Hi Flamegirl; I am a new rider. I am having this same issue. Was wondering what the dealer said or decided.
The other day I must have missed 2nd gear and ended up in neutral 7 or 8 times on a short ride. A friend of mine said I was not shifting it all the way up but that was not the case as I was very conscious of this when it happened on this ride.
I had read about the fat foot thing before but this is not the case either as I get my foot completely out of the way.
I have found that if I shift it slowly and gently it goes into second fine almost every time. (Last night only missed second once. In fifty mile ride.) It is like if I through it up quickly and release it quickly it bounces into neutral. Is that possible? But if I put it up gently and release it gently it goes into gear.
I have never missed any of the other gears no matter what I do.
