I began this build in January and finished this past May. Although it wasn't the best bike of that year in the 125 class, I chose it because I rode a 1991 YZ250 in my teens and really enjoyed that bike. Although roached out, everything was in good, restorable, condition. Frame wasn't dented or bent, motor was strong, wheels were in solid shape, stock pipe and silencer in good shape, etc.

It now resides in my living room as a conversation piece.

Nice! Where did you buy the graphics and seat cover? They look very similar to oem.
I have a bike waiting. I'm thinking of doing a resto mod with a 96-01 engine and front end. Need to estimate the level of difficulty first though.

I got the seat cover off of ebay and the decals from here: https://yzdecals.afegraphics.com/~afegraph/yzdecals/view_product.php?ad…

Thanks! I used aircraft remover and a wire brush to remove the old paint. Repainted with factory Yamaha epoxy paint. Cylinder is unpainted.

Hey man. Can you do me a real.big favor?

Can you hold your phone sideways and take a real.hood, stable, focused clean picture of that deltabox decal on your swingarm? Get it in tight so the logo takes up the whole jpeg.

Thanks

Great job also. Very well done.
Did you shoot the Yamaha epoxy yourself? The motor like the rest of the bike looks super clean.
I love the metallic in that paint.
Thankfully you can still find replacement parts for these. Best of all they tend to in-expensive.

I am sure there are aftermarket kits out there. On rebuild I found a once over NOS piston and installed based on the cylinder wear.

These are UFO plastics, Clarke tank and a seat cover off of ebay. Factory exhaust that was on the bike already.

Thanks! I painted it myself. Ordered the paint in a can on-line. The hardest part to find was the front sprocket guard. Came from Italy and was $100.

Hey I know I’m late to this post, but what kind of paint did you use?

For the engine paint I used factory Yamaha silver epoxy paint.  I may still have that around somewhere.

Is the seat cover red or the magenta. I have a 91 I am building and I want to go with a red seat cover. Not sure what years are the same for seat covers.

Magenta on mine.  I wanted as close to showroom as I could get for the year.
