2008 Kawasaki Prairie 360 4x4 that won’t rev

[APExtreme1944]

Hello all, I have a Kawasaki that will idle perfect but won’t go over 10 mph.

Reset limp mode, checked belt sensor, it will go into 4 wheel drive but won’t rev up more than 2500 rpm’s. I have no lights blinking.

Ran perfect for months until I let it idle while cutting limbs on the trails. 
Had a new carb, air filter and gas, just won’t rev up.  
Assistance would be appreciated..

tks

Might pay to try a new spark plug before spending too much more money.

And can you describe what it actually does when it won't go over 2500.. does it start killing and then restarting the engine, or does it slowly fade out of power, does opening the throttle faster or slower, or more or less make any difference, does it do it in neutral or only in gears and under a load ?

And if you download a service manual and have a look it will tell you how to check for trouble codes.. They are something you should check for.

It sounds kind of like a fuel restriction, but because of your description of how it happened, im not sure, it didn't get too hot while idling did it, they are air cooled an need a good amount of air flow to keep cool, but if it just happened its not that hot so maybe not. You could replace the plug like Mech suggested and maybe check for proper fuel flow, and maybe do a compression test, while you have the plug out. Just grabbing at straws here, more information as to how it runs would be helpful.

I just reread and if it has a carb then it won't have trouble codes.. disregard that. 

If it's got a carb though then I don't think it's going to have any limp mode either..  Can you explain what you meant by resetting the limp mode please.

And, I just read in here that some kawasaki limit the revs if the park brake is engaged, which it will do by reading the brake light voltage..  Might pay to check the park brake switch and operation.
