FCR Pilot Jet

Recommended Posts

Hi guys,

I've got a FCR39mx carb on the bike airbox mod which is a bit bigger than 3x3 probably more like 11 square inches.

I have a 155 main jet and the NCYR needle set on position 2.

also I've fitted a flex jet Pilot jet is a 42

Bike runs great pulls like a train no hesitation, but I have to turn the mixture screw out 3 1/2 turns to stop the revs hanging.

I've ordered a 45 pilot jet.

So my question is this the way to go by increasing the pilot jet? and I'm hoping it doesn't affect any other circuits.

Thanks in advance for any replies
