Would the machining be too expensive to have longer fork caps built?  Using the same amount of threaded portion and then a longer (lets say 1") portion the same diameter as the fork tube and then the nut portion above it, would this be feasible?

That would work, though you'd need more machining to add the threads etc. Used to be popular in the 70's to extend forks for chops.. we called them slugs, and were generally frowned upon, as they make the fork weaker.

But those guys were adding a lot more length to the forks, I'm not sure that 1" would weaken them much.

There are some people that build them.

There will never be a set come out of my machines.

That added length is what the triple is going to be bolted to. To much risk there, imo.

1" isn't going to weaken the forks, really, you'll just be clamped to the weak point.

There are Pluses and minuses of each approach, I'd favour a stepped top yoke, but that's a lot of machining and cost. We'll see how this option pans out.

In the meantime, here's a pic of the rear shock mount almost finished..

Made the stainless exhaust stubs and alloy collars (which still needed a bit more work in this pic) which is the start of the exhaust system..

Oooh, that is nice.
