Olivia's been doing weird stuff recently. I'll be just beginning the commute when her revvs will suddenly increase and get stuck there - scary-high with engine screaming. It doesn't happen often, but...
This morning it couldn't have come at a worse time. My side windows were misted up in icy morning darkness, the windscreen wasn't much better, I was approaching a traffic circle, and had cars front and back hemming me in. Suddenly the revvs were hugely high again - instead of merely idling along I was now speeding. Trying to sort that out, not hit the car in front of me and turn around the circle... I didn't see the motorbike coming around the circle next to me!
A split-second later and we would have collided, but fortunately we didn't.
And the revvs problem?
Well I suspect the choke.
It only happens when driving with the choke out - which is a normal occurrence on an early-morning commute. It feels as if the accelerator is sticking - but I think it may actually be the choke cable.
So here goes with a bit of cable-following/fixing very shortly!
