  1. I am retired and am 65 yrs old.  Barely making a living and am having a problem with my 2002 Kawasaki Prairie 650 4x4.  It keeps breaking a valve and the end drops in the cylinder ruining my piston... I love to work on small engines and this is one headache for me and will accept all your comments on this as to helping me find what is causing this.

  3. I fixed my Kawasaki Prairie 650 by installing a new head assembly and lo and behold, it broke a valve again and destroyed the piston.  I am concerned that the cam are causing this only on the rear cylinder.  I need some guidance on this and would appreciate all of your thoughts on this.   Si.

  4. Hi, I am a new member. I just bought a 2002 Kawasaki 650 and when it was delivered to me I did not realize that it was running only on one cylinder. Man I was disappointed.. any way I purchased a new head for the valves were broke and it scored the top of the piston only and not the cylinder. This is the rear head that I am replacing and valves. I used a wire to hold the timing chain. Howere I noticed that the cam did not have the pre decompression items it had been removed and closed off on the timming cam. There is a arrow on the gear... Can anyone give me some info to time this.. I do not want to do it wrong and mess up the engine... I am also trying to make my 4x4 actuator manual since it was not working. I need a type of thumb control and I think a bike shift might do the trick on the handle bar with a cable down to the actuator and I am planning to drill in the gear and make a groove for the cable to turn the gear to engage the 4x4... any other ideas.
