Hello. So, I purchased a torn down 78 DT175 and rebuilt it top end to transmission. It had needed a new shift shaft which I replaced, and put it all back together and got it running! I was so proud it was going finally after all that effort. However, it wasn't shifting properly, and I am hoping someone has knowledge on this specific issue.

So in order to shift it you have to kind of jimmy it; for example on the shift up, the shifter would stay up and I'd have to tap it back down before I could shift it up again to the next gear, and visa versa shifting down. So, I currently have it all back apart to assess the issue.

Upon inspecting all the springs and mechanisms per the repair manual, I don't really see any issues; all the springs look good and are properly connected.…

I bought this hodgepodge not even knowing it had a 125MX motor in it..... Not sure what I'll do with it.
