How to make your own 4th Wheel Kit

1st: Purchase a extra rear wheel for your Yamaha.

2nd: You will need to take the existing middle spacer part#90387-2012c and remove the center portion of it for the new wheel you purchase. See illustration below for measurements.

3rd: install modified spacers and new wheel and you now have a 4th wheel to support your studded or un-studded track. See photo below for finished modification.

For the mono shock skid use:

8CR-47550-10 (wheel)
90387-2013L (spacer which is 4.379" long)
90387-20015 (spacer which is .972" long)
