Hi all I have a Fazer 600 98 model and I'm experiencing poor power output from half or three quarter throttle to full throttle . When I give it full throttle it almost dies totally and feels like its being strangled and the only way to maintain any further acceleration is by feathering the throttle back and forth . Also the bike always struggles to start with the choke on and mostly I have to use no choke and just use a few attempts if starting by using the throttle to get it started from cold ( hot starts are ok ) when it starts from cold it very often cuts out until it is warm. When I am riding it and I have been accelerating , when I throttle off , very often the bike back fires on over run. The intake rubbers are showing signs of external cracks but I haven't taken them off to examine if cracks go through to inside. Air filter has previously been cleaned but as long as i have owned it I don't think it has been replaced. Also the bike foes just over 100 miles to a tank of fuel , so not very economical , probably doing about 25-30 mpg. Bike really struggles to go faster than 100 mph too. Does any one have any ideas.
