Shift Shaft Mod

[Ben350]

Have my cases split and am doing some work, and want to get the tranny working as good as i can. I have a couple questions about mods i always hear about, but you never see an explanation of them. At the moment i have the RZ shift forks with the roller followers, a new shift shaft, and i ground the shift star.

 

So what exactly, in detail or even a pic, is the shift shaft mod?

 

Also i want to side cut the gears on the dogs where the gears mesh together, anyone have a pic of it done? Is this typically only done for 5th gear?

 

Thanks for any info

There is a different spring put ont he shaft that makes it not-so-stiff. This in combination with the roller bearing that rides on you shift star that you can get through cascade, and the shift star mod it will get it about as good as you can get without splitting with cases and side-cutting the gears or dropping in a duneable. If you take it all apart and look at how the trans really works you can find a few other things you can do to ease things up a little. The addition of springs on certain shafts inside the cases and some cutting done to the shift drum can make things smooth as butter, even under power.
