My riding will move in reverse but will not in forward. The higher speed selection the louder the noise; the noise is almost like a metal chatter. I have replaced the transmission belt (upper drive belt). I have taken the transmission apart and could see no visible indications of bad pieces. I can turn the gears by hand when the transmission is out. 
If my lower drive belt (goes to engine) is bad and needs replaced, would I still be able to go in reverse? I would expect my reverse to be out also not just forward. 


All 3 positions fully engage by hand. If in the forward position wheels are locked and will not roll. In the neutral position, wheels are not locked and can push. In the reverse position, wheels are locked and it will engage on its own. The only problem I have is getting it to move forward. I currently have transmission out and the collar has very, very, very slightly beveled edges. If I had to guess, the collar does not look like the problem.

I would check the shift fork to see if it's bent,looking at your pictures I can see the rounded edges on the shifter clutch's (that's what we called them on old Harleys) once they lose the sharp edge they will push them self's apart if the shift fork is not engaging  them fully and the noise your hearing is probably them bouncing off each other.If you can get them to engage  fully I think the problem would go away. you might be able to shim the side gear in to get full engagement.

I am not familiar with your machine but other members may have a better idea.

I've always called them a dog clutch, They are used in the transmissions of outboard engines, among other things. I suspect the linkage is out of adjustment, and are not letting them engage properly. As Bill said, since I'm not familiar with the machine, I can't say for sure.
