As some of you already know the Raptor 660's have quite a bit of motor vibration.

The other day when I went to go adjust my valves I noticed all 4 bolts were broken on the upper motor mount bracket to the frame. It might be a good idea to check yours before they break or, even worse, crack your frame from the extra vibration and movement when they come loose.

If they are broke, it's not that hard of a task to extract them. They come out rather easy since only the heads of the bolts break off and the threads aren't tight.

Tools needed to removed the broken bolts

center punch

90 degree angle drill

easy-out tool

Here is what mine looked like.

We just had to do the same to one of our 660's and just like you it was when we were adjusting the valves. We noticed the one was broken so I ordered 4 new ones, we only replaced the broken one but wanted some spares.
