i have a 04 zx636 and the valve train(i think) sounds like someone dumped marbles in it... tapping or knocking no sure what but its loud... just bought the bike in feb with 16k on it and got a receipt from a reputable local shop that said they put a manual cam tensioner on along with a 15k service... new ngk plugs, air filter, etc... ive done two oil changes and had to burp the oil filter both times to get the oil pres light out... my question is about the knocking/tapping/marbles... is this normal for a 636... or should i worry?
