I have a Kawasaki ZZR400 1997 model. I have difficlty in starting the bike and when I do, it looses power in top gears. When I put Valve Ease in it moves like a Ninja, but thats only one tank. I have found myself having to tow my bike with another vechile to get it started and then the battery has been on charge. When the petrol pump is coneccted to the carborator it doesn't pump petrol, is that normal? The carborator sleeves (that thing that goes up and down in the carborator) dont move when you try to start it.The bike backfires sometimes when you try to start it. What the hecs wrong with the thing? Hope you had a good laught about my explanations, I did, I'm a Girl, LoL...... Your help will be appreciated.....
Hi and welcome to FixYa,
Initially, would suggest:
And the "carborator sleeves" will only slide up when there is sufficient vacuum (engine running) and the throttle is turned.
Good luck and Thank you for using FixYa. Happy Holidays.
Hi there i had the same problem wit my ZZR400 a few months ago.Ill sugjest u take it to a shop to get looked at.The problem with mine was that the valves pulled into the head.Ull have to get it sjimmed or get new valves put in or a new head.I put a new one on mine but the ZZR600s and now its running fine with a lot more power.

I have a problem with my 1997 ZZR 400. It won't start without engaging the choke. Once it starts it flats out at around 5000 RPM.
I also need to know how man turns out should I use for the air screw?
Just bought a zzr 400 1990 with only 6000 km on it so I did a service because was sluggish got new plugs oil oil filter fule filter and air filter when I start it it will only rev out to 2000rm I take the vacuum pipe off at the tank hold my finger on it until I feel it sucking out it back on and then most of the time it will rev out no bother but after 30 km drive it dies on me any help would be great full as I am fed up pushing it
