Thanks to all for the info. Put in new CCT and all noise went away. Hub

Ken, Who makes the X-11? thanks Hub

I assume that CCT is cam chain tensioner. Thanks Hub

I just bought a 97 bird and sometimes when it is idleing it makes a growling noise from the engine. It seems to do it only when engine is cold and it does it very sporaticly. It comes and goes. it seems to come from theright side of the lower engine. Pulling in the clutch does not affect the noise. Bike has 29k and the previous owner run Golden Spectro synthetic. Noise quits after engine warms up and sometimes doesn`t do it at all. Anyone have any ideas?
