I have yet to try this. (Waiting for my batteries to return from loan-out)
My ER8 had the habit of steering "buckling" at extreme and then tires would "plow". I thought if I limited the steering it might not do that.
I realize steering will not be as sharp as before.
So, starting with a piece of card stock. I came up with a shape to cut from 1/'8" thick stock.
It will block off the last three teeth in the sector gear.
Drilled and tapped the sector gear and bolted it on.
Now to see if I can load photos.
Apparently not.
I can email pix if someone really is interested.
