have you got aftermarket oil breather eg bailey ? only the original oil breather does this because it vents the oil vapour to the airbox and when you take the oil cap off it lets air in

If it doesn't cut out:
It either has worn rings/bores creating a lot of blow-by, meaning that air is not leaked in from the cap, but rather exhaust is leaked out.
Or it just runs really rich, so when it goes leaner because of the leak, its just spot on.
