I found brass #4 washers. If this is the correct #4, mm measurements are below. Note that the measurements are exact, I just had to lay it down in the first image and it just looks like an inaccurate position.

Yes I do sell washers like these and the jets you need.
If you have not already found them and want a set just PM me.

Customs example:
Assuming a combined price of repaired cam and, jets, washers etc at around 2500 DKK... and 200 DKK for freight.



Customs calculator with setting for motorcycle parts:


Resulting price (Given that it's caught in customs):

Regardless of condition, it Is a refurbished, Used part.
Lumpier and shinier than the old one.

Are we still talking main jets here????  

Can this bike be rejet without taking the carb out?

I'm gonna add a little tip here for removing the jets with the carb in place:

The jets are soft brass, and the slot for the screwdriver runs across the hole in the jet, and they can stick, and you need to get the screwdriver into a narrow channel. I'd suggest making sure you have a small screwdriver that is in good condition (a clean edge). I bought one that is also narrow (it doesn't have the flare on the end that most do). I only use it for replacing jets. My girlfriend picked it up one day to undo a screw on a door or something - that was the day she learned the rules about my tools  

It might seem like a small thing, but if you're going top poke around in the carb in situ, you don't want to bodgy anything up, otherwise you'll be removing it anyway to repair the stuff you mashed outta shape.

Aaaand ... as others have said before, swap the carb-bowl screws with some SS allen key screws (and put some anti-seize on them) while you're there. It makes life easier later.
