You didn't say, is the engine is at operating temperature when you notice this shudder or is it there all the time?

My GL1500 had the shudder when it was at operating temperature and with a passenger on board. I switched to Synthetic oil and I have not had a shudder since. That was with my 1999 GL1500. I started using Synthetic in it at about the 10,000 mile mark. I put 160,000 miles on the motorcycle and it always operated flawlessly. I have a 1998 GL1500 now that I bought with about 2000 miles on it. I started with Synthetic oil in it at about the 8000 mile mark. I have 99,000 miles on it now and it too operates flawlessly as well.

I used Mobil 1 oil initially. Then used some Amsoil. And now I use Shell Rotella T 100% Synthetic exclusively. No issues at all.

How many miles are on your motorcycle? If the shudder is there all the time, it may be due to a build up of oil and combustion by-products on the clutch plates. I have heard of people that put a quart of Marvel Mystery Oil in with an oil change and run the bike for a few hundred miles to clean things out inside the engine and transmission and they had good results. I have never tried it myself so I can not say if it works or not. You might check with one of your local and well respected motorcycle mechanics and see what they have to say.

Is the shudder in the driveline (i.e. the clutch shuddering) or does it feel more like it's coming from the engine?

Good day, thank you for the replies.
"WingAdmin" >>>> It feels like it's coming from the motor, cos the whole bike shudders. At both cold or operating temps.
"Mike B" >>>> I hail from South Africa. 97000 km's (about 60000 miles). I noticed that while driving in top gear at a lower speed (60km/h or ± 38 m/h) and opening the throttle, it also has the same shudder only for a few seconds, until speed increases. Also when gearing down for cornering.

Could be just the primary chain, which will shudder and make a lot of noise if the carbs are out of sync. Syncing the carbs might fix your problem.

Hi there, i also think that it could be the carbs cos she is idlling above 1250 rpm and when she is cold she idles
just under 1000 rpm and you can hear i sappose wat sounds like the primary chain, but unfortunetly i
wont be able to work on her for at least the next four to five weeks i had an operation on my right hand
to release the presure on the nerve witch they call tunnel syndrome this makes your fingers go completly numb, o yes you have a very good looking wing and all my regards to your wife and daughter god bless and keep well until our next chat ,punkies.

You might try adding some Seafoam to the eng oil, riding GENTLY to bring eng up to normal temps- then dump the oil & filter, and replacing with fresh oil/filter(Shell Rottella oil is good) The Seafoam should disolve and clean all the sludge and gunk off the clutch and inside the eng- oil will be dirty when you drain- and, yes!! if the carbs aren't synched well, the engine will be out of balance at low speeds, will cause the primary chains to slap, make lots a noise ect- The carbs must be right in all respects- they have an effect on everything else. Let us all know what you find- Dennis in Anchorage
