Hi i found a old 1980s suzuki 85 2 stroke i think the model is dsx . I got it running but the thing seems to be stuck in 5th gear clutch works and everything just wont shift at all . The shifter srill has a little play so not sure what the issue is. It will spin the back tire without any noise coming from the tranny to so i dont think anything has broken off in there. If anyone has any idea please let me know thank you .
