Adjusting 919 Mirrors

How do you adjust the mirrors at the base? I tried turning the screws away from each other, but the top one just started to strip. I tried using PB Blaster on them too, no luck (that stuff always works).

Is there another trick to it or should i just think about getting other types?

I am having the same problem, I can't adjust my mirrors down there at all, it is like they are fused together. We have tried everything, even heating with a torch...no luck thus far.

hey teksi, you need two wrenches, and you have to work them in opposite directions. The lower nut is standard thread, clockwise to tighten. The upper nut is reverse thread, counterclockwise to tighten. It's a little counterintuitive at first but not bad once you get the hang of it.

If it doesn't make sense, hold the lower bolt with one wrench and loosen the upper bolt (clockwise) with the other wrench. The two parts will seperate.

Worth every penny for the safety factor. The stock mirrors provided a nice view of my elbows but not much else.

That's what i was doing and it just started stripping the upper nut. I just quit before i broke it.

Using this information, I went out and gave the mirrors hell and amazingly they broke loose (I was stepping on the wrenches). Mirrors are now adjustable.

Excellent info when needed. Nice. I've never had to adjust them, but now I know what I need.

stripped bolts suck! May not be worth the effort to fix. Maybe try to pick some stock mirrors up off of somebody here, or pick up some other style stock mirrors from a different bike, like an Suzuki SV or a KTM Duke.

These mirrors are a stock set I bought from a member. The ones from my bike are scratched and the new ones don't line up with the thread on the mounts.

I'll try again. Is it designed so there's a threaded part at the end of the mirror with a nut on it (top nut), and the bottom nut with threaded part screws onto the thread on the mirror?

There might be a diagram at ronayers.com as to how they come apart.

If you're holding the mirror in your hand with the bottom part still attached (the stem part you can't get off, i think) , that assembly screws into the bar backwards which makes you think it won't fit.
I got a set from somebody on here too and you're right, those things are tight! I stuck it in a vise in order to get a good grip.

Fewer things in life can be as frustrating as those dog damn mirrors. These days I'm pretty good at it though.

Good instruction, btzung.

I closed my garage door last night and my mirror was poking into it's path. The garage door adjusted it quite a bit.

I think the design of the mirrors is a good example of how neurotic Honda engineers are. They are designed so that either direction something collides with the mirror the mirror can get knocked loose rather than breaking--or worse--knocking the direction of the steering off and causing an accident. Seems like a good thought but makes it more painful for us backyard mechanics.

Teksi, the bottom bolt is actually an adapter that screws into the handlebar like a normal nut. The mirror then screws into the adapter "backwards", it has a reverse threaded stem that goes into the adapter.

The upper bolt is then used to tighten the mirror onto the adapter. This bolt thread is also reversed, so you have to turn the upper bolt clockwise to loosen it.

All in all three parts, from top to bottom:
1. a mirror with reverse threaded stem
2. a reverse bolt, and a
3. an adapter that switches the reverse thread input into normal thread output.

Glad the last post was helpful for you, motorwerks!

Thanks for the replies/help. I thought that the mirror came apart in 3 parts like that, but didn't realize the thread on the mirror was reverse, that should help alot.

Those things will snap like a twig. That stem is surprisingly soft.
I had to drill it & easy-out it when I got my bike and it took all of 30 seconds.
