When I spoke with him, he said it was a 350. The guy was 72 years old. He was traveling through, and heading to barber next. I don't recall what he was driving, but he had a very nice black enclosed trailer. We chatted for 1/2 hour or so between sessions.He tried to tech both bikes, but the one in the back of the picture, did not pass tech due to a leaky fork seal. He was having some ignition issues with front bike. He pulled off in the second session with a fouled plug. He was back the third session, and rode the rest of the day problem free. Cool old guy. P.s I made my above posts from my phone, and realized I didn't type worth a shit!
