Brads' must be a Jiri Staric bike being new. He uses later model internals. The blue tank is another clue. Good to see no one worries about a bit of noise either as the racer has the original straight through pipes. My Dads' made it to classic dirt on the weekend and I gave it a start. I can only imagine the amount of noise 30 or 40 of bikes with no mufflers running around the paddock would sound like. I was told there were only 900 made.
Dads' was a real labour of love. The motor was flogged within an inch of it's life, not to mention the motor had been pulled apart with a shifter and a tool box full of screwdrivers. It will get a run when fully sorted.
