Well, my 07 SM is currently set up with the BC ABEK & long TORS, & no internal mods.
When I bought the bike earler this year I was time-challenged so I let the dealer do the install & tuning. They set it up with 145 mains, 42 pilots, stock needles & 2 shims, screws 2.5 turns out. With that setup by my butt dyno it was clearly rich down low, & lean on top, but with no decel popping anywhere. Bottom line is it wasn't right, & from my perspective far from optimal. It still ran well, but I knew it could do better with proper tuning.
It is now running 155 mains, 42 pilots, stock needles with no shims, & screws less than 1 turn out. It feels pretty good everywhere by my butt dyno. With the current setup it is probably a touch rich at idle. The mains are probably within 1 size of optimal. Mid range is responsive & it pulls strong.
I have the Kawi CV slide springs on order & those will go in once I'm otherwise satisfied that the jets & air screws are as good as they are going to get.
When my butt dyno is satisfied then it will go to a real dyno for confirmation, & at that I'm most interested in the A/F readings.
Given the above info, what do you think of trying 40 pilot jets & backing out the air screws?
