Right now, as my sig says, I'm running SS Pipes, cut out the bottom of the airbox & removed all snorkels and a few other things, 132 mains, 45 pilots, TBS Needles, and I've drilled out ther vacuum port in the carb slides for throttle response.
I haven't checked for lean/rich yet, but it's not quite perfect. My air screws are 3.25 turns out and I'm still getting some popping on decel, and get an occasional light backfire with the popping.
At first I tried the TBS needles with 45 pilots and stock 120 mains because my new mains weren't here yet. It was strong in the low-mid but ran out of breath at the top end (as you would expect with a stock main).
Then my 132's came in and I tried the stock 42 pilots with the 132 mains. It was strong on the upper end but wasn't running well in the low-mid range.
Finally I put in the 45 pilots and now it's running strong from bottom to top, but as I mentioned I have some popping and occasional light backfiring.
I'm getting close. I think the next thing is to check my lean/rich status out and see what the deal is. I think I also need to tweak my air mixture screws a little yet.
I'll report back when I get it more dialed in, but since every bike is different, I think 132-135 mains with 45 pilots is a good starting point. Definitely do the TBS needles - they are cheap and really help out the mid range.
