Exhaust smell?

[keno]

Bike has been smelling of exhaust fumes quite strong lately took oil filler cap off and it stinks of exhaust gases.
Bike runs fine and i have checked the crankcase breathers and all is clear.
Any suggestions appreciated.

Bikes not running very rich is it? Take it the oil levels are constant and you're not getting petrol leaking into your oil?
