    Softer,,, really??? Unless KTM uses some sort of different bearing material than everyone else, bearings are three layers. The steel shell, a soft aluminum base and a softer aluminum plating. Once the plated bearing surface gets damaged it doesn't take much more to wear down the base aluminum. That soft chip of tin from the end plate of the filter will do one of three things: pass through the oil gallery and embed into the bearing and not be an issue for the most part. Pass through the oil gallery and be spun around the bearing, scoring the surface with every revolution. Or make it some other point in the engine; maybe a good spot or maybe not.

    I wouldn't take the chance. I have dealt with bearing issues in bike engines and marine engines for going on 40 years.

    Correct. But with the new cover milled to the original profile, the original seal can be used, eliminating that problem.

    Guys, thanks for your advice. In the end, I did neither - went with the bored out cam chain bolt option (as per cpmodem).

    All your (very valid) cautions about debris made it seem like too much of a hassle to have to drill out every new oil filter.

    What I'll do with this oil cover now though I don't know. Oh well.

    Thanks for all your help

    Put the cover in the flea market. It looks like someone might be able to make an oil cooler feed from that for a rfs. Or another ktm.

    Contact Scotts Performance (818) 248-6747 . Speak to them, they make custom oil filters all the time. They could make a filter open at both ends.

    Hell, they could thread the protrusion on your rally cover to thread directly into the filter they make for you. :D

    If you are looking to move it on I'll take it off your hands. PM me. if not can you supply the P/N?
    That part is very similar to the part on the 690rfr that I have and guess what - I punch the filter centres out and use an O ring to seal it. The stock KTM690rfr filters have a blank end - hole punch leaves no swarf to contaminate the motor. Its good to go. Please say you'll sell it......:deal
