Anyone using a manometer to set the TB balance?

I have been guessing the idle bypass screw settings for idle by just keeping them turned out the same distance with the target RPM. I finally got my manometer in and checked the balance. Their was quite a bit a difference in between the two cylinders.
Correcting this made the engine idle so much smoother and stable. Worth the $40 for sure.

If you're happy with the way your bike idles and runs with the changes you made, that's great. However, there is a little more involved in properly balancing the throttle bodies.

Ideally, you would use the linkage throttle body linkage adjustment screw and your manometer to balance the throttle bodies at 3500 to 4000 rpm with the air bleed screws fully closed, then use a gas tester to adjust the airbleeds to achieve the same CO level at idle. This should be done at operating temperature.

You might find with the adjustments you've made at idle, that the bike does not run as smoothly as it could at steady part throttle.
