Congrats on the new bike. As others have pointed out, modern EFI and ECU tuning does not react like the older carb bikes of the 60s and 70s. I highly recommend you not put the AVGAS in your new bike without other tuning modifications done to the ECU first. The current ECU is designed to operate within certain program parameters. It will make slight adjustments to timing and A/F but you throw in something radical like 100+ octane AVGAS with lead which burns slower than 87 or 89 unleaded and you are headed for heartache. Even with low lead levels, any lead present will foul the O2 and likely ruin the cat in short order. I personally run 91 unleaded in my bike and put in a very small amount of Star Tron gas enzyme treatment per instructions at every fill up. This stuff counters the negative effects of ethanol added to modern fuel as well and keeps the gas fresh for longer periods of time. I am also running a Power Commander V with slip on muffler for better performance and fuel mapping. Enjoy the bike and ride safe.
