Track weekend Sviesta track in Sweden 2021. I restored this bike years ago. Its a sweet little tiddler. Fast and light. It was raced in the early seventis.
Watching your video brought back happy memories of when I used to race my air cooled AS1/3 in the 70's. Later welding a water cooling jacket round the top half of the cylinders gave little to no improvement in performance but made a lot of work.
Magique se bicylindre, s'était du moto plat en compte tour 🤩, pour avoir une 250tz café racer 1984 avec un montage 1985, haut moteur Humels, piston wiseco, dommage fragile comme du verre 💕💕
Push? Well, I don’t believe this was a race but a track day/practice. Secondly, there appears to be oil/oil dry on the track(probably from the smoking 4-stroke that was somehow let on the track. Thirdly, most would not want to destroy a difficult to replace bike or even the motor by pushing it hard just for bragging rights. I’ve priced spares for mine and that’s a no-go. I won’t mention our aging bodies vs. healing time and ability. Not criticizing but I get nervous thinking about being next to those $800 trashed stunt bikes that might care more about bragging than the spirit of vintage racing. That’s one of the main things keeping me from track days.
