Hope you're feeling better and your condition improves boss. Yeap I agree. Just run the best fuel you want to spend money on and put some type of fuel conditioner in it to help lubricate things a bit more. Lucas makes a fuel treatment that is a stabilizer as well. I won't run any motorcycle without it. I haven't heard of any engine damage as a result of running a classic engine with the newer fuels (ethanol fuel damage is another thing!). These engines are very strong and can pull much more RPM's than most people can stand to pull the throttle.
