Stuttering engine below 4k (FZS600)

[darrsi]

I finally go the Fazer back from the workshop. The problem was with the carboratour and valves. There was too much fuel getting into it and that was a reason why it was losing power. Proper cleaning, including some liquid added to the fuel, solved the problem. Now it runs like brand like Thanks again for all advices.

Hold on a minute, you need to explain this one a bit more?
Too much petrol can also mean not enough air, so could simply be a stuffed up air filter, or badly adjusted carb screws, or something sticking in the carbs.
And what liquid exactly was added to the petrol?
I've never ever known a mechanic to do this, they would much rather clean carbs manually for proper results and earn a few quid out of it in the process?
"Proper cleaning" would never involve additives, it would involve a 3-4hr labour charge.


Bit more info please?
