So here's yet another sound question, but I don't have a recording of it yet. I've just started to notice when I start the bike in the morning there is the normal startup, but as soon as the engine catches the I let off the start button there is a "left over' sound, like a spring unwinding or something is the best I can describe it. It is a quick sound, easy to miss, and like I said it happens right after I let go of the button. I'm guessing the starter clutch or flywheel, but is this an engine out, don't use it until its fixed thing? I don't really know what could be wrong inside there, I put new springs and rollers in 2 years ago when I replaced the tensioner and chain.
I'd keep riding, business as usual, and not worry about the starting noise as it is subtle and short. Of course if it gets loud and long and bike has trouble starting, that's a entirely different thing.
