Had carb icing on a Triumph TR7, going down the motorway doing about 70ish mph, the throttle jammed open. Fortunately not far from the services so managed to give it a load of brake and dab clutch until clear of motorway. As i coasted to a stop it cleared. It was an early version of the car, did not have the hot/cold valve on air box, so routed the inlet trunking to the exhaust manifold.
Also have a Kawasaki gpz900, when bought it was 15 years old, but Kawasaki still honoured a call back to replace the carbs. with ones with built in hot water circulation to prevent carb icing. Apparently there had been cases or carb. icing, reducng power and locking up the back wheel.
Also read somewhere for every gallon of fuel burnt 8 gallons of water produced? I'm assuming from condensation from the air drawn through the engine.
