4" Kanaflex install on an 04 RXP
The previous owner had installed an R&D intake system and had left the factory ducting in the hull. The R&D system uses the factory hose from the intake to the supercharger and re routes it from the supercharger up to the R&D intake tube. To do this it makes some funky bends that restrict the hose unless you are carefull with the install. I decide to remove the R&D and try the 4" Kanaflex.
I got the supercharger adaptor from the GH store and sourced the duct locally along with some really nice all stainless Mikalor hose clamps, I liked these clamps so much that when I did the Riva rear exhaust I replaced all of the standard hose clamps on the exhaust and intake with the Mikalor clamps.
First step was to remove the R&D intake then remove the seat and cowling for access. Next step was to remove the factory ducting along the right side of the motor and gas tank. On mine the previous owner had left the breather tube connected to the intake so it made quite the mess as all the accumulated crankcase goo was in the intake which then ended up in the hull. I ride salt quite a bit so I liked the idea of leaving the crankcase vent connected to the intake so I found 3" schedule 40 PVC couplings have an OD of 4" that will fit nicely in the 4" Kanaflex. The factory intake has a rubber hose connector that can be removed and reinstalled into a PVC coupling with a hole drilled in it with a step bit. This basically copies the factory crankcase breather system and gives the breather tube a nice solid connection into the Kanaflex. I routed the Kanaflex down the side of the gas tank under the tank straps then used another 4" PVC coupling to connect to a 4" Spectre air filter. I installed the filter more to protect the intake system from accidentally injesting something vs filtering the intake air. These filters can be found on Ebay for about $35.00.

a fizzle catch can would be a better choice.. the catch can gathers then burns off excess.. instead of flowing back into the intake system

Not sure what you mean by "burns off excess" I understood the catch can catches and vents but does not get rid of the blowby as you have to drain the can periodically.
Mods are in sig I'll probably get a Solas 14/19 over the winter then maybe an X charger and injectors and I'm done.

youll want a 15/20 instead of that 14/19 for the future... you will turn a 15/20 no problem

15/20 now .... I'd run a etech 127 in your charger over an x charger .. But an x charger if you plan on going with bigger boost in the future
