I just finished machining the 2 piece adapter, and used a 3/4 flange bearing to support the end. Looks like it will work fine.
Pilots are very rare here in Canada, because for some reason Honda decided not to sell them here.
I wish one of the big manufacturers would build a single seat buggy like the Pilot, but with todays technology. I would buy one, because it's a whole lot easier than to design and build them myself.
