Hi, it seems I've got the same problem on my '99 FZS 600, it even stalls several times. I had some cracks in the carburettor to engine inlet rubbers, but when I replaced them, the cracks did not seem to be all the way through. And indeed this Friday I had the same problem again. I'll increase the idle speed a bit to see if that will help and I will try adding some Redex (see carb freeze item in this forum). It only seems to happen when it's quite cold. On my way back from work the bike always runs smoothly. It might be freezing of the carbs. Will let you know how I'm getting along. Please post the solution when you've found it...
