hey me again, wanted to run the ongoing saga past you lot before i bite the bullet and lilely pay a huge garage bill!!.. so bike starts runs and rides for 10 15 minutes then the it gradually loses all throttle powel untill it stops then stalls, will start again imediately but cannot generate any accelaration power..so far in a process of elimination i have- replaced the spark plug renewed all the clutch plates bled the front break caliper(seperate issue middle pot wasnt working/releasing). the bike is injection so no carberetta, its been suggested the buke could be running to rich or lean , or the lambda sensor is faulty, given the bike is only worth around £1000 trying to be sensible with repair costs or options
