[QUOTE="whenfoxforks-ruled, post: 1207644, member: 73147"] Any fcr carb,yes they all have the same issues,07 and newer may be different!Get the jetting,timing and valves in spec and it is an indestructible machine(except for the snapped rods thing). Response is best felt with quality fuel,mtbe based fuels deliver! The 70 is what I settled on for a mid temp baseline,I believe the pilot went a couple smaller and the main one,needle 2nd from top.The popping and bogging gone,that bike can get up,unbelievable! The diaphragm mod,I do not know exactly where its going,increase the ap squirt and to what extent,the burst of raw fuel just clears the slide,its to help the off idle transition,not dump a half a bowl of raw fuel in and out to burn in the header!The ap adjuster,if you watch it,it floats,hesitates and sometimes does not squirt. The o ring mod takes care of that,if you wire it solid the arm bottoms out,that is where I thought grinding the diaphragm came from,but the o ring lets it stretch. Jd's multi taper needles seem the next ticket! [/QUOTE]
