Hi , new to the group but been building bikes for many year and just stuck on a 1994 K1100LT 16v.

need some help from the brains trust if possible, Cheers

the bike is Aussie delivered, 170000km on the engine but mechanically A1.

running new bosch fuel pump and filter, pressure reg working and have 36psi fuel pressure.
new EV16 4 nozzle injectors that flow 120cc as per the OEM injectors.
new engine coolant dual sensor, TPS set, ECM checked for faults history (engine temp sensor), TPS set via test box.

bike is running very rich at idle on our dyno using 4.9v wide band o2 sensor probes, blk plugs and exhaust.
I have balanced throttle bodies via air bleed screws and the O2 trim pot has no effect to mixture.

bike is a custom build running pod filters and the air temp sensor is located against a pod filter.
electrics still run the temp and charge globes, temp light comes on with key on and goes out when engine starts.
bike temp is good running a bsk alloy radiator.

I am totally stumped as to why this engine runs very rich at idle?

Because these crap air filters do not allow enough air at idle.
There's no difference with the OEM air filter and no filter on a power bench.
So the OEM filter provides a free air flow. 
How could any filter do better?

yeah ive come to the conclusion that these K&N pod filters were the cause so will fit the oem airbox back on, then its all stock fuel management wise.

That will also put the air temperature meter probe into the intake air flow where it belongs.

Pods will work but as jbt indicated, more volume is needed like was done here.
