First, do you have an oil cooler on the bike? If you do then you need the 'hinged' oil filter. If not the standard filter will work. Second is the steel washer/shim that the o-ring sits on, after removing the filter and installing the new one, the steel washer/shim goes on first, then the o-ring ( I put the o-ring on the filter cover and then install it). You'll hear this referred to as the $2000 o-ring. If this isn't installed correctly, it could mean an engine overhaul. I'm sure others will add other comments to this as well.
