I have a 2003 DS650 Baja and i am having problems with it slipping out of 2nd gear. Every other gear is perfectly fine and wont slip out. It tends to slip out of gear a lot easier if the terrain i am riding in is bumpy. I am planning on going on a trip where i will be climbing steep hills and im worried about it slipping out of gear as im climbing up a hill. What do i need to replace or repair on my quad? Please help... Thanks!
