K & N 3910 Air Filter kit

Just purchased the rk3910 kit for my heritage just wondering if before changing over from stock there is anything special that needs doing. Thanks for helpful tips.

If you have slip on mufflers, you're going to need some additional fuel.

I suggest a TFI if you need fuel.
