2-4-2022: Defective front tire. Noticed a bit of vibration on the front end. Front tire had a high and low side with 3 mm or 1/8th inch up and down . Picture shows max gap with other side touching at 180 deg rotation. Only 600 miles on bike. Was told, today, there was an early batch of Michelin front tires made in Thailand that had similar problems. Replaced it with a 110 90 19 Avon. Problem solved and 2 of 4 weights removed to balance, to boot.
