hey clod, just lookin back at the pics, you don't have the nut on that comes with the strobe sprong kit, how tight was your slipper, and how did you do it up tight enough?
also did you use the stock slipper plates with the strobe?
nope - there weren't enough threads exposed to put the nut on. i hand-tightened the sprong, and it went as far as i could tighten it - i had punch control set low on my MM, and if i hit the throttle hard i could tell the strobe was slipping a bit, but i didn't want to take a wrench to the sprong and risk damaging it. it seemed to work ok as it only had a little slip here and there.
the strobe uses special friction pads, so the stock plates aren't used.
