The ATV AnswerMan helps a reader with a Yamaha Raptor 660 with clutch issues

How can I tell if my starter clutch is bad? That’s what one of our readers has asked the ATV AnswerMan about his Yamaha Raptor 660.

This is exactly what the reader asked the ATV AnswerMan, followed by his answer:

My starter clutch went completely out. My question is when it started to go out will there be a power loss of torque, or would that be a clutch going bad issue? Clutch still locks when in gear, but didn’t have any take off power and moved like someone was hand pushing it. Also is there an easy way to find out if starter clutch is bad or if I sheared the woodruff key, yes there was some metal in the case Cover but none in the oil.

Your starter clutch can be tested by trying to rotate it in both directions. It will turn one direction, and lock up the other direction. If your motor starts every time without problems, it's prolly good.

Your clutch slipping can be as easy as needing to be adjusted. Check the lever on the motor clutch case, You want about 1/18in free play. You'll need to adjust the cable and lever on the bars to get the free play. Your manual explains how.
