changing your oil a job for me or a mechanic?

Or get oil filter pliers. They work much better than a strap wrench. My set of Oil filter pliers only cost $7

Most filters tell how much more to turn them after the gasket has touched the mating surface at the engine. You may be able to get away with not using a torque wrench for a little while, but it will catch up with you. Most bike oil pans are aluminum and repeated over torquing of the plug will pull the drain threads out from the hole. It is repairable, but is is cheaper to get a torque wrench and learn to use it. AND USE IT.

I went out and bought a torgue wrench after I twisted the head off the bolt once. The wrench was alot cheaper.....

I did that after draining the radiator. But the bolt is in tight so I'm not worried about it.
