Has anyone tried different size pilot jets in these carbs?
On setting up the carbs, I’ve done a LOT of research. Mikuni states that the ‘normal’ setting of the mixture screw is 1/4 to 3 1/2 turns. Most of my settings are greater than that! The information states that if its less than 1/4 turn open either the pilot jet is too big or the air jet is too small. If its over the 3 1/2 turns either the pilot is too small or the air jet is too big. Being that the air jets are not replaceable in the carbs, our only choice is to increase the pilot jets. Another interesting point is that increasing the pilot jet causes it to run richer at zero + throttle position. Reducing the air jet causes it to run richer at the 1/8 – throttle position. I just ordered some #45 pilot jets, the Mikuni part number is N100.606-(size) eg 45. I located these at dalesjetsports.com The phone # to place an order (no on line ) 972-530-6768. They were $3.65 each $21.90 plus .39 S&H (USPS) for a total of $22.90. They list pilot size from #30 through #160 so there should be a size
