I posted this on IA but thought I would share. This last week I removed the PAIR valve using Mocc's kit. Wow, what a difference! The bike actually runs different. I noticed it won't run as well if I try to run with the choke out a bit Like I could before. But it warms up quicker. Of course, I can feel the bike is actually lighter than it was before and it leans a bit to the right now with that big air box on its right side :lol:
