Throttle Valve Sync. with balls.

Bike Factor @ Ubi Industrial ($30)
Mileage approx 96,000 km

Throttle Valve synchronization also known as throttle body balancing is to be sync every 12,000 km according to Suzuki's Busa Servicing Manual.

This is a simple process to make sure the valves are in sync among the cylinders.
The steps are:
to make sure the engine is warm up first,
life up the tank,
remove the IAT sensors from the air filter box,
remove IAP sensor mounting screw,
remove the air filter box,
disconnect some of the vacuum hose and connect them to the Vacuum balancer gauge,
Sync the gauge's balls with 1 vacuum hose to a mark,
then start the process of synchronizing the valve with the gauge by adjusting the air screw and throttling the valve, most of the time looking at the balls.

Thats more or less the entire procedure, another process to take note, request the mechanic to wash the throttle body, but will have to throw in another $80-90 and its a 2-4 hrs process.

While watching the entire process, the funny thing is, I've saw and extra vacuum nipple with a rubber stopper sticking out of the throttle body, its not in use right now and just wondering if i could use it for a Scottoiler kit ;)


EDITED: Throttle Body Sync should include the Fuel injector adjustment.
