either/or... depending on what you see as the least amount of work to accomplish.

...or you could try backing out the mixture screws with the setup you have now till you get the results you are looking for then count the number of turns that the mixture screw is set at. You can then decide on the pilot jet/clip position at that time.

Make sure the bike is fully warmed up when doing this. I rode mine around w/o the fairings and came home and worked on it when warm/hot.

The idea is to richen up the mixture/pilot circuit, as it does sound like you're a bit lean (or have a vacuum leak), right now.

Before you do, make sure, as others have mentioned, that you're sure all vacuum lines are properly capped and you have no vacuum leaks and that you have proper choke freeplay at the end of the cable down by the carbs.

Also, do yo have a way to sync the carbs? You will need to so that in the near future, if not now, if you have the means.

BTW, the 112.5 mains are most likely a tad rich and you might consider 110s in the future when you start fine tuning your jetting. You do realize you're not over playing w/ the jetting by a long shot, don't you?
