Anybody know where you can a good aftermarket needle for the Mikuni BSR42 carb, without buying an entire Dynojet kit?

 

I would like to find one also. It would be nice to have a needle that could be run in the mid position and leave some adjustment. Even the dyno jet needle ends up being in the next to richest spot with just a K&N and an end cap. Every other carb Mikuni has built in the past has had multiple needle and nozzle combinations.
