I am running a CORE EXP on my 2009 YZ450F, last couple of riding it felt like it was out of adjustment (stalling) so I tried to adjust it tonight. Normally the recommended install gap (one turn plus 2 notches past the starting point) is perfect for my bike. Perfect 1/8" movement on the lever. However, this time, zero movement in the lever. So I followed the directions and went counter clockwise (unscrewed) the adjuster.....no change. I kept doing this till I was 7 notches looser that the recommended install gap. Still zero movement it the lever. The clutch works like a traditional clutch now so it is obviously too loose, so the lever should be moving excessively when the bike is revved.... yet zero movement. I have gone over the install video several times I can not find anything that I am doing wrong. I have also played with the clutch adjustment, zero effect. Anyone know why I would not be getting feedback on the lever when revving the bike? I am out of ideas.
