I recently had my engine rebuilt by ( utv engine builders/ also known as hy-tech ) out of Lake Havasu As. I received my engine from hy- tech on Dec the 10 the. Didn't get a chance toinstall it until the 14th and 15th. At a total of 4 hrs I was out riding, when the engine quits. After pulling the lines off the fuel pump and seeing there was no fuel being pumped out, I took a pump off an uncles ride. Tried the borrowed pump, and still nothing. Pulled rear plug out and found no compression. So now I have to pull the engine and send it back to utv engine builders again. I'm not happy with that at all.
