So, pulled airbox, added Factory Pro stage 3 jet kit. I installed 112 mains, left stock 38 pilot jet in, set mixture screws to 2.5 out, and added 3 washers to needle at 3rd clip. Couple quick questions:

-I placed e-clip in 3rd position as instructed by Factory Pro. They recommended 3 washers also to start. I placed these washers on top of e-clip, closest to the blunt end of needle. Is that correct? I recall reading on Factory Pro document this prevents needle bounce?
-having a slight hesitation between idle and 4k rpm, at 4k it grabs and takes off rather well thru redline. Would this be an indicator of needing to go higher on needle position, or idle mix screws?

Thanks!
