I'm on my second fazer now. The first one (2000) didn't have these symptoms and ran fine, so I know there is somehting not right about this one (2003)
In short, the bike struggles to run on cold startup without choke. It doesn't need full choke, just enough to get it to idle above 900rpm.
Without choke it will start, but idles very low (600rpm and slowly drops) and will stall within a minute unless I intervene with a touch of throttle. This is even now, when the weather is warm and it shouldn't need any choke.
Once the bike has been run a while the idle is normal, approx 8-900rpm, so the idle adjustment is OK.
The bike is garaged, I replaced with new plugs a couple of months ago. It has a K&N filter and a Scorpion exhaust (without baffle).
Any ideas? Is there anything other than the idle speed I can adjust?
