What a bunch of geezers! I like going out at 6am with temps in 30s and pushing start-button on my bike and have it Vrrrooom to life in less than 1 crank. Then being able to hop on and ride off without single hiccup in less than 15-seconds after that (how long it takes to put helmet & gloves on). I'm converting my 250 to EFI this winter so it will be civilised!

Carefully check rubber boots between engine & carb. They can have small cracks (or loose clamps) that will suck in extra air and cause temperamental idle.

Also do compression-test, you may have worn-out rings and/or valves that can cause difference between cylinders; resulting in lumpy idle.

Run a bottle of PEA-based cleaner through 2-tanks of gas (1/2 each). Such as Techron Concentrate or Red Line SI-1. Then repeat compression-test and see if there's improvement.
