Carburetor
Adjustment:
Left/right throttle synchronizing; There is a trick
to synchronizing your carbs. Take 2 spokes and cut them
in half. Keep the threaded half. Then disconnect both
spark plug wires from your spark plugs. Screw the spoke
nipple half way onto the threaded end of your spokes.
Then place that nipple over the sparkplug and the other
end of the spoke into your spark plug cap. Now you can
ground out one cylinder easily by touching a long screw
driver first to the cylinder and then to the spoke.
You want to run the bike on one cylinder.
With just 1 cylinder running, turn the idle speed adjusting
screw until the idle is barely keeping the bike running
on one cylinder. Then screw the mixture screw until
it raises up the RPM of the one cylinder you’re
working on. When that stabilizes, go back to the idle
adjusting screw and turn it out until it lowers the
RPM so the motor just barely keeps running on 1 cylinder.
Now repeat this for the other side.
Remember, only turn the idle and the mixture screw slightly,
about ¼ turn at a time.
For high speed synchronization- This is done via the
cables that run into the top of the carburetors. There
is a stop nut on each throttle cable. Adjust that nut
until both cylinders sound the same at about ¼
throttle opening. |
