I know exactly what you are speaking of. After taking off the flimsy plastic handguards and replacing with a set of FRP barkbuster-handguards, the lever bolts stick up above the lever about an inch or so, very scary and perfect for shearing off a nice strip of forearm flesh the first time you head over the bars. I stumped the parts guy at my local Kawasaki dealership with this so this is what we came up with:
We dug through a box of odd bolts and the brake lever bolt we replaced with one from a KX 125 (I think). We couldn't find an out of the box replacement for the clutch lever pivot, so we just cut the top of the original one down and grinded off the sharp edges. This fix would obviously work for both sides.
Take the stock pivot bolts in and explain the situation, they probably have some strays on the shelf.
I haven't had any problems with them since I replaced them and they are much safer.
