Can someone help me with information on the head steady on my '61 ES2.
When I bought the rebuild project it had no valve lifter spindle, and did have a head steady bolted to the two lugs on the frame. It's a Y shaped piece and is fitted to the pair of front studs holding the rocker box down. See photo.
However, now that I have fitted a new valve lifter spindle, the lifter arm fouls the outer edge of the head steady such that it won't fit.
What's going on?
I have attached a very enlarged and cropped photo of my ex-bike if that helps. Seems to me that the left horizontal edge of the steady was concave, allowing room for the lifter lever.
Thank you for this Michael.
Maybe the head steady bracket comes from a twin.
I wonder if the previous owner took out the spindle so he could fit the bracket.
If so he must be a fair size, to start it without a valve lifter.
I'll modify the bracket
As Michael suggests, I don't think that's an original head steady fitted to your ES2 Richard, nor is it off a twin, which is a different style. The horizontal plates were concave on both sides but I'm sure you can modify the left side accordingly. Below is a cracked original shaped one showing the profile as well as a couple of other shots showing dry fit prior to brazing of a more substantial home made replacement. A bit non standard as it's a 19S engine in a wideline frame, but you can see the arrangement with regards the valve lifter.
Thank you for the photos Peter, I'll certainly go the route of modifying the bracket.
Pity, it's just been nicely painted.
