TWO-STROKE SPOTLIGHT: DAVE HALVERSON’S 1977 YAMAHA YZ250 PROJECT BIKE

The breakdown. 

Hello MXA crew,

Thought you’d like to see this restored 1977 Yamaha YZ400. Bought this from a guy in Lake Elsinore, California, who claims this is the first bike with a “powerband”? Huh? Also he recommended this for expert riders only. Not sure what he was talking about. It looked liked somebody looped it out years ago,​​​​ got scared and rode it part time for 41 years. Anyway, here’s my completed project with the following points:

 How he bought it. 

The bike in pieces.

-First generation long travel bikes
-Untouched K&N NOS with vintage stickers
-Custom J&E silencer with factory Yamaha mount (era specific thanks to T&T in Norco)

Fully restored.
