I have a 2007 M109R, and a couple of times I was getting on the freeway, hard on the throttle, shifting firm, but not super quick. I shift into third, full twist of the throttle, it starts to dig, then pops out like it is in neutral. Pull clutch, shift into 2nd, all is good, shift back into third, pulls good. It has done it twice in the last month.
I have owned a bunch of 80's metric bikes, so I have had my fair share of popping out of second on some abused bikes. But I have never had third go out like this. Is this a weak link I haven't heard about?
