Krannie, Where can I get those thread in hand guard inserts? They are exactly what I'm looking for! Thanks!
As JDL said, Promoto Billet/Fastway.
There are several companies that make Nylon ones too.
Oh, and I cheated.
Those are YZ250F parts shown there......
Don't those springs look a little small to you.....?

If the piston really is that small, then odds on the cylinder is gonna be oversize (and you've already noted the marks where the rings stop at TDC & BDC) so a hone will do nothing to improve the clearance issue, and you need a re-plate and hone back into service limits
All of the cross hatching is still visible, everywhere.

Any tricks to getting out the swing arm axle that goes thru the frame? Mine would not budge and I did not want to ruin the threads on the end.
If you have never removed it before, it might be tough to get out, with all that corrosion.
I always re-grease everything when I buy it, new or used, so I don't usually have a problem.
Unfortunately, brute force and a torch might be your only solution.
Double nut the end of the swingarm axle before pounding on it.

Also, using a good penetrating oil the night before removal might help loosen things up. I prefer PB Blaster.
Oh yeah, that stuff is good. Don't get it on paint or your hands. It will melt a finger....

Head, after glass beading and before seat grinding
New piston, rings, wristpin

The oil that was drained from the crankcase was highly contiminated, very low on oil, and full of metal...........
We got less than 17oz of oil from the motor........
This would explain A LOT about the pre-mature wear of the piston, the near-siezing of the wrist pin, and the very stiff shifting.
Hopefully , the crank, shift drum and shift forks are not in too bad of shape.

The skid plate was removed so the timing chain could be accessed, and replaced; then the motor goes back together.
YZ fork with the very trick triple clamps!
Diverse Racing rear spring
Oh, and the part I kind of forgot about since I bought the bike: Tagasako Excel Pro hubs, and Exel HD spokes, front and rear (they need a bath, huh...)
