Quickie question ...

My bike is a c800 k6, fuel injection, lambda sensor.
Can I just fit a k&n air filter, no mods, then, later, an aftermarket exhaust, no mods, or do I need a processor, or some additional add on?

You can fit one or the other with no fuel processor, but when fitting both you need to to add a processor to sort the fuel out.

Thanks Alfie.
