Hi. I am driving a -99, but if your machine doesn't go well from 3/4 to full throttle, it is an indication that the main jet is too rich; have you modified the airbox? The snorkel on the newer KLEs (including mine) are too small to work well with the bigger jets, so if you are going to use them; you will need "more air" to compensate for the bigger main jets (but that will also affect the air/fuel ratio everywhere else, which could mean that it could go lean in normal riding (which is usually affected by the needles)). Getting this dialed in correctly can be hard, since there are many factors that can effect this (which is why I will just get two similar needles from the older kle (N96J), as that will probably make the "balance" well too.

Edit: The change from 92, 95 too 100, 100 did actually make a difference, but going from 100, 100 to 110, 110 did have a really nice effect on the performance. B.T.W. do you have two identical needles (N60D) or two different needles (N96L and N60D)?

Edit2: An extra tip: if you want to get things dialed in correctly with your current needles and the 112 main jets, it could require some time, because even if you get the machine to run well at full throttle, the transition between the needle and the jet could still not be well. If you are lucky, shimming could fix this, but the length of the needle is not the only factor that comes into play when getting the needles to work well. There are more things, like taper and the diameter of the needle; will they be correct when you are using 112 main jets with N60D needles shimmed? Who knows, you could get it all correct.
