I started up my 06 brute force today only to hear a very obvious rattle. At first i thought i didnt tighten up some bolts when i fixed my winch. I got closer and it definately sounds as though its coming from engine. It has 1200 miles and original clutch. Any suggestions?

 

I have an 05 Brute and mine has a sometimes loud vibration on high idle........it's the plastic on the front bumper.......could this be your rattle?

 

mine was the plow plate on the bottom that had loosened up .

 

If its a tapping sort of sound it could be the compression release sticking

 

I have '06 750 and I heard a rattle. It was the front engine mount. Bolt is under warranty, but the elongated ware in the engine block is not. Kawi will view these problems on a case-to-case basis.
The test is to put a bar under front of motor and see if there is any up and down movement. I had about a 1\2" play when I put pressure on bar.
Now there is no movement. When I change oil, I put power bar and socket on mount bolt and giver big time. Kawi will not warranty the next mount.
