My ´94 CB1000 recently out of the blue started to stall. The idle surges & it will take no throttle. I´ve taken the carbs out & apart & there didn´t seem to be any problem there. I called a dealer & he said that it was an air leak so I tore the bike apart again to get to the airbox. I re-siliconed the rubber air tubes at the airbox end, replaced the air filter & put the bike back together & still the same problem. Also replaced the spark plugs & changed the gas. No luck there either. I´m stumped. Any advise? DAS
