How much knocking is OK?
Ok, I tend to be much more a rider than a wrencher. Mainly because I don't know much what the hell I'm doing and I don't have money to pay a mechanic. Having said that. I did check my valves at 12,000mi and It looked like one was a tad out of spec. I didn't adjust anything and figured I would get to it at 18,000mi. So, I'm at 18,600mi and a friend of mine was standing over my bike during idle and said, "that shouldn't sound like that, it's knocking a bit hard". I kind of thought so too when I listened. He said to first change the oil and see how she sounds. I'm gonna do that soon. Question is, how much harm is it to run around with the valves a bit out of whack? Can the engine handle it? I'm gonna get it checked/adjusted properly. I just haven't done it yet, but I don't want to be worrying about it while riding.
Thanks in advance.
