BMW R1200RT K&N air filter

Thinking of changing the air filter to a K&N type on my 2005 BMW R1200RT, my question is….are they any advantages using a K&N and does any other bike part require adjustment?

Also, any suggestions of how to refurbish the front engine cover which is badly corroded around the central area, black paint is flaking off all helped by the now removed sponge sound proofing behind the plastic cover. Many thanks for any ideas.

I have a K&N in my FZS1000.  There is supposed to be a performance advantage but I'm sure it is minimal without other changes.  The biggest advantage is the extended service life.  Just clean and re-oil rather than replacing it.

As the BMWs run very lean as OE, you would have to make some fuelling adjustments if you fitted a K&N. There is such a thing called an "Accelerator module"

The front engine cover can be stripped and repainted in situ. Once it is done, you might want to fit a crud catcher from Mark Hooton
