Ive been noticing a knock in my 400 every now and then so today I decided to check the valves, they were loose, so I readjusted them and the knock was still there, So just to make sure I make them a little tighter, and the knock doesnt change. I talked to my mechanic and he said it might be a rod bearing going, but wouldnt that knock twice for every one compression stroke. But anyway I left it alone and came back tonight, started it up and it was silent, no knock, rode it around and got it warmed up and nothing. WTF?

How long did you ride the day it started to knock? Mine over heated once so I changed the oil. It starts to brek down when it gets to hot. But all the noises went away with the fresh oil.

thats funny because I just changed the oil right before I did the valves. I just noticed it sunday but I think it was gradual.
