rough idle in current freezing weather

[jimv50]

Can't find anything online but do these bikes run rough when idling in the current freezing weather?

[Norniron]

Are you using pods or original filter and airbox?

[jimv50]

All original set up,no 'enhancements', correct good condition plugs etc,runs alright when thoroughly warmed up during a good run.
Just thought the bikes might be  sensitive to the cold.
I've screwed the idle up to 1300 rpm just to stop bogging down at the lights

One possibility is water absorbed by the ethanol in the petrol freezing and partly obstructing a jet due to the inrush of already very cold air.

Petrol all good, all flushed through after recent fuel tap debacle, all carb bowls drained and petrol looked good.
A thorough spray of carb cleaner will have to be done just in case.
New brass and steel feeler gauges ordered just now to give a bit of  tune up which I hope will help.
The more I do to it the less likely I'll trade it in against a Ducati Monster I've got my eye on.

RS tools delivered new brass feeler gauges today and air gap adjusted from previous 0.85mm gap to 0.35mm.
Certainly started up on the choke better and ran a bit smoother, will have to wait for another day to see what it's like on a run.

Why brass feeler gauges? what's wrong with standard steel ones

[jimv50]

Nearly all the guidance on measuring the air gap in electronic ignition systems told me to use the non-magnetic feeler gauges.
I certainly don't know the science behind what may go wrong but for the sake of a few Euro I wasn't taking the risk of either shorting something out or just plain not measuring the gap correctly, and I get another tool in the bike tools box 

PS where in Glos are you, I was born in Thornbury

Apparently some sensors can be knacked by magnetisng them with feeler gauges. I looked it up when I wondered why I had one brass feeler in a set.

[Bryanj]

Didn't know you had electronic ign, Im just south of glos near junct 12

What was I worrying about? Honda manual shows someone stabbing away with a screwdriver at the pulse generator.
And it seems the bike has 'transistorised' ignition rather than electronic, how things move on..
