Language barrier I guess, Edski! Our nations' being separated by a common language, and all that.
Or perhaps I'm just being a bit dumb and mis-reading. To me, a backfire occurs when there's an unburnt fuel build-up in the exhaust system and it gets suddenly ignited; I was referring the the back-popping (spitting) from the carbs.
Sorry for any confusion, me ol' Hondamate!
Need Help! Fuel coming out exhaust on right side?

Listen to Ed, Jason. His method works first time, every time. But, it could all be in vain if your motor's valve train isn't correct:
- 1. adjust the camchain tensioner, as per the handbook/manual
2. adjust the valve clearances, as per the handbook/manual
3. check that there's no valve train backlash as described in the attached pic
4. http://www.honda305.com/forum/index.htm and click on FAQ in the left pane; follow Ed's recipe

I knew I'd read this somewhere and wasn't going prematurely senile:Back-popping from the carbs is normal on twin carb models. There is a logical reason for this on our motors, which I've read but escapes me just now. I also seem to remember reading that it's only one side that back-pops(?).
EDIT: not once the motor is fully warmed.
