Thanks to a horrible 42 mile ride on ice, Thursday night we changed hyfax on my SRX 600 and a buddy's XCSP 700. His came off and went on ten times easier than mine. I tried all the tricks, and finally just removed the rear suspension when I got tired of nicking the rails. Why does Yamaha make these things so tight? Also, it looks like the Ripsaw windows would have to stretch a bit to fit the hyfax. I couldn't bring myself to cutting open the window on a brand new track. Anyway, no more bad riding conditions for me, and I'll start each season with new hyfax which I will continue to change with the suspension removed.
