Comments on: Ticking sound from CB550 engine, valve lash? http://www.mylittlemailbox.com/brass-mailbox/ticking-sound-from-cb550-engine-valve-lash/ Thu, 06 May 2010 16:25:10 +0000 hourly 1 http://wordpress.org/?v=3.2.1 By: guardrailjim http://www.mylittlemailbox.com/brass-mailbox/ticking-sound-from-cb550-engine-valve-lash/#comment-639 guardrailjim Wed, 17 Feb 2010 08:29:59 +0000 http://www.mylittlemailbox.com/brass-mailbox/ticking-sound-from-cb550-engine-valve-lash#comment-639 My crystal ball isn't working at the moment. Sorry, I just had to say that. Engine tear down and inspection is required. It would've helped knowing the mileage on the engine. A ticking noise is not normal, or common on that model. It could be valve lash as you suspected - a simple adjustment can rule that problem out if the adjustment doesn't make a difference. If the valve lash isn't the cause of the noise, the next possible reason would be a worn rocker arm and/or rocker arm shaft. Rocker arms and shafts ware out on bikes all the time - your bike is no different. The year of the bike helps in the rocker arm hypothesis. Keep riding it, but take it easy. Perform a major overhaul when the bike is not needed - like during the winter. If the sound gets louder, or more pronounced - stop riding and fix it before any major damage occurs.<br><b>References : </b><br> My crystal ball isn’t working at the moment.

I dont remember if there is a bolt to loosen the cam chain tensioner adjustment, but if there is, with the bike NOT running, back off on the bolt and lightly tap the tensioner housing with a light mallet as the tensioner may be stuck. If the valve adjustment and this doesn't work, it is possible that you are looking at replacing the cam chain, as it is stretched beyond serviceability.<br><b>References : </b><br> It is possible that the valves need to be adjusted, but it is possible that what you are hearing is cam chain noise, which is common on that make and model of bike.
