Non-riding day in Brissie today, so time to overhaul the K&N air filter.
Did the spray clean and water flush. High humidity, cold day, so helped the drying process along with the hair dryer.
Oiled her up- seems the kit runs out of oil before it runs out of cleaning spray, but I see in the SuperCheap auto catalogue they have the oil selling separately.
All good. Check the instruction sheet to be sure all done. Note underlined phrase "Dry naturally". Hmm. That's probably why I left it in the sun on previous occasions. Still, time to put it back in the airbox.
So now I know why it shouldn't be dried with hot air. The plastic base apparently shrinks enough to prevent the filter fitting over the lugs in the airbox. It's a very neat fit when new. Oops.
Fortunately I have a bar clamp that expands as well as compresses, and a bit of judicious stretching got the filter to fit in place.
There's always something, isn't there?
