Planning on doing the same however on talking to others you get a pro - con debate, the normal filters are not as efficent or as good as cleaning the oil as the cartridge we have on now. Mine is on back order because there was a very bad casting problem and the suppliers had to pull them all,(sorry don't know the brand), one user of a spin on mentioned something about a small gasket that is no longer supplied like with our cartridges and you can get leakage, (more than LBC normalities) good things are not having a whole litre of oil go down your arm when changing the cartridge or fiddling with the gasket and not pinching it so you get a major leak. Even though mine is on back order and not here yet I still have not decided, will do some more asking and will view this site to help make up my mind. Thanks for asking this question. /ubbthreads/images/graemlins/thumbsup.gif /ubbthreads/images/graemlins/canpatriot.GIF
