Ok, next time I remove, Y gate, and reposition the fuel tank on the back seat frame to sync the carbs, I will have to take a look at that. I suppose if you were not going to do an air box mod, you could just shim forgo re-jetting. But frankly other then the fact that you get better response repositioning the jet needle, avoiding an airbox mod and the almost mandatory re-jetting that go's with it, is a lost opportunity to unlock where the final bit of stock power is hidden.
If you're just shimming the needles, the rack can stay in. The carb tops can be taken off with them in place.
