I bought a 2510 new, fan blade on heater slung a blade off, linkage was not adjusted correctly on 4 wheel drive, kept popping like it was going to breake somthing,rear diff. did not have oil in it. I had to buy it on my own. Speaking of oil, ever 12-15 hours crankcase oil has to be changed because gas is in it. I have drained out 3 qt. You know it only holds 11/2 qts. During the warranty period. me,the dealer,and kawasaki in CA. headquarters argued till time ran out. Still arguing. 4 years later. I've been to 3 dealers nobody knows nothing. And will not do anything. They tell me I have a freaky problem noone else has. I finally found this webb site. seems like some body is lying.After $10,500. they should have better engines, besides that you can't keep plugs from fouling tried everything.
