I got a 99'gixxer750 and the problem is that the bike's idle would start going crazy after reaching normal temp. The idle wouldn't remain constasnt. So a buddy of mine disconnected the boost sensor (the one slightly above the airbox)and the idle problem was fixed. HOWEVER, now the fi light is on (I know its cuz the sensor was removed)and the bike lost some power. Is the problem the sensor? Air leak? or something else. Please help!!!!
