at running temperature of 104c, fan cuts in to cool but causes the bike to stall when at standstill and on tick over speed of about 1200revs. The only way I have been able to overcome it stalling is by opening up the throttle to increase the engine revs slightly at the point that the fan cuts in.This though is a hit or miss solution that does not fix the fundamental cause of the problem. HELP URGENTLY REQUIRED, otherwise she is a great bike.
