I took my WRR for a 50km ride just to charge the battery, and for the hell of it, before returning to work in early August. About 2km from home, pulled up at an intersection, and the bike refused to idle. Instead, it just ran at about 4000rpm (dunno really, but that's what it sounded like!).
Rode it home and found the idle adjusting screw (air screw) had fallen out! No way of finding it, as it could've been anywhere on the open road.
What is it with this bike? I seem to keep asking this question. I've never had anything like it happen in my life. Needless to say, there are no new air screw sets in Australia, so it's ex Japan again.
