 400 dynojet problem
Posted: Sun Oct 18, 2020 10:04 am
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.
