You will be better served if you use the SE Ventilator Extreme Air Cleaner. The SE Ventilator Air Cleaner you have on order is really intended for M8 107 Engines that will only do a Stage 1 Upgrade. The M8 114 Engine on the FXLRS with Bassini 2 into 1 Road Rage pipes needs more air to perform up to its potential. WARNING: The Extreme Ventilator REQUIRES a cover plate (Part Number 61300994) to complete the installation.You will also PROBABLY need a new tune. Since you are in the UK, you should also get the rain cover for the Extreme Ventilator that doesn't come with it.

Reason: added information
If you're only doing a stage 1, then you have no need for the Ventilator Extreme. The Ventilator has been proven to support up to 125 hp. If you're going to a 131 kit with an aftermarket cam, that's when you would need the Ventilator Extreme. It's rated to support up to (I think) 150 hp.
For just stage 1 yeah just swap the filter to the SE KN Filter. Done.
That Extreme ventilator is for big bore high horsepower builds. Moonshine HD uses it for their monster 150hp+ builds.
The standard 114 with the KN filter supports engines up to around 120HP~125HP. No need for the big vent until you're doing 120hp+ builds.
Either one of those air filters will work for pretty much anything that you may want to do to the bikes engine in the future if you choose to go that route.
With the stock Ventilator I found several filter element choices: Stock, K&N stock replacement, K&N E-3988 and the STFU kit. Oh, and the Extreme Ventilator (not pictured).
Running this one now with the 131", supposed to flow the most for a SE air cleaner.
