I'll add a short story about a trip my wife and I took several years ago. She was on a Honda PC800. In the morning at the motel, there were about a dozen Harley's and our bikes. The only bike with an oil puddle underneath was the PC800. The oil filter was leaking at the base. How embarrassing
Well, obviously we didn't pack an oil filter wrench, but I was wearing a leather belt. I remembered an old, old trick I was told about. If you wrap the belt around the filter and run it through the loop and pull, you can put considerable torque on the filter. If you try it, you will figure it out. Just be sure to have things lined up to that you are pulling the filter in a twisting motion. Hope that makes sense. It also works to remove a filter in a pinch. If your filter is wiped dry, you belt will stay clean. Sometimes you need the filter just a TAD tighter than hand tight.
