Motorcycle Repair: Shifting Problem with 85 GL 1200, followup questions, electrical problem

Question
I've read several articles on this forum about shifting problems with my Goldwing.  My problem is similar to those detailed in a few articles.  I have a few followup questions that I've not seen addressed here.

I've had my problem since buying my 1985 Goldwing GL 1200 SE about 10 years ago but because of bigger problems (mostly electrical), I chose to live with it.  I've recently cared for the last big electrical problem and am now wanting to tackle my shifting problem.

My problem originally consisted of rough down-shifting (4th to 3rd, 3rd to 2nd, 2nd to 1st) and the inability to get into neutral without rev'ing the engine to 3,000 RPM or more.  Recently, I've observed a difference between the idle RPMs while in neutral as compared to the RPMs when the clutch handle is fully depressed.  This got me to think my problem might be hydraulics rather than mechanical.

Recently, I took the advise about bleeding the system at the banjo fitting by the master cylinder and noticed a good amount of improvement.  There is now only a rough downshift from 2nd to 1st and finding neutral happens with less RPM's...like maybe 2,500 or less.

I'm wondering if old hydralic fluid might be playing a part in my remaining problems.  I've not changed it in the 10 years I've owned it.  If so, what is the routine and can it be done without removing the engine?

Also, I had a retired Honda mechanic do some work on my machine a few years ago and was told that Honda had a factory recall that would have taken care of my problem.  He said the engine would have to be removed to switch out the part so I didn't persue.  He said that another possible improvement could come by switching to synthetic oil which I did but it's not made any difference.  Are you aware of any of this?

You guys provide an valuable service to people like me...it's really appreciated.

Answer
your correct i would try nadjusting the clutch to make sure its slowing the engine down when you are up are down shifting . if its out of adjustment it will be hard to shift into high or low either way if you need more help im here ok.

happy hollidays
