I bought some forks off an '06 YZ450 and am working on them tonight to check them out, change the oils, and re-spring them. I have Race Tech .50 kg/mm springs in my WR forks that I put in about 9 months/30-ish hours ago, and my original thought was to put the stock springs back in the WR forks and throw the .50s into the YZ forks. Then just as I started working, I thought about the springs that are already in the YZ forks - is there any way to determine what rate they are? I only ask because although it does not appear that the forks have been apart before (based on the lack of tool marks anywhere on them), somebody did put some Enzo Racing KYB stickers on them and that got me wondering.
I know factory shock springs usually have a paint mark on them to denote their rate, but not sure about fork springs. Could I tell by measuring or otherwise comparing them to the stock WR .46 (I believe) springs?
Thanks for any help. I will post what I find in a bit.
edit: quick trip to the Enzo website reveals that if they do set up forks, they use genuine KYB springs. Not that I think these forks have been worked necessarily, because anybody can put stickers on stuff, but just hoping to be able to ID what's in them if they have been worked.
