How to balance throttle bodies?
 

I'm familiar with how to balance carbs and the process of using vacuum gauges, but never balanced throttle bodies.

Does anyone have a picture or guide of how to balance the pointy sv (2003 if the year matters)? I did search but couldn't find one.

exactly the same as carbs.

pull off spigot caps, put hoses/gauge on, warm bike up, adjust screw till they balance.

Fair enough, I over-egged it in my head then thinking the electronics would make it harder.

I know where the vacuum take offs are, Is the screw accessed from above or below?

Also is it at all likely that the balance would be different between a standard exhaust and a viper can? Due to the noise of the viper it'd be good to balance them with the standard exhaust on then switch it to the viper once done.

balance is not dependant on exhaust as all you are doing is equalising the butterflies to suck air at same rate.

the balance screw is the lower of the two connecting rods. do not under any circumstances touch the upper screw as you will then have to set the STV which is a PITA.
