I have a 2014 Mule 4010 with approximately 900 hours that I use most every day. After a couple of hundred hours, it didn’t idle very well and would often die when starting off. I read about cleaning the throttle body, and that helped for awhile. I change the oil every 100 hours, so my routine came to include removing and cleaning the throttle body every time. Then , I read about Seafoam fixing the problem. Started adding an ounce per gallon every time that I added fuel, and that has solved the problem for the last 300 hours, or so. No more throttle body cleaning!!!

 

I had a Porsche that I bought used with 20,000 miles cheaply, I found out why when on about the third fill-up, it began to lose power. I spent close to 4 grand on repairs, after 3 tanks same problem. And repeat. I finally had an old mechanic tell me to use Seafoam. Fixed it, been using it ever since, I buy it by the case! GREAT STUFF!

 

Kawasaki checked my Vin number, no recall for my unit. 2 area dealer would do nothing.
Problem was in the throttle body cross shaft.
I got tired of pulling my throttle body apart and cleaning/lubing the butterfly shaft. As time went on, it was shorter time between cleaning. Got to where it was less than 10 hrs between cleaning. I suppose I could have drilled out the shaft holes and fitted/installed some brass bushing, but decided to replace the throttle body with an updated version.
Warning! this part is very expensive.
