BMW R80 RT Motorcycle - poor cold starting

[Andy - G8MNM]

Thanks Jamie. The choke is currently redundant, it is looking for a new job!

Col,

Thanks for the very extensive reply to my post.
The bike has only done 20K miles from new and has had only one owner from new.
It is a 1986 model.
I haven't checked much apart from the plugs which are as new.
I must admit that I am much more familiar with my 1975 850 Norton Commando!
I have just ordered a workshop manual off Amazon today.
I plan to check carbs, ignition system etc.
I think it has electronic ignition?
I changed the ignition system on my Norton to electronic which got rid of the points and automatic advance/retard unit which made a big difference.

Regards

Andy
