So I just sold my 2014 yamaha vstar to a buddy that has never been on a motorcycle. His second day on it I stopped in to go on a ride. He didn't want to ride with me cause he kills it and didn't wanna be embarrassed but I talked him into it. He is having an issue downshifting to first when coming to a stop. I watched it happen, it's like the shifter just won't click down. If he stops and rolls it backwards it will then downshift. I NEVER had this problem and it's not every time, just about 50% of the time. I'm wondering if he might have messed something up downshifting into first at too high of speed and not rev matching? Any ideas?
