I had a similar experience just recently. 2300 miles on the bike, full synthetic Ams oil in the gear box, end of a truly vigorous ride where redline had been visited regularly tween curves, and during decel downshifting, the pulse was accompanied by nasty low cycle grinding sound.
What happened is the gear box had dropped into neutral, due I am thinking to light pressure on the lever caused by my inattention and my new shoes; upon discovering this I clutched and tried to continue going down to 1st gear while still breaking hard. That's when it refused to go and "kicked back". I cursed myself and tried to upshift into second still (braking)dropping speed; the same effect ensued; wouldn't engage second either. Gears were simply not meshing and the lever "pulsed" back at me.
After slowing to a crawl, maybe 30 mph, I again tried to clutch and get second; note the engine was not idling as I had the clutch disengaged fully and was blipping the engine trying to find a semi-compatable match. Gearbox at first resisted slightly and then clunked into second VERY hard.
I had the shop check it out for me the next day while they were spooning on new rubber , Pilot Road 3's. They reported that the engagement lever was acting through a normal throw and that the transmission was strong enough to take my regrettable incident of unskillfulness. I'm chalking it up to pilot error(s) for now and blame my inattention partly on how well the tranny shifts most of the time. But it is interesting to note the similarities in our experiences and I will be mindful of making sharp and timely shifts in the future.
Didn't care for that experience at all and wonder if it might be partially heat related coming as it did at the end of an hours vigorous riding? Something I will be watching for in the future. Don't want to take the bevel off those polished gears if I can help it.
