Vader BD125-10 Gearshift Linkage?

[zburns]

I've got a Vader that literally has 5 miles on it and it's having shifting problems. Doesn't seem to get into neutral and doesn't shift gears right. Sounds and feels "crunchy" too. So I put it up on the stand and am asking for advice on where to start. I believe it to be gearshift linkage and wondering if anybody has a link to possible parts if I crack it open and need to fix. Are CRF50 parts compatbile also?

Thanks!
