I have been involved in flat track for a long time. And my building bikes/engines started with this engine.
It was raced by a friend. He took a chance on me helping him no one else wanted to deal with his temper. It was well known. Somehow, I survived.
Dan got his transfer points racing, and the Bul was forgotten. After he passed way too young (RIP Dan), I ended up with the bike in pieces. The frame is already done, now the engine is ready to go back into the frame for the first time in 40+ years.
Champion frame, 350cc Bultaco Astro motor. Not the better known 360, this is the earlier engine. And it has a bunch of NOS parts in it.
Looking forward to getting this one done
