Hiya,

If I fit a k&n filter / Mac twin cans to an otherwise standard bike, will it cause fueling issues?

Thanks for any info.

You shouldn't have a problem with a K&N replacement element and cans. I would keep the snorkel in place for now though.

Any further changes to the intake will require fuelling alterations.

TBH, to get any real performance benefit out of the K&N and exhaust setup a fuelling device would need to be installed. Even on a totally stock bike there are a few hp to be had by adjusting the fuelling.

Sorry mrP....what's the snorkel?

It's the rubber 'periscope' that sits on top of the air box.
