Does anyone know what's the problem when 2nd gear jerks at 4rpm or higher? I've seen some very old posts about it, but couldn't find a post of someone finding the problem or getting it fixed
Doe this only happen under hard acceleration? And only in 2nd gear? If so, that is the beginning symptom of the dreaded second gear failure. Trust me, I know. Was in the same situation as you are, and it only gets worse :-(
I bought a 2009 last summer with 17000 on it. It started jumping in 2nd like the clutch slipped, then grabbed. No it is jumping into neutral even if I hold my foot under the shift lever. Looks like a costly repair since the engine had to be dropped. Bought this from a reputable bike shop.
