After throwing in the towel and having a shop install my new EMGOs and jets (the previous owner put on TORs), I took a trip to VT with a couple buddies. I'm noticing a couple annoying things about the fuel delivery
1. as opposed to intermittent pop that happened on deceleration/engine braking about 3000 rpms, the bike now sounds like a popcorn popper (or the quiet 4th of july) when I am engine braking.
2. i've noticed that if I quickly open the throttle all the way (90% or more) all at once the engine sputters and pops and I lose speed until until I roll back the throttle to about 60% where it kicks in and starts running strong again.
. . . I'm thinking both of these arise from a too-rich fuel mixture that the shop didn't address when they re-jetted the carbs. What y'all think?
I'm also wondering if I can just location the mixture screwed and back them off a quarter turn or if it's more involved than that.
