Okay. . .I've searched and read all of the threads on the KX60 fork conversion and still have a few questions. This bike is my sons who weighs 80lbs and rides woods trails and will try racing hare scrambles this year. I've pieced together everything I need for the KX60 fork conversion and 275mm rear shock. Here are my questions. . . What rate springs are you guys running for your kids? I've read plenty regarding adult riders but how about the kids? Thinking I'll run 20w oil. What is the fork oil level for the KX60? What level are people running? Is 20w too thick? Thanks!
