1980 Yamaha XS1100SG - Carburetors
Photos and specs of working on the carbs for the first time since I got the bike. It’s very un-blog like, but I’m going to update this page as I go.
Air pilot screw, # of turns out:
- 3-1/4
- 2-1/8
- 3-1/2
- 2-1/4
Intake Ports
Not sure if this matters at this point, but #2 seems to be running leaner than the others.
Carb #4
I took carb #4 off first so I wouldn’t have to mess with the choke lever.
