rough idling

[Harlequin]

I had the bike out today for a while. It's been a couple of weeks since it got a good run as I'm working away from home these days.
But the bike idles rough. It doesn't quite get to the point where it might cut out but I know it just doesn't sound right. Also, I don't think it's accelerating to well either, it just doesn't feel smooth or even, if that makes sense?
Any clues? something I could try and fix myself?

Have you checked plugs, leads?

Dead badger in the airbox again. Been a spate of them all over the West this winter.

Did it start ok - full choke and then let it warm up and slowly close the choke until it was ok to drive off?

Did you actually ride it somewhere and then notice it not ticking over properly? Does it drive ok otherwise?

It was so cold today that any motor that wasn't up to temp would struggle so I'm not sure what to advise. Uneven tickover might be down to damp on the HT leads/coils or plugs but if the bike was kept dry and warmed fully I don't know.

Is it firing on both cylinders? Lick your finger and tip the headers one at a time. Does your finger sizzle?

Yip, I knew that it hadn't been started in a while, so full choke, it started first time, eased off the choke and let it tick over for a good 10 mins.

It idled perfect before I took it out for the spin. Accelerating on the road felt a bit uneven, like I was driving over speed bumps but far less obvious than that. It was when I got it home that the idling was rough.

Probably better off letting Steve Mac take a look!

I reckon it is, wouldn't it be very severe if only one cylinder was firing? The rough idle is not very obvious, I just know it's not right!

my guess would be youll get a whole lot better resuilts letting someone who knows have a listen , , could be gone onto 1 cyl if it a bros your talkin about , but youll get a lot of advise that might not be very useful , as anyone giving a diagnosis might be just guessing , (as theres not a lot to go on info wise )


id say the first step would be start it for a mo , and turn it off , touch exausts (THEY WILL BE very hot !!!!!!!!!! even after a few secs !!!!!!!!! ) be careful , if one is cold , one cylinder is not running ,
