what exactly did you do that makes you feel it needs to be replaced? Cracked 'what' exactly?
Well, I kinda sorta tightened the drain plug just a wee bit too much. Apparently the torque wrench I was using wasn't set at the correct torque, and I also have a tendency to over-tighten things regardless of how many times I read "DO NOT OVER-TIGHTEN THE DRAIN PLUG". I ended up with three cracks 'starring' out (if that makes sense) from the plug hole. I realize now, being much more educated on this issue, that the drain plug needs very little torque... ie. a torque wrench likely isn't even needed.
My worry about even trying to attempt a quick fix was, while JB Weld may work for the cracks in general, it may not fix where the cracks and the drain hole threads meet. A local shop figured they could do a decent job fixing it, and would re-tap the threads if necessary... but I didn't want to chance having further problems, especially when it comes to oil possibly dripping on to my rear tire.
So I bucked up and will have the bike in the shop next week for a new pan. $411 Cdn (more or less on par with BikeBandit after exchange, shipping and all). After gasket, labour, oil change, etc, I'll be in to it for around $600. All because I had a brain fart and over torqued a bolt. Expensive lesson to learn, but man do I feel smarter (and at the same time much stupider) for it.
BTW - I will post pics for 'educational purposes' in the next day or so. The only thing better than an oil thread is an "I royally screwed up my oil change" thread, with pictures!
