I have a 2006 Kawasaki 700 praire and i need help don't know if motor is blown or not when i first start it it smells really rich and smokey but later as warms up its smells like burning oil also the back cylinder is running at 120 psi and the front is running at 90 psi and when i look at the oil its a lil white what dose that mean ?

 

Sounds like ya lost a head gasket allowing the lack of psig and the coolant to mix with your oil from the front cylinder.

Do not run the prairie anymore and pull the heads for a check. You can check the bores at the same time just to see if there are any piston or wall scoring while in there.
