Current status.
Bike fires up every time, still on 1 cylinder.
Last start was with a new plug, didn't help, but it looks like it stopped smoking

Got some ideas what to do next (thanks Chris!), will try that in a day or two.
Have to give my ribs their well deserved rest.


hmm...
how crazy/stupid would it be to put a wee bit of petrol into the cylinder?

Find out whether the cylinder is getting it's own fuel first.

Fuel on spark plug, or is there some other way?

Just sniffing the plug really. you could try add a small amount directly into the front carb throat.

I've tried canking it, then refit plug, start it and over and over again.
Every time the same story.
What I started thinking about... The oil got to the airbox through the carbs, right? They haven't been cleaned, so can they be responsible for the cylinder not working?

Perhaps plugged air jets. Try put a little fuel straight into the carb mouth ... if this lets it fire then you know it's a fuelling problem.

That can be done "through" the airbox?

Yes straight down the carb throat. Just a couple of drops will do, or do it with the airbox entirely removed

:/ Tried that, resulted in a bang from the exhaust, and that back to normal.

When you say back to normal do you mean back to running on 1 cylinder only?

I'd say that means the front pot is getting no fuel. Have you got compressed air available?

Try a burst of carb cleaner down into the air jets with it running, might clear a drop of oil that's blocking them.
