While riding this past weekend I thought i felt something strange under acceleration from a stop. felt like it took a second for the clutch to let go completely. Thought it might be wheel spin since I was riding in the dirt. Then on the way home on the tarmac i was in 3rd gear and punched it and again it felt like the RPM's ran up but the speed did not increase quickly like it should. I have never had clutch issues on any other bike so forgive my lack of knowledge. What am I headed for? thanks for your input.
