Starting problem..???

Well !!!!!!!!!!!
I'd recommend that you flush out the tank, float bowls, and possibly replace in line fuel filters to ensure that lingering pockets of diesel don't remain to cause future 'mystery' issues.

I make sure that all my diesel/kerosene containers are marked with a big "D" or "K" on them too!

That was a learning experience !!!!!

Don't know if they are available in your part of the world, but I have seen yellow fuel containers for diesel fuel locally .

Much worse to run a diesel on gas than a gasser on diesel    Glad the bike runs well now.  Sounds like it did run for a few seconds on the diesel with clean carbs, so your plugs are probably fouled.

Gonna have to add that to my poor starting checklist!  I'm surprised you didn't notice the fumes when you took the carbs apart.

As long as most of the diesel is out it should be fine... after all, the R65 manual calls for draining the gas tank and coating the inside with motor oil for winter storage!  Anything left will dissolve in the gasoline.  Might even give you a little extra lubricity

They're mandatory here.  Stations won't sell you diesel to put in red gas cans.
