1979 GL1000

Postby yetex » Sun Mar 04, 2012 7:37 am

So this is my first post with my first goldwing.

I purchased this as a project bike to have some fun in my free time with.

I have a 1979 GL1000 that I would like to tear down to frame to repaint and rebuild. It has been sitting for three years and has the typical problems, dirty fuel, old oil and coolant and locked brakes. The bike has not ran during this three year period.

The prior owner told me that it also needed valve seals. I would like to check the engine to see if it is any good or if I will need to find another one. To check the engine I will want to do a compression test. Prior to this I was going to add all new fluids and clean the carbs, typical start-up items.

Will I need to mess with the valve seals prior to doing the compression test?

Looking for advice

No! They won't effect the compression test at all. Until I got everything else in order I wouldn't worry about them at all. One thing that needs to be done right away, at least before you run the engine much, is to replace the timing belts. This is an interference engine so if a belt breaks the pistons will hit the valves and bend them. Good luck and keep us informed on your progress.

About the valve seals......It is often a mis-diagnosis.....The 1000,1100,1200,1500 etc have one known uniqueness.
If the bike is set on the side stand for a few days,it may smoke on startup.Now this varies depending on oil level,the bike,angle of the bike,time lapsed,etc.It's nothing to worry about.
Now if you get smoke all the time,you've got a problem
