WTF

Went for the last ride of the year and my sled went to direct drive mode, NOT fun getting back since I was in Gaylord and staying in East Jordan.
Haven't had a chance to check anything out yet, but I did find a steal on a comet clutch on Ebay for $40 So I need a good setup fpr weights and spring. It's going on a 2000 Zr600efi with D&D pipe and can, running a 1 1/4. Mainly ditch banging and trails in da UP and lower.
Clutches? Drive shaft bearing?
Thanks in advance.
