Many thanks to Stefan Gratz for these excellent shots.
In 1978 Mototrans, Joaquin Fargas raced at Mountjuic with a 860 ccm bevel B. Grau / V. Palomo. The crank cases were from the same batch of the Mike Hailwood IOM TT 78 engine with close engine numbers. To adapt a electronic Bosch ignition plate G. Pedretti cut and welded the original crank to modify (No. 38) for adaption. In 1979 B. Grau together with S. Canellas started with a 950 ccm with a completely new and Bosch adapted engine casting (No.20). Please find some pics of both bikes at the Bikers Classic 2019 Spa Franchorchamps.
