Installed shifter brace, what a difference!

[JohnUSA]

I read that the "play" in the shifter shaft can cause shift shaft seal leak.

In the service records that came with my bike was an invoice for replacing that seal. Upon inspecting the shaft seal, I could see that it was not leaking, and was well seated in it's recess. So, made the decision to protect it (and avoid a future replacement), and install the shifter brace.

I took it for a road test today. Wow! Rock solid shifts, with no more play in the shifter.

If you're on the fence on this mod, get off the fence and just do it.

As a added bonus, although not confirmed,I believe that the poor shift problem also leads to the shift fork not being aligned properly...Maybe causing the abnormal wear on the fork and the dreaded transmission gear noise.

I've read that as well. I wasn't having any shifting problems, but you can definitely tell the difference after installing the brace.

Money well spent, IMO.

Doing mine tomorrow. Finally did the long ride to trade my 89 for the 93 and it isn't done yet. Did my 89 7 years ago worth the hour and a half out of the day for the result.

Why wouldn't you want the shifter shaft to rotate arount the axis if the shifter shaft, instead of around an axis that is 29mm from the C/L of the shifter shaft?

Is that a rhetorical question? Perhaps I do not understand what you are getting at.
What I do understand is that the Honda design is inherently flawed and the shift shaft brace made by a member of this board corrects that flawed design.

Maybe you could restate your question. It is kind of confusing. In the meantime read this thread.

Because there is a secondary shifter shaft that is ofset from the main shifter shaft by 29mm which causes an offset pressure on the shifter shaft that sticks out through the seal which causes excess up/down force in the seal and eventual seal failure and possible excess wear on the internal shifter forks.

Those who say it cannot be done should try not to interrupt those who are doing it.

Huh?

After following the attached link above, I can now see from the photo that the shifter shaft does not rotate like the shifter shaft on my good old Bultacos of the 70's. It truley is a dumb design. I now understand how this linkage would be of great benefit.

Thanks for the information.
