Anyone know of supplier?

I know what you mean, I’ve made quite a few for drag bikes in years gone by.

I don’t think you’ll find an off the shelf sprocket to fit as it is a specialised application. You should be able to find a machine shop that will cut and re-weld your sprocket. With an experienced welder we never had a failure and one bike was running a big block Kawasaki on Nitro.

I can’t remember off hand how thick a TT500 sprocket is but you could almost cut two so they overlap (inner and outer) and weld them back together.

You need to consider having enough room in the centre of the sprocket to not only fit the retaining nut but being able to get a socket on there to tighten it. We often had to run a fairly large sprocket to be able to do this then correct the gearing at the back sprocket.

We used to run an outrigger bracket and bearing for support over about 20mm but this also depends on the amount of power you’re putting through it, how long it’s going to run for and how often.

Great info. Thank you so much. I was under the impression someone offered them. Can I pay you to make me one. Send me private message.
