Yes. I own the greatest fox I've ever seen, thanks to Joe. Don't take that the wrong way. It's a tribute to Joe's work, not arrogance. I've only tuned it, put a twin-disc clutch in it, added Mickey T's, and beat a hellcat, ZL1, a Blown S550 with it ;-)
I've got my eye on a couple of minor adjustments and maintenance, but have been pretty busy trying to get my master's degree to go full time on it.
