It's a little high for most stock engines, but it all depends on the engineering of your engine. Many of the larger displacement engines tend to only be capable of lower RPM. Many of the smaller engines make up for their size by keeping everything light while engineering them for the higher speed.
A dirty spark plug can cause your lawn tractor engine to run at high RPM. A bad fuel filter can also cause this.
It depends how high you're talking about. If you mean revving all the way to the red line then yes this is bad for the engine. But the rpm shouldn't exceed 4000 rpm. If it is slightly below this then it is fine.
i would say yes because the 6300 has bad volume
Timing chain problem, excessive rpm, bad bearing.
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.
It is not good to rev any engine immediately after starting it. The lubrication system has not fully charged and oil has not reached all the parts immediately after startup. The oil is also thick and is not flowing as it will when the engine reaches full operating temperatures. So, the answer is Yes, that is a bad thing.
Peak torque on the c15 is between 1500-1700 rpm. Drag it down below 1400 under load and it starts lugging pretty bad
Using a Diesel fuel conditioner would be good for your engine and would not be bad at all.
It's a good engine, just bad to work on.
I/m expecting poor fuel mileage as well, cud knock sensor be bad? causing engine to choke at low RPM?
If the check engine light is flashing the engine is misfiring. Most likely a bad ignition coil.
Auto Zone will check engine codes for FREE. I thing you may have a bad coil park or plug.
