SX/SXi/SXi Pro Carb Tuning with Coffmans pipe

[Sgtlange]

I need to do some carb tuning this weekend i'm getting some random bogs and the ski just doesn't feel in tune. I was wondering where you are all at with your low and high speed screws? What would be a good starting point? I picked up this ski earlier this year and havn't done any tuning yet. I'm running a coffmans pipe, dual keihin 44's (i think they are 44s not sure how to tell?), aftermarket head running 93 octane, enhancer, advanced timing etc...

Thanks!

The bottom screws are for idle only, tune them rich of peak rpm on the trailer. Open the top screws until power is lost then lean to peak. Clipping one coil off the springs will sufficiently enrich the 1/4-1/2 throttle mixture.
