Max, what is your thoughts on this? I watched/listened to the video a bunch of times last night and just can't tell. On my iPad it sounds like spark arcing. On my MacBook it sounds mechanical. I did look of discharge between wires, etc but didn't see anything.
The pump turning on noise is sure interesting.
Kong, do you have a spark tester lead, something like this: http://www.cdielectronics.com/product/511-9764/ You plug one end into the spark plug cap and the other end clips to ground, OR, remove the clip and plug onto the spark plug. If not you should do what MAX suggests and plug in a spark plug to the plug lead and hold the plug to ground and check for spark and that noise. Personally I would not run the bike with no load on the coil(s). High voltage will look for a ground and can arc in the coil pack or out of it. Seen that on outboards a few times at my friend's shop. He uses the CDI leads I showed. I have some too.
Have you by any chance run the bike in the dark and looked for arcing?
