Small question

[MikeD]

I built three warriors I have been riding one while the other two are being powder coated. The one I’ve been riding has the chain come off the pulleys periodically is this common or is there a cure for the problem.

All the diverter pulley'sused really need a simple "chain-keeper" to prevent this. It is fairly common to use one.

You want something like this on the top and / or bottom of the pulley.

In theory, a chain will only come off due to chain bounce, a too shallow groove, or misalignment that can occur with different gear selection. Fitting the pulleys so that they can slide sideways will provide automatic alignment adjustment, a deeper groove is obvious, and the keeper in the image should do the rest. Just make sure that there is no room for the chain to fit between the keeper and the pulley.
