My 2003 Kawasaki prairie 360 when u install the hose from the air box it will only idle u can not rev it up take the hose off and it runs fine

SOURCE: dies at idle

1. Carb jets may still be dirty or improperly sized.
2. The Cam and/or Cam journals are worn down and allowing some play in the timing.(Very common on the XR's)

SOURCE: Kawasaki ZZR 250. Engine hydrauliced after fuel

sounds like you blew a set of piston rings. instead of building compression in the cylinder its pressurizing your crank case forceing the oil out the breather into your air box

SOURCE: 2002 Kawasaki ZR-7S. wont rev up.

Check you main jets ccccccthey could need a good wiring through with needle wire cleaners or try running it without any air cleaner unit .If it runs well then could be an air filter problem.

SOURCE: Bike wont kick start or idle , it will coast

first drain the carby, then set your air mixture screw 2 turns out, from the fully turned in position. The starting proceedure is as follows, when the engine is COLD, turn on fuel, pull on the choke fully, and kick the engine over. DO NOT use any throttle, when the engine is cold, and the choke is on. Remember Choke on, NO throttle.
When warm, no choke, and a little throttle when kicking.

Battery voltage falls off radically with a drop in temperature. To really test a battery you need to apply a load to it and then check the voltage, but it has to be a considerable load in the region of about 50 amps. Try another battery or even a jump start at those low temperatures and see if it still will not start. If it starts, the battery is on its way out.
