hi
I have a knock in my valk engine, its not the timing belts or the adjustment idlers, tappets or exhaust which can all be heard in the sound file, its the dull knock.
with the clutch in or out makes no difference
it can be felt by holding the water pump but i've had the water pump out and its as smooth as,
can the oil pump and scavenge pump or chain drive make noise like a knock ?
any help is appreciated
the next question is has anyone had any experience in dismantling a valk engine down to the level of engine casing apart.
regards greg
