Well I installed the kit today and with the nasty weather I have only taken the bike around the block, but I must say it shifts beautifully, much smoother than before and the clutch has a good smother pull. Of course I will admit while the hub was accessible some extra holes were drilled according to Hondaman's mod so either the kit or the holes helped, probably a little of both. Now in reference to the noise or rattle, I would say a fair estimate is about a 40% reduction, it is still there, just not as much volume. My biggest complaint about the kit is total lack of directions, you get a photo showing the line up the discs and plates. I am by no stretch of the imagination a seasoned mechanic, it would be helpful to just have the full procedure in writing. I did have the advantage of having installed a few overall's in the past and had a little prior knowledge to fall back on. For example, soaking the discs, sharp edges of the metal plates facing in the same direction, which direction the the taps and washers go in assembly. Some shots are attached and I know the key question from folks reading this thread, would I recommend the kit, I want to put a few more miles on before going all in, but with just the short spin so far there is an improvement. Damn, I might have a future in politics.

b. My screw chart (This is for the metal screws-at 75 no paper needed for the other kind)
c. Modified lifter plate (I already had the same lifter plate in place as in the kit. Broke the original during an earlier disc replacement.)
d, Lifter plate bearing (Kit only comes with the other bearing, no center, so you have to press out your old one. Again directions needed, I just used my original plate.)
e. Order of discs and plates (You end up with metal to metal at the front and back of the pack, seems weird but works great.)
