I'm not. The SSS fork on YZ's is an MX setup, and they take a bit more than the usual shim shuffle to get them to work well in an intense off-road environment. A lot of tuners aren't really tuned in to the differences that well, with as much focus as there is on MX in the dirt bike world in general. Can be done, though. I'm looking forward to seeing what the factory has done with them on the '12 WR. I had my Showa guy work on the KYB's. I'm gonna take them to a more experienced KYB guy next.
