Pictures of how I cleaned and adjusted the carburetors on my 1985 1986 1987 Suzuki GSX-R750 motorcycle.
These carbs are ganged. Bolted together and their function syncronized. How that works is something like this.
But first, lets pay some bills:
Here is the choke rod. Choke rod? That can't be right.
Anyway, the choke rod controls all 4 starter plungers on all 4 carbs.
This ensures that all carbs get the same amount of "choke".
The choke rod passes through this hole,
where this ball bearing presses on it to keep it where you set it.
When I try to install the rod, it pushes the ball bearing out of its seat.
So I used that handy ice pick again to press the ball bearing
down into the spring while I installed the choke rod.
Similarly, all 4 butterfly valves are operated sycnhronously.
The linkage between butterfly valves can be adjusted.
To do this, I loosened the likeage between carbs 2 & 3.
I adjusted the synch between carbs 2 & 3 by turning the balance screw
until both butterfly valves exerted the same pressure
on the little wires. I was careful not to let the wires scratch
the butterflies or the throat of the carbs.
This balance screw spring was out of place and not putting the proper pressure on the next carburetor.
I straightened out the spring and reinstalled it correctly. Then I balanced those carbs.
This is a bench balance.
Balancing them with the engine running using a vacuum gauge will generally yield better results.
- Next I sold out to make 02¢
so I can fulfill my lifelong dream of owning a 1986 944 with blown head gaskets.
But no minivans!
- Then I finished my beer.
