--------------------------------------------------------------------------------

I've got a bog when cracking throttle on bike stand. Main jet 172, pilot jet 42, not sure on leak jet, air screw 1-1/2 turns and the Mercer Racing adjustable leak jet 1 turn. I made it a little better, but still has slight bog. Main jet was 170, pilot 42, air screw 2 turns and 1/2 turn on leak jet.

Hi

Well know fault, happens to them all. I would only be concerned if it happens on the track. To rectify most people buy the boysen quick shot.

Since changing jettting we haven't tried on track yet. So hopefully this will fix problem.
