Jay, thanks for the compliments. I have 4 more being made and I'm done when they are gone. These 15 I've made/sold have served their purpose - helped out my machinist friend and helped the community here. I've lost about $100 total in development, free ones, discounts, and 3 day priority shipping - but I enjoyed the journey getting they designed and installed. There may still be a demand out there if people knew how easy it was to service their top-ends with them. You or someone else should make and offer these.
Sam, I've seen my bike without the lower tubes and it's scary that anyone would put a bunch of horsepower in a frame with the thin backbone tubing alone. I had to come up with some way to service the engine and not remove the frame, but couldn't stand the thought of the one tube holding my life in balance.
Regards,
Gordon
