Never trust a Haynes manual

Seriously it is an easy job to change the air filter,... While you there check the coolant level in the radiator, cap on the right hand side front of bike under the fuel tank.
Jobs-a-Gooden.  :thumbup

There's a fuel filter under there too... just follow the fuel pipe down to it's bracket. Last time I was delving around, I changed that. Old one had done 20k odd miles. No idea if it needed a new one!
