Was getting off the freeway after about 70 miles and heard a strange ..clicking sound coming from right about under me. Stopped and coasted in nuetral and ..click ..click and got slower as I got slower. Turned the motor off and coasted in nuetral and the same...click..click..click.It seems to be coming from the drive pulley area where the belt is(at the front).

So I ride 2 up home a 130 miles and get a trailer and take her home.This morning rolling off of the trailer...no clicking. Take it for a short ride...no clicking. What the click is going on ? Do not want to ride until figured out. Appreciate any help......Thanks.....
