Pilot screw
Garfeild:
I’ve got a 2003 fazer600 tickover is a bit lumpy, it seems that it’s running on 3 with no 3 exhaust pipe not getting hot as quickly as the others, ignition wise all is ok, new plugs fitted all sparking
So got my carbtune all set up, and what I found is that no 3 didn’t move off minimum setting with the other 3 at various settings.
I managed to balance 1&2, then went to do 3&4 but again I couldn’t get no 3 to alter, I then set the other 3 to no 3 to try and get it to run smoothly
I’m wondering if the pilot screw is not set properly, but where are they? The manual shows a view, but it’s a joint manual with the thundercat, and it of course shows the cat carb not the fzs one
Anyone got a pic of where the pilot screws are?
TIA

Use the download section,click on Downloads top left, download FZS600 workshop manual. It's in the carburetor section, they are under each carb facing up outside the float bowls.

Found this posted shows what to clean but one of the pics shows the fuel screw (pilot).

Thanks, now I know what I’m looking for il try and check the setting on those in the next couple of days, no3 looks like it’s a pain to get to, possibly remove starter motor?
bandit:
When you adjusted the screw for 3 & 4 could you get 4 to match 3, if so then turn the middle screw to try & match 1 & 2 & 3 & 4.
Here is a write up on balancing & throttle position sensor settings. Also recheck the throttle position sensor settings after balancing also.
