my clutch wont disengage this started when i had been riding for a few hours and it got real hot at that point i just asumed it was heat soak. went riding yesterday for around an hour and the cluch was a bit finicky but no real problem, then today i changed the oil in the tranny ,i used .65L of 10w-30, and then i took it up the block just to test it out and now my clutch has a very hard time disengaging and finding neutral, is this a problem with the cluch plates or is it due to the cable, bike only has about 10 hours of riding on it. thanks for the help
