To provide extra cooling for future mods, I got a real nice oil cooler off ebay, perfect size,has mounting tabs to make it a snap to mount up, and threaded outlets to put lines on, just one question ! Where exactly do you cut/ attach lines on the motor for best oil flow? I don't want to start hacking at oil lines without being sure of the best way to attach it. I know on some installs, you need to drill and tap a fitting on the side of the cover, is this necessary on the 300ex? any info would be greatly appreciated.
