PIPE NOS 1W3

Almost 3 year of searching and finally it has turned up.

Rotor 1w3

No spark is this the trouble? It has a lot of material missing where it has been rubbing against the stator, due to bearing failure. I would expect this is the failure of the electrical system.

Top end assembly With all NOS parts including barrel The top end is A1.
Note the single ring piston on the YZ 250 D . Took quite a wile to procure these items.
Parts available from YAMAHA was the wrist pin the little end roller and the circlips

Barrel NLA Yamaha.
Also note the original green blue barrel base gasket this was from a NOS gasket set Yamaha no longer provide these coloured gaskets. They do have gasket for these bikes however the are all gray which is no use if you are attempting an a grade restoration.

All preparation to the frame work now complete. Now its of the the paint shop for paint preparation. This will entail sand blasting file finishing and filling any stone chips.

This time we are about to do 2 bikes at once. With the similarities of these 2 being close it should prove much faster than one at a time,

Rim identification ???

Here we have a standard factory fitted DID rear rim. This has been removed from a YZ 250 D 1W3. The same rim is fitted to the YZ 400D 1W4. Rim size is 2.15 x 18.
The markings are located on the edge next to the spokes.

Assembly frame.

This item is a must have for the serious restorer.
Once the frame is painted the bike can stay secured on this frame untill the restoration is complete.
Once complete simply remove and bolt on the foot pegs. Im EXCITED
