I'll try that Clem. I'll probably spray the cogs over the road at that speed. This was the 2nd near miss of the day, first one was caused by the wibbling backside of a lycra clad jogging lovley and a stationary car. I was concentrating, but on the wrong thing as it turns out.
You are right Piet, I think I may well have pussied that change. Realised early on not to tickle it, but to boss it. When I got the bike I would get falsies all the time. Habit. Riding the SF is a real blast from the past IMHO. Everything (apart from the general sweet handling) is a world away, even from my Jota, which admittedly has many many years of care and cash aimed at precise setup.
First SF mod is to isolate the seat somehow from the vibes. It's setting off a ringing in my ears. I'll blame that for my incompetent riding.
