I was never told that the 08+ models have a different oil pump/system. I was given the HF 154 oil filter and assumed it was right. The 2008 + bikes should use the newer HF 563 filter. I don't know if this is common knowledge, but I didn't know so heads up to all the 08+ owners. The 563 filter is a bit different than the 154. The 563 has a different amount of fins, better seal and most important, it has a different oil flow bypass system that's made to work with the 08+ redesigned oil pump/system. If you have been using the 154 on your 08+ bike don't worry it's ok. I would however look into getting some HF563 for the future oil changes. If anyone can explain this better, please do. Thanks and I hope this helps.
