The profile photo is a road in Big Basin National park, south of San Francisco. I rode that bike ('70/'71 Commando) for a few days in the region before riding it from San Jose CA, through OR to the INOA 2018 rally at Elma WAstate. All up 4,000 km (2,500 miles) in just over 2 weeks.
The temperatures in CA & OR during the trip were 40°+C and fires destroyed some towns along Interstate 5 (Redding CA burned up a few days after I arrive back in Adelaide).
The rally was great: my tech. talk session was well received and more orders generated through INOA member word-of-mouth since then.
I use Trispark units on my Commandos. Riding the 850 home from 2018 Phillip Island Classic racing was in 40°+C temperature (the sportsground's outside thermometer at Horsham showed 46°C).
The bike cruised at 100 --> 110 kph all day, once we got off the Queenscliff ferry except for the road blockages in Geelong due to a pushbike race... keeping airflow to the engine was a real challenge (hadn't yet fitted the oil cooler to that bike).
good posts Owen, I enjoy, back in '91 I spent 3 1/2 months in the states, saw about 30 states, many I would love to go back, some not so. was disappointed then of hardly seeing any bikes on the roads but think different now. Think you know your way around Commandos see your comments other sites, keep it up
