Need help with 61x single carb settings.

[Dustin88]

I have a stock 95 sn with a 61x 701 and stock 44mm carb.

I added a limited b-pipe, factory waterbox and ocean pro spark arrestor.

I now have no bottom end but the mid and top end scream, does anyone have a similar setup and what are your carb settings?

Right now mine is set to FFP suggestions.

Main Jet : 145
Pilot Jet : 120
High speed screw : 12 turns out from closed
Low speed screw : 2 2 turns out from closed
Needle & Seat : Stock
Spring : 95 gram

You are probably too lean in the pilot/popoff and overpropped. Either of these by themselves or combined will cause exactly what you are describing.

I have a stock impeller, should I go to a higher or lower gram pop-off spring? I put the factory pop-off spring and the factory low speed get back it and no real change.

I starts right up. But the motor shakes real bad at idle and up until about 1/4 to 1/3 throttle then it feels like a turbocharger kicks in and it hauls a## up until the redline. I guess i really just dont know how to tell if its too lean or too rich.
