MISCELLANEOUS INFORMATION ABOUT YOUR BIKE’S JETTING SETUP:
Spent the weekend trying out various main jets after pulling the airbox (first attempt tuning). Honestly can't tell much difference between 106-110 mains (pulls pretty hard and consistently from about 6k to redline) so went with the 108, but feel like I lost a little top speed when I pulled the airbox, so may need to step back up to 110s. Had DJ100 mains in before the airbox delete. Agree that the bike is considerably louder when accelerating hard, but getting to like it so long as I've got my plugs in.

With needles @ 3rd from top: Bike seems to be more stable from a dead stop after tuning the mixture screws (bogs less), but it still seems to drop the acceleration ball a bit so think I may need to lean the needles a bit yet.

Edit: With needles @ 4th from top: Bike seems happier, but still hesitates from a dead stop with lots of throttle. However the rpms are only dropping a hair and it's not bad at all. Still seems to surge when going from idle to on throttle, but suspect that's just the machine at work.
