Now the salt has gone, (fingers crossed) I've been fettling my old girl to get her ready for the road. I needed to change the oil tank that has been seeping oil since I restored the bike. While I had the air filter removed I cleaned the K&N element that I adapted for the machine. I photographed the filter in case anyone is interested in the same mod. The filter is made for the BSA/Trumph triples. It needs to be cut to size. The filter is reusable after cleaning with K&Ns special fluid so should last forever.
