How to TB balance

[rossguzzi]

I am still getting use to navagating around this site. I have not found how to balance the throttle bodies yet. Can someone point me in the right direction please?

I am not sure how it is done with Throttle Bodies... but it should be similar to the links done with Carbs:

Not sure either how it works on the fuel injected bikes but here is a penny tech solution on car syncing on a carbed LC8

Here is a link to the TBS on a 990 SuperDuke:

I use the vaccum hoses that connect to the IAP (intake air pressure) sensors. Theres one on the frame beside the left side of the airbox and one just behind the radiator filler cap on the right. It's just small sensor with one thin hose and elec plug connecting to it, mounted in a rubber holder. Just pull the hose off, stick a joiner in the end of the existing hose and then connect the carbtune hose to that. You must disconnect the Elec plug too, or it will stall when running. You will have an FI light to come on too, due the the disconnected IAP sensors but don't worry about that.

The adjustment/balance screw is inside the airbox, on the left side of the rear throttle body. You need to raise the tank/remove the air filter to get to it. Then just tweak it until she's running sweet and re-assemble.

I do mine every minor service.

So sorry I meant carb balance. I am so use to talking about throttle bodies (FI) !

Thanks for all the links etc.
Cheers.

To sync the throttle bodies on FI 990's is it best to mechanically adjust the TB screw or make the adjustment thru software (TuneECU)?

I use one of these:


Couldn't be easier... stick it in one.. stick it in the other.. make sure the reading is the same.
if it isn't adjust the screw (mentioned above) until they match.

You are basically measuring the actual air consumed.

Hope this helps

In my CBR F3 and F4i, which is Fi, I do it the grandpa way and as never failed me.

A piece of wood with 1m x 15 cm with 4 fishtank silicone hoses plugged together on the bottom with some small T´s and filled with regular car/bike oil.

Just plug the other end of the hoses to the TBs and adjust. Just like with a Carbtune only waaaaaaaaaaaaaay cheaper
