1988 Kawasaki mule more power needed!
 

Looking to get more power out of our sprint car pit mule. Original 88 mule modified with tool cart add ons. We need to be able to push start a sprint car. Don’t need a lot of top speed but need more low end. Any ideas ??? Compression is 118 and 116. Anybody ever do a snowmobile engine ??
