Malcolm and Alexander Smith raced one close to this vintage at the Mexican 1000 rally back in May. It had the plastic tank mentioned.
Seems like they grenaded the bike too, rebuilt it trailside and still pulled off a good run. They scored a 3rd place behind a 950 SE and a Honda Rallye of some type.
