Cam Cover Blow Out
« on: August 01, 2019, 09:37:26 AM »

Sitting at the traffic lights, engine idling, I heard a slight  'puff'  and the engine stopped.  Started it up again, but a few minutes later I could smell hot oil..& pulled over.  The problem was one of the 'plugs' of the cam cover gasket had blown outwards, causing oil to blow out the side.

Simply loosened the cam over bolts, pushed the 'plug' back in, & carried on home where I cleaned the oil off the bike.  I then got on it & went for a 10 minute ride, red-lining it in the lower gears several times........with no blow out.   Any ideas why the blow out happened at idle??

The photo shows the plug after put it back in place.

I would check the vent hose to the air box, it may be kinked.
