Hi, Jimbo, I stripped the carbs on my K3 and ultrasonic cleaned them. A friend who`s a retired Honda mechanic set them up for me and the bike ran lovely. It then stood for over 12 months (house move etc), I tried starting it but it wasn`t having any. A squirt with carb cleaner and fresh petrol and she`s running as good as ever!!!!
My mate, the ex Honda mechanic says that he wouldn`t have stripped them, just used carb cleaner and emptied the can while it was running just to make sure!!
Just my twopenny worth.
Cheers, Nigel.
