While it may seem self-evident to some, my initial method of re-installing my B-TH on my twin presented a problem I spent too many minutes trying to solve. The unit has some wires located about one o'clock that are in direct line with the one bolt used to mount the mag. There are of course two studs that slip into the crankcase with no problem, but the Allen bolt has to snake past the wires atop the mag, and the task becomes frustrating
because the (supplied) long Allen 'wrench' that actually has a screwdriver style handle, is a
ball-end Allen allowing several degrees of offset movement to tighten the bolt. Thus, one
cannot insert the Allen bolt on to the wrench because the round ball on the end of the wrench just won't hold it (straight) very well. So when you try to slip the bolt onto the wrench the bolt flops, then you have to inveigle the floppy bolt past the proud wires and try to get it lined up with the bolt hole, that you surely cannot see without the aid of some well directed light. I've installed the unit in past years and recall the struggle. This time I was unsuccessful for far too long.
It finally dawned on me to "think opposite" as I usually do. So I removed the mag, inserted the bolt into the third hole and held it firmly with the supplied wrench. Then I simply offered the mag to its final position, twisted it ever so slightly, felt the bolt hit the hole, turned the wrench a bit to start it, and Bob's your uncle. I was a little embarrassed
the solution didn't occur to me earlier, so what was previously a royal pain turned out to be an ever-so-simple installation of the Allen bolt.
