Hi, my new to me 1993 900ss has a pair of Keihin FCR41 carbs fitted. I need to adjust the accelerator pump timing as it's coming in a bit late. All I can see online is how to adjust it with the screw on the single FCR carbs. I don't have an adjustment screw on my linkage, is there a way to adjust it?

I think the only adjustment is to bend the little fork-shaped end of the lever so that it activates more or less onto the plastic pivot that pushes the plunger - can't find the manual for mine ATM but I recall reading that in it.

Thanks Dukedesmo! Seems obvious now. I’ll give that a try later on.
