Dropping the needles leans off the partial opening, but does the same for everything greater as well. The engine goes *very* lean at wider throttle openings when the needles are at their lowest, but still not quite lean enough at a crack off closed. I have tried virtually every combination of 3 different slide sets, needles (including a brand new set from Canada), and emulsion tubes. It's an 836 with Yoshimura cam and a Transac 4->1 exhaust. All this work (except the Transac) was done before I bought the bike. Regards, Phill
