Default Cbrf1- pc23 1989 mirror adjusting - how??

Hi Guys,
I'm new to the forum and just bought a 1989 CBF600F1 - PC23 93 BHP spec. with low mileage. Red, White,Blue fairings.

HOW DO I ADJUST THE MIRRORS PLEASE ?
The mirror glasses are not a the correct angle for my height and I am looking for the means to adjust their position.
1. I have pressed gently against the glass and tried to swivel it, but can't get it to move.
2. I have peeled back the plastic boot on the support arm to see if their is anything locking movement. All I can see there is a few threads from the stem of the bolt which is secured from inside the mirror shell.

Appreciate you help.

Thanks Dennis

The glass does not swivel within the shell, the shell swivels on the end of the arm and the arm swivels in the mounting bracket.

If the arm is too stiff to move then you can loosen the mounting bolts but both ends should move reasonably easily.

Thanks for your reply Ed much appreciated

The mirror shell is rigidly bolted to the alloy arm, the alloy arm is rigidly bolted with 2 bolts to the fairing, so no adjustment there.
Some pictures i have found pasted below.

This seems to be the setup that is on my pc23. The mirror glass is held in a plastic surround which clips around the glass. These are not secured to the outer shell of the mirror housing. It looks as though the glass should swivel around, but mine doesn't.
Has anyone dismantled one or freed off the adjustment system or replaced a mirror glass ?

Thanks
Dennis

It looks to me as though the pictures of the shell with the mirror removed show a cup in the shell with a part spherical metal fitting held down by a screw. Assuming that this is correct then loosening the screw will allow you to swivel the plastic with respect to the metal and thus change the relative angle.

I see no photos of the other end of the arm where it mounts to the fairing.

Inner mount at fairing. 2 bolt fastening with a riveted alloy arm to mirror head.

The rivet in the arm is solid and rigid to assemble the flange to the arm as part of a "one piece" assembly.

I have looked to see if replacement mirror glasses are available, but not yet found any. If I had I might risk applying greater pressure to try and free of the swivel shell that we can both see. It is risky trying to peel off the plastic rim around the mirror glass to get it out, for the same reason.

Sorry about the picture sizing Ed, I haven't got used to the method of moving pictures in and out of the gallery.

I think you can see the problem I've got, and it's tricky to find a solution unless someone has already tried it.

I will live in hope at the moment

Sorry, I have seen mirrors with the split shroud like that but my F1 was not fitted with them. The inside is certainly not familiar, mine was like the F2 where you could loosen a bolt to allow the arm to move.

Many thanks for trying Ed.

Much appreciated

The glass inside the mirror on my 1990 bike moves although when I bought the bike,it was totally frozen with no movement.
I took them off,squirted wd40 inside the mirror housing,left it for a day and now the glass moves inside the housing
Hope this helps

Hi Flyin2wheeler,

Thanks very much for your reply which is most helpful.
Did you do this some time ago please ?.
I have been rather reluctant to squirt anything in there. The reason I asked is that I wondered if the WD40 has affected the silvering reflective layer on the back of the glass.?

Has it affected the mirror reflecting in anyway ?

Thanks Dennis
