Did this issue start all at once or is it something that started getting worst as you rode the bike? Are you the original owner? Any metal debri int he gear box oil? Sounds like a gear has sized to a shaft or engagement dogs worn off or maybe something with the shift forks/drum.

ya, i went to a track and it just hit me. i went trail riding the weekend b4 and it was fine then after about 10 minutes of warming up it wouldn't go into third. i'm going to drain the oil and see if that helps but otherwise idk. thanks tho
