Carb problems or is it something more?? Fazer 600

If the engine is only pulling 150Hg there's something very wrong with the pilot circuit probably the screw setting.  Unless you can get the intake vacuum between 230 - 250mmHg you're never going to set the carbs up correctly and the bike will run like a dog.


I suggest you recheck each carb and what you've or I think you said mate put in and how.
