I recently saw a post on another thread that talked about a mod to a KDX that I had not heard about before. Basically -- the mod (as described by the poster) states:
" One thing I do that I have not seen mentioned is I remove the spring that is part of the powervalve assembly and is located on the left side of the motor. I actually first noticed this when my dads bike suddenly seemed to run much better then mine. We later found that this is what had happened. He called Fredette and said that is actually how he runs his bikes."
Has anyone done this mod and, if so, what results? Any potential downside to such a mod -- with respect to the engine, etc.?
