Ok, the reason I asked where the vehicle starts to move is I wanted to make sure you were disengaging the clutch. Sounds like you are. Now, with the mileage you have, a new clutch is probably a good thing...

But, I would say you will have to take the trans to the trans guy you know, and most likely, the blocking rings are worn out. Not to mention some normal wear, and end play. The blocking rings are the brass rings with a taper inside. When you push on the shift handle, this applies pressure to the blocking rings, and stops the main shaft from spinning, allowing you to go into gear without grinding.

Once you get the trans there, I'm sure he will check out the shift forks also.
BTW, I used to do the tanks also. The 88's were my favorite ones...
ah o, site messing up ...

Down all day yesterday, up today, shit or get off the pot.
Where is everybody?
