Ran into a problem with the Givi bars. There's two little metal couplers or dowels that hold the two halves aligned, one in front and one in rear. The front one was loose, despite proper torquing and the resulting racket sounded like the damn engine had a high RPM rod knock. Not good. Here's the little dowel/coupler in question:
It's the gray bevelled piece between the two gray horizontal pipes. Sorry about the focus but I couldn't get a better shot. Anyway, the two bars weren't coming together closely enough to hold the dowel in place and it was just rattling back and forth. Well, the bars are held together by a bolt that passes through two flanges that are held apart by a spacer.
That spacer turned out to be too long for this install, so a quick pass with a die grinder, some paint and a reinstall solved the problem quickly. No more rattle.
While I was at it this weekend, I installed this
signal trigger - the 919 has enough ferrous metal to trip the majority of traffic signals, but it seems to be marginal on some others. I bought the 'new' Green Light Trigger HP and fitted it to the left crash bar. The zip tie is temporary until the provided structural adhesive cures.
You can get one of these for $30 from the manufacturer or between $20-30 from your local Tucker-Rocky affiliated shop. The manufacturer claims a 95% success rate at tripping light sensor loops; they also give a fairly interesting argument as to why it's better than
just slapping cheap neodymium magnets on your bike (which, it must be said, also do work, but I have found they don't always work real well.)
