Valve Seals

Post by billball »



Hi everyone,
I have a beautiful 1983 GL1100 with the full Hondaline package and I love this bike.
My question is, After sitting overnight it smokes for about 2 minutes, I am an Automotive tech for 40 years
and not knowing bikes a hole lot I'm thinking valve seals. I'm going to do the Timing belts soon and I purchased the valve
seals. Can the valve seals be replaced without removing the heads. On an automotive engine you fill the cylinder with shop air,
Tap the valve to make sure it's seated and with a valve spring tool, remove the spring and change the seal and reassemble. I have never even had the valve covers off
yet but would like some advice before I do.

Thanks
Bill Ball

You can do it exactly the way you describe. Others have taken thick cotton rope, push it into the cylinder through the plug hole, then rotate the engine to push the piston up, which pushes the rope up against the bottom of the valve, so that the spring and seal can be removed/replaced.

Goldwings (boxer engines) will smoke on the left side if parked on the side stand. Put it on the centerstand and see if it still smokes after sitting over night.

This is probably it. My 1500 pushes a bit of oil smoke in the morning if I leave it on the side stand overnight. I have taken to leaving it on the center stand if possible. Not to say the seals won't be a little worn after all this time.

The difference between automotive and bike mechanical is all in your head. Nuts and bolts is nuts and bolts. The appropriate JIS bits are a big help on most of the eastern bikes, even if they are built locally.
It doesn't matter what you ride, as long as you have your knees to the breeze.

Thanks everyone for the great reply's.
I have purchased the valve seals and will tackle it next weekend now that I know I don't have to remove the heads.
Thanks again

I've been wrenching my own bikes since the 70's and never knew this until about five years ago. Have never stripped out a screw head since I got the right screwdrivers and driver tips!
