Sheared flywheel key
I do most of my own basic wrenching, but after my wee-strom meets SUV incident in the fall, the bike was in at a shop in Barrie getting the plastics and other bits repaired. For convenience I asked them to do a spring tune up, check up and lube everything as well, as the crash had precluded me from doing it myself.
When I picked it up a couple of weeks ago they charged me for repairing a sheared flywheel key. As I said, I do most of my own work on the bike but there are places I haven't really looked into, and the flywheel is one of those places. A flywheel is one of those things that I know is in there, but only vaguely conceptually. I sometimes think I know what it does, but I probably wouldn't know one if I saw one. And when I mentioned this to my tech-savvy, former DL650 owner, riding friend, he was a little surprised, and suggested "keys" for flywheels are something you find on small, low rev engines, not on a larger higher-revving engine which would need something more robust. While I'm quite sure he'd know a flywheel if he saw one, I don't think he'd been into his DL's engine in that way while he owned it.
Wondering about this further, I opened up my electronic copy of the shop manual and searched "flywheel" and "flywheel key". Funny - "flywheel" doesn't generate a hit, leading me to suspect it is a term of art and there is a proper technical name for it that is used in the manual.
So, I still don't know and I'm wondering what it is, where it is, and whether the shop just charged me for something that's not really there.
This isn't critical, as they didn't charge me much for whatever they did or didn't do, I'd just like to know.
