I have a 2017 CRF250l with under 500 miles on it. It's never been dumped other than a light fall in the trailer which broke the taillight. At under 200 miles the clutch started slipping after an hour of trail riding. We were not doing crazy riding or abusing it. I barely got it out of 2nd gear. I have rode bikes for nearly two decades. I want riding the clutch. I brought it to the dealer and they loosened the cable all the way until there were no threads showing. Now its slipping again. I really dont want to have to fight with Honda warranty since it's a clutch. Why would this happen at under 500 miles and what can I expect from Honda?!

Is the inner cable still tight?
Or is there now free play in the clutch lever?
What is it like as it goes into the clutch housing loose or tight?
Just trying to determine if the cable is the problem or it is internal.
