Years ago probably 1992 I was at a motorcycle rally in a vendor's trailer and swear I saw a kit for changing motorcycles with a flow thru cartridge and oil filter cover to using a spin on type filter that was readily available, I believe the kit had a plate or adapter that fit on the motorcycle engine block and the other side of it was perfect for a spin on filter attachment, has anyone else heard or seen this, who was the manufacturer and how would I get in contact?
