About to do a longish ride, ordered new EFI oil filter for Norge. Arrived, all well except new ones are 14 fluted ones. So out to shed,found 75mm stormwater pipe,heated up on the BBQ a bit and Moulded it to the new filter and old 8 flute removal tool. Looks like it will work to get filter snugged up ok. Maybe new EFI filters are now 14 flutes?
