OK, so maybe my ebaying is getting a little bit outta hand... I just bought a set of 38mm "slingshot" carbs from a `90 750(or so the seller says - they look like it) has anyone else put these on an otherwise stock 1127 motor and how did it work out? I've got my 36mm's dialed-in pretty good with the dual filters (wasn't easy) and I don't wanna go spend a day fiddling around with it if it's not gonna change anything noticeable on the bike. For reference, I am making *p-l-e-n-t-y* of low down and mid-rpm torque and I don't mind giving a little up if it means I can see a big increase (5HP or more) on top. I see that factory-pro makes a jet-kit for doing this exact mod. Anyone used it? numbers, suggestions, anyone?
