I have a 2002 GL1800 that has a tapping sound that is the loudest at around 2000 rpm's with no load. My guess is that I need to adjust the valves. I recently purchased the bike and it has 47000 miles. I'm not sure if the valve lash has ever been checked. Can anybody tell me if I'm on the right track?
Thanks,
Dave

Re: tapping sound
I would agree if the noise is come from there, then check the valve lash.

Re: tapping sound
Your bike has hydraulic lifters
No adjustment
Maybe sticky lifter!

Re: tapping sound
I think they all make a small amount of noise that could sound like muted ticking. I do not know what causes it, but I hear it on almost all GL1800s louder or quieter. I do not think it is valve lash, although they do propose that the valves should be checked and shimmed if necessary. The sound I hear has been their since new, and still sounds the same after 60K.

Not if he has the 1800...the 1500 is hydraulic ...

Re: tapping sound
Most likely the fuel injectors, especially if from the left side. A non issue. But yes, check the if there is no record. Likely they haven't moved if you stay off the limiter and do regular fluid and filter changes.

That's it, thank you. Injectors. Makes a lot of sense.Dark Angel wrote:Most likely the fuel injectors, especially if from the left side. A non issue. But yes, check the if there is no record. Likely they haven't moved if you stay off the limiter and do regular fluid and filter changes.

Re: tapping sound
Spend a couple dollars and get yourself a Mechanic's Stethoscope. You put it in in your ears, and use the rod on the other end to push against things. It's perfect for locating the source of tapping noises like this. You can put it right on the injector and hear if one sounds louder than another - or if one isn't clicking at all!

Re: tapping sound
Ya know, I got a couple of those around, and I always seem to grab the big screwdriver and put it between my ear and the spot I want to listen to. I tend to use the stethescopes when the spot is too far away for the screwdriver and my ear,
