potting (encasing everything in epoxy) should take care of all that....and the wires vibrating, well, then everything should be rubber mounted. I think of all the bikes with the R/R mounted on the front of the bike, right in line of splashing, so I don't think that's a concern, either. I wonder if it had something to do with noise, the fins vibrating at an engine harmonic? Not really important, but I noticedwhen I replaced the mounting plate with an aluminum plate yesterday, for a better heatsink. If it rains today, it's the ziptie quick throttle mod....happy winter modding, everyone.
