Valve Guide Seals

Postby sw3dl1 » Thu Feb 13, 2014 2:12 pm



I'm in the process of putting together a 1982 GL1100 Standard. The project involves two bikes, the one I am buiding and an 82 donor. The donor bike sat for several years but runs well. Compression readings are #1-172, #2-175, #3-178 and #4-177. The speedo shows 9835 miles, and from associated paper work recieved with the bike at time of purchase, I believe it to be correct.
The bike runs excellently, but smokes like a mosquito fogger from the left side after sitting for awhile.
I looking at replacing the valve guide seals without removing the heads.
I've read several articles about changing these seals. Two methods, rope in the cylinder or compressed air to hold valves in place. I understand the premise. What I don't understand, and none of the articles I've read addresses, is how to compress the valve springs to release the collets that hold the spring in place.
Is there a special valve spring compressor for this job or am I over looking something.
Thanks in advance.

Here's a simple method I saw someone else mention using - a steel plate and a wrench, the longer the wrench the better the leverage and easier it is. Just make sure the wrench doesn't slip, sending collets/parts flying.

Thought I sent this to you in PM, must have not.

Yes, you'll need a spring compressor, that grabs just the coils, NOT an around-the-head type.

Steve, where do think I might find a spring compressor as described?

And just so you know. Even after you replace the seals, your bike will still smoke from the left side after sitting on the side stand for a while. They all do. Just the way it is with the wing engine.

Thanks, I'm aware, but this one seems to smoke more then the other three I have.

The seal procedure externally is simple and there is a thread on this website on how to do it and I have done it myself. However I can never understand why its thought that with the bike on the side stand oil leaks through the valve seals into the cylinders as its difficult to flow uphill into the cylinder. I had terrible trouble with my 82 wing smoking from the left hand bank upon start up and even parked the bike on the centre stand and also leaned it on an axel stand under the crash bars on the right and it still smoked on the left. I had the engine overhauled twice , with virtually all moving parts changed to OEM ones including a careful rebore which I measured as per the book with excellent compression ratio figures. If the oil control rings are not up to scratch it will still smoke irrespective of the compression ratio high figures.After the first overhaul and covering only 850 miles it started to smoke from the left again and after striping down AGAIN I found the wear in the oil control ring on one of the cylinders at 0.9 mm whilst the other one was 0.6 MM. I carefully put new OEM rings in again and after 500 miles the smoke returned. I decided not to pull it apart aging and lived with it in spite of the irritation of the smoke . The two other Goldwings I have had never gave me this trouble even though the lubrication system is the same with the two left hand bank cylinders receiving extra lubrication via the holes in the connecting rods and the left hand big end shells, I have tried to find out why this is case to no avail and assume the bright hand bank are splash lubricated from the gear box. I experimented using different types of oil to no avail and connected a pressure gauge to the oil galley to make sure the oil pressure was not too high as well as overhauling the oil pump and fitting a new oil pressure relief valve ( water pump done at the same time ) The machine has now gone as of all the motor cycles I have had I have never experience this problem!
