So guys i need some help my dad and i had to replace the case in my kx. And some of the gears had fallen off when we transfered over the tranny, We believe we've gotten all the gears in the right order they all rolled smoothly together like they should. We got the engine back in the bike it ran fine but it only goes into first second and third there is no forth through sixth,can anyone tell me if possibly the gears have gotten mixed up or something is getting caught up so it wont shift any higher than 3rd.
