carbs stumbles on takeoff

[Guest]

Mate I've got a similiar setup, except for a foam uni-filter rather than K&N. Sounds like you're way too rich all over to me.

As a reference, I'm running 15 pilots, 107.5 main and same needle as you in the middle position (1 notch richer than stock). Fuel screw at 1.25 turns and air at 2 works best for me. I guess you'd go a little richer than this across the board, but the settings you're talking about seem too much.

Btw I found jetting wasn't much different going from from 750 to 850 and I drove myself crazy assuming it would be till I went back to what I started with.

Some good info there.
