Bikermike1 Posted July 29, 2017 Share Posted July 29, 2017 Can anyone help, after a long run when I pull up or come to a junction, pull the clutch in I hear a whoosh noise like a sudden release of air then the engine cuts out, smoke comes from under the tank near the handle bars. The engine will restart and I'm on my way again. Any help is appreciated. Link to comment Share on other sites More sharing options...

Is your bike running normally as far as, fuel economy, acceleration, smoothness and idle.? Engine Temperature Normal? Did this happen just after a service? Does the smoke smell like burning oil? Any flashing error code for your EFI? Is there a possibility your engine oil has been grossly overfilled? Remove your air filter and have a good look at the throttle body area - any pooling of oil?

Bikermike1 Posted July 30, 2017 Author Share Posted July 30, 2017 I've done 1000 miles since the last service, this happened twice and it is when the engine is idling, other than that everything looks and runs as normal. When I get some free time I'll remove the tank and do some investigating. Link to comment Share on other sites More sharing options...

checksix Posted July 30, 2017 Share Posted July 30, 2017 Maybe the fuel tank vent hose is partly crimped or blocked and you're hearing the air as the vacuum in the tank releases? Link to comment Share on other sites More sharing options...

So I've lifted the tank and noticed the air filter housing vents are in the vicinity of where the whoosh noise and smoke came from, I'm no mechanic so forgive me if I am way of the mark but their is a vacuum chamber associated with air filter housing, could this be at fault and causing the whoosh noise?
