Anyone have phf carbs on paso

[muxey]

I need to know what pilot jet size I have 65 but feel its weak any ideas ?

I have 36mm PHFs on mine. Years ago I did a lot of testing at idle and small throttle openings, and settled on a 60 in one carb and a 65 in the other. Can't remember which went in which carb, I'm afraid, but my bike has started and run great ever since.

Hi thanks, I have 65 in both but its very lumpy up to 3500 rpm
it also spits back on idle sometimes I figured i need larger jets ?
I hace checked all the outher obvious causes,
Any outher sugestions ?

... and thinking back to the tuning and testing I did, over many hours and days with detailed record-keeping, I believe I found the correct pilot jet and throttle stop adjustments (each which affects the other) right to within 1/4 turn of the screws on each carb (each of which affects the other) and then the carbs synchronised to within 1mm of slide movement.

I believe that is the sort of accuracy required for optimum performance.

If you then get the right chain adjustment, and the right ignition timing (both of which I do by the seat of my pants) you can have a very responsive, smooth, and fast bike.
