I had to bring the rear up this high to get tension on the NDS up to around 60 kgf, which was enough for me to trust not to go slack under torque. According to all that I've read, these rims should be just fine at that tension, and I wasn't close to stripping any nipples while building. Nor have I had any sever impacts, falls or crashes. I haven't pinch flatted even once on this set, and I weigh 145-150, running 100 psi in my gatorskins consistently. Unless the tension is too high, I can't imagine any other reason for the pulse. At speed it's less of an issue, but really annoying while coming to a stop. The pulses feel like they are at a single spot in each rim, big slow pulses, not multiple (each spoke) pulses. I'd love there to be a solution, but just assumed that it was normal.

This may be of no help, but my crappy RS10 wheels do this too. Just one spot on the rim and worse as I slow. I took it to the lbs and was told it's normal and probably due to the weld seam or however the ends were joined when they were made. I would hope the kinlin rims are better made and don't have that issue, but maybe your rim seam is a bit more apparent.
