Today I took possession of of two dna air filters. I have never followed the stage 1/2/3 thing mainly due to not fully understanding it but also the fact my bike runs great, but anyway, as chance would have it, someone local to me was selling these two.

The main air filter under the seat and the other one that goes on the side, I also have the ring cover thing that goes over the under seat filter.

So, is it just a case of installing both these filters and cover thing and be on my merry way or am I missing anything ??

I don't have a kev mod thing but I do have an 02 controller thing...

Over to the knowledgeable ones to help me out.....ayethangyew.
