Fourth Rear Wheel kit on 05 Mono Shock

[BigDog05]

When you install the 4th rear wheel kit from Yamaha, you have to modify the 2 small spacers in the kit. Take 2mm off each of the spacers or use one of the spacers that was on the sled and use one from the kit with the 2mm removed. If you don't it spreads the rear rails and the 2 inside wheels don't line up properly in the track.

Or you could order the new 05 wheel kit that just became available from Yamaha. Part number is SMA-WHEEL-KT-05. The new kit retails for $39.95 Sorry you had to go through the headache of trying to figure out why they wouldn't line up right and then have to modify stuff to make it work out.

Guess I got the old kit, I ordered it back in early September before I picked up the sled.
