any help thanks
PO was wrong with the direction of the filter, so check that there isn't a square o-ring down in the back of your canister (they sometimes hang on the tube).
But if your canister lip depth is only 2.8mm, the PO was right to use at least one paper gasket and at one shim (if the canister edge is sharp, not rolled). If your canister edge is rolled, you can do with one paper gasket, no shim.
It's all detailed on Anton's canister page:
With the wrong direction of the filter, my GUESS is that unfiltered oil could have possibly circulated with filtered oil. OR, the square o-ring could have blocked the oil's route through the cooler, if equipped. But these are total guesses on my part!

I love every motorcycle I've owned and even some that I haven't.
