hi all my 700r4 has been acting up now about a week with quick shifts ,late shifts and now hard shifting from first to 2nd. feels like i have a shift kit ,but i dont. detent cable has been adjusted and it was shifting good yesterday for a while,but when i went to the store yesterday it started the neck snapping shifts from 1-2. from 2nd it shifts fine,could it be a sticking valve ? im taking it to a shop tomorrow if i'm not working. any ideas thanks.
