What size jets should I use.

[sandmanmike1]

Just rebuilt top-end and installed boyeson reeds and I am installing a 96 VMAX pipe. Reeds call for 2.5 to 3 sizes lower in main jet. Would pipe off-set this. Also should I keep it rich for awhile with everything being fresh.

usually the more hp u make the bigger the jets i dont know why it sas to go down check your piston wash on your piston (carb side) half moons should be 1/4 by 1/4
if bigger your rich if little or no wash is evident (black cylinders) your lean and it will eventually burn down this test should be done at a full throttle run 3-400 ft and hit the kill switch ull need a benda light to see the pistons tho
