Question about 1981 Honda GL 1100 Innerstate Gold Wing
I have 1981 Honda Goldwing and the mechanical valve lifters and rocker arms make a ticking noise after the oil warms up.I have set the valves to specs and have set them a couple of thousands tighter and either way they still tick. Any solutionws would be helpful.
The ticking sound is most likely caused by uneven wear on the cam lobes. The next time you've got the valve covers off, take a look at the cams and you will likely see scuff marks on one or more of the high-points of the camshaft lobes. This can cause a ticking sound each time that part of the lobe comes in contact with the rocker arm. The only cure for this would be to replace the cam and rocker arms - which is not worth the many $$ it will cost. The noise may be annoying, but isn't anything to worry about. My Goldwing started making a ticking sound at about 90,000 miles - and continues to this day, now with more than 169,000 miles on the engine.
Uneven cam lobe wear can also cause lateral movement of the rocker arms - and a ticking sound as the rockers move slightly sideways on their shafts (note the springs on the shafts that hold the rockers lightly to one side).
I should also mention that pitted valve stem tips can also cause a ticking noise. In any event, do not run the engine with less than the specified .004" valve tappet clearance as this can cause valve damage and compression loss.
