A great sport. Love the mines

Hasn't changed much in 30 yrs ! weather still the same, Used to compete here with the lightweight MCC

did you have any porting done or was it done (port timming standard ?).

The 500 should be v/quick ,starter rollers needed then?? I hope to have mine finished for our first race in April, not looking forward to the RH gear change

sounds sharp on the exhaust i have the 500 griffon they recon it sounds the same but deeper note uses a 91mm piston !

lovely ! i have 4 griffon 380,s
