Thought I'd post an update on my conversion.
It was a little more of a PITA than expected, especially having to make a spacer after ordering the Hyde spacers...I guess that's easier if you have a YZ spacers, which I was lucky that I did, since my previous 3 bikes were YZ's.
I have to say it was TOTALLY worth it!!! All day everyday.... I knew I always liked my YZ suspension (valved by Dicks Racing) but I was nervous going back in time to forks from 2007, but they are performing as good or better than my revalved KTM forks on my 2012 350XC. I now know for a certainty that I am a closed chamber fork guy...never had any OC's that worked worth a crap. My Sachs have a $600 revalve, which were 100 times better than stock, but they just aren't a versatile as these YZ forks.
Now I need to get the speedo mounted as I do miss that and I'm not going back.
FYI, I still have the hanger for 08-14 yz forks if anyone needs it, didn't realize the forks had changed and got the wrong one at first. It's brand new, POW106 $40 shipped.
