Question about 1979 Ducati 900 GTS
I looked at the filter that came off and the part that you screw the filter on was not the same size. The K&N filter was much smaller. The filter that came off the bike was a Scotts cartridge filter one of those that you are suppose to just clean and not replace. Did someone spend a lot of money on this and change out some parts so now regular filters won't work? I'm kind of at a loss here I would like to just start using K&N as the other scotts cartridge o-ring was leaking. Anyone have experience with or seen this? What do I need to do? Thanks in advance for any help.The Scotts filter is a metal screen/mesh and IMO, will not filter as well as one with a paper media like the OEM or afaik a K&N. It's extremely unlikely that the Scotts filter required some type of insert that changed the thread pitch/size on the engine, and much more likely you have the wrong K&N. You want to make sure there isn't an o-ring from a previous oem filter stuck to the engine casing, with the Scotts filter beinbg screwing on over it. It is very possible for those o-rings to stick to the engne, ie pull out of the filter, even if they've been lubed before being spun-on. Good luck,,,
