A 93 could go either way if produced late in the year as the 94 model line was designed corrected for 63mm suspension.
Regardless, I would not suggest putting an 80mm fork on your Yo.
With the increased axel to crown length your head angle will be reduced, slowing steering and increasing wheel flop...yucky mix for you happy trail rides.
hmmm.. my wicked is 93. how would i know if it's late in the year? yeah. i won't. i will have to ride another one and compare.
