Topic: Missing Steering Stop

[timbo750]

I have looked at the steering a couple times and thought something doesn't look quite right, finally worked it out - the steering stop is missing. I am trying to work out the correct size and geometry to make a new one and weld it on.

I have done a drawing but I am pretty sure the contact face does not line up back to centre of the steering stem. I have measured of another fame but it doesn't look like its in quite right either, I think it has been repaired before.

Can someone please give me even an indication of how important the accuracy of the bit is?

If it is not crucial to be 100% correct then it will be a quick job, however if its very crucial to be spot on then I will make sure it is.

It's main role is to stop the bars hitting on the tank in low speed turns.  Take from that what you want

Depends on your handlebars.  If you go with clip ons, I understand the original stop will not be enough.  If you go stock, anything will work. 

You can always mock it up with triple tree in and handlebars on.

start by making it a little bigger than you might guess. You can always grind it down to fine tune it.

If you are going through the trouble of making a new stop, and you aren't worried about a 100 point accurate restoration, I would recommend making the stop adjustable. This way you can accomidate all sorts of bars.

For a long time I rode my 78F with the dunstall tank with a set of drag bars because I couldn't fit anything else that would clear the tank (and even then one of the screw heads would sometimes scratch the paint). My fix was to drill the stops on the trees to accept an allen head screw and 2 nuts (one to lock the stop in place and one to pal nut it) . From there I could adjust the stops for clearance.

If I were you I would get a small piece of bar stock or two, drill it and tap it for a screw and then weld it to the frame. With the screw and nut all the way in should be stock steering lock.

Even from the factory these things weren't that accurate, I've seen bikes that have had more left lock than right and vice versa. As long as it isn't hitting bodywork you are all good.

Geeto, that great. The bike wont be stock original, it had a few parts missing and I will make or buy what I need, and definitely trying to make this one. Do you know what size screw/bolt you used, I would imagine 6mm or 8 mm otherwise there might be too much bulk.

It's funny you should mention the factory ones not being accurate, the other fame I have is exactly that and it looks like someone has put a weld tack on to it to try and fix it. I thought that maybe it had been damaged in a previous life but your explanation fits.

If I recall correctly it was a 6mm stainless allen head bolt out of a generic box of machine screws I bought at a car show. wasn't very big.
