Put a new EBC clutch kit (frcition plates, steels and springs) in my WR450 04, soaked them in oil for 24 hours first. On the first ride out all seemed OK but once the going got sticky and the clutch use increased the clutch would not disengage even with the lever to the bars. Once the clutch use reduced on the quick sections had to adjust back as too tight. Spent all day adjusting at ther lever to compensate. Has anyone experienced similar? Any remedies? Did I do something wrong? One friction plate in the kit has a larger diameter (friction material about half as wide as the others) I put this one in last.
