Start by checking the ignition components & sensors. Common issues, coils, modules, crank & cam sensors. Start by checking the basics first,eg wires plugs etc...
open or missing thermostat
If the Yukon engine has high rpm while driving, check the transmission for slippage, that will cause the engine to over rev. The overheating could be caused by the high rpms.
A dirty spark plug can cause your lawn tractor engine to run at high RPM. A bad fuel filter can also cause this.
The PCM limits the top speed of the vehicle by cutting back on the fuel if the engine RPM's are high enough to damage the engine
A Spoon engine is a high rpm race engine, and it is called a spoon engine because its made by Spoon.
Say when you pull up to stop light or sign and take off, engine boggs dwon until RPM's rev?
Put the engine into high RPM in neutral or park.
This will depend on what the "work" is. Example, if the vehicle is in neutral gear, on low rpm idling of course the engine is doing less work. But when the accelerator is pressed to rev up, then the engine is doing more work. Another example, cruising on a flat highway at high speed but engine's rpm is low when at top gear, hence engine is doing average work. But let the vehicle go up an incline and speed goes slow and the engine's rev goes high when on first gear, hence the engine is doing a lot of work.
A bad spark plug or spark plug wire can cause your Kawasaki engine to miss at high rpm's. A dirty fuel filter can also cause the engine to miss.
failure of head gasket :)
the rpm of a c240 engine is 2000rpm
