Set off early and soon noticed it was quite difficult to change gear. It took a little while to notice that the engine revs weren't dropping off as fast as they used to when off the throttle.
Stopped in an M&S car park to diagnose the fault; easy! a broken throttle return spring. I carried a spare, and I was back on the road in 5mins.
About 10mins later, the offside front wingstay snapped :(
Yup, again.
Despite the new over-engineered wingstays, it had snapped at the rear support, exactly where the flat piece is welded into the tube. Guessing this must a weak point as we have been here before. Luckily, the CF wings have a little flex in them, so this time it didn't fly off up into the air.
Temporary fix was to wrap it up in masking tape and limp home with a slightly flappy front wing.
