Below 4k rpm and below 40 mph my 97 z9 runs like its on 3 cylinders. I just got the bike. It has 15k on it. Above 40 mph it cleans up (ram air?).
I do not know if the bike has a jet kit. How can I tell? It has a full Micron exhaust. Can I tweek the carbs at all for this or is it just a characteristic of the bike?
Also, it has the dreaded kawasaki 2nd gear syndrome. It has a reverse shift pattern and to engage 2nd gear without sort of grinding it above oh say 6000 rpm I have to really slam it into 2nd (which is why I like the reverse pattern, lots easier on my foot!) if I do that it goes in without noise.. If I shift at low rpm its fine.. no problem.. I just changed the oil and did semi-synth 20w 50... would a lighter oil help with this?
