500 Twinair air filter, spark plugs & coil replacement

Turn the engine cover upside down and remove the 6 bolts/screws with a 7mm socket. These won't come out completely, keep unscrewing them until they are loose and are free to move up and down.



Lift the air filter cover out and turn it upside down. Lift out the old air filter and admire the filth - apparently mine was changed 10000 miles ago. Ohhh I love garages that play these kind of practical jokes on me.





Brush any dust/dirt out of the filter box and pop in the new filter. Place it back on the engine cover and tighten up the 6 bolts.
