valve adjustment

Postby countrydude2 » Mon Mar 28, 2016 2:42 pm



I have an 08 Goldwing with 43K miles and have been hearing pro's and con's on valve adjustment. Should I have them checked . I am concerned about this and also can this be done at home.

If you aren't hearing any abnormal noise don't worry about the adjustment. It's a Goldwing. That said the job is probably one of the easiest maintenance procedures on the 1800. Nothing to remove except the valve covers.

Honda recommends that the valve clearance be checked every 32, 000 miles. They used a shim and bucket system for clearnces. Unless your comfortable with this system, I would have a professional do the work. Read the service manual for the procedures used. This bike does not have a simple rocker arm system. FWIW :roll:

Keep in mind that if and when a valve gets out of adjustment, you should not hear any noise. With the 1800 engine, as the valves wear in the adjustment gets tighter, not looser.

You are correct of coarse. I am a numbskull. Ignore the previous. Not only that I was referring to "checking" the valve clearances not actually making any adjustments. I'll shut up now.

When I owned an 1800 and frequented 1800 related forums it was very rare to find a low mileage under 100K wing needing any adjustment.
I only had mine 4 years and 46000 miles but it literally sounded and ran like new the whole time and needed no adjustment. The only common misconception that was noise related was an occasional clicking from the fuel injection system.

Do not believe the information about they never need adjustment.
I had mine checked last fall at 35,000 miles and 2 valves required new shims as they were tight.
The dealer did say it was unusual to find one needing adjustment...but it does happen...
I had the dealer do mine while they did the brake recall, and some other work...
Not cheap - but I KNOW I ready to go another 35,000 miles ... :mrgreen:

I have an 09 and just checked mine with 43K miles on the clock... I have a few intake valves that are beginning to tighten up so doing a check is worth while... I will check them again in another 10-20K miles or so and see how they look and then make a decision as to whether I'll do the adjustment or have the dealer do it...

This is second hand info, but I have read that many believe that the only way they are out of adjustment is if they leave the factory that way. Those who say this indicate that it was the last day of the week and the worker is in a hurry to start the weekend, hangovers, basically human error. Hence the question,has anyone had their valves checked and found them fine only to check them a couple or 3 years or 25 or 30K miles later and find them out of adjustment.
