This racing season was short for us, only four races. In 2020 we fielded an 880cc rephased XS650. Raised inlet ports, larger valves, 87mm wiseco pistons, and new design cam, ductile iron liners and other parts designed by me. The engine goes well, we had it dyno tested at Richard Albans TTS in Northampton, where we test all our engines. 90hp rear wheel at 7500rpm, and 65lbs/ft torque. Richard congratulated us on building " a very high performance tractor".
This engine isn't even pushing the red line up, it will run happily on super unleaded fuel. It is the culmination of five years of CRMC sidecar racing efforts, last year Steve Mann's bike won the trophy, this year we are in a different class racing bigger engined BMW airheads. As a potential street bike engine, in a lightweight chassis, it would be fun.
Howard ( ex Smedspeed) but still in the game
