The last couple days i've heard a few popping noises when pressing on my clutch. I can feel these with my foot as well. I would press down and release as i can hear the popping everytime. Almost like if the clutch pedal arm needs to be lubed or something. I dont notice anything wrong with shifting or driving. Would do you think this could be? 75k miles currently on my em2. All maintance done by honda. Or maybe the slave cylinder is going out? Holla.
