I've got the Blaster completely torn down now. While cleaning the grime off of swing arm I found it's been cracked. What's your opinion - should I definitely replace or should it be ok?

Um deff. replace that babby. lol thats bad. You might beable to have an experienced welder fix that but i dont know about that either.

 

That's what I kinda figured. I'm really wondering how the hell it go cracked like that. The cross member on the frame directly above that was bent up about 3 inches - I'm guessing some lard butt bottomed it out on a jump and darn near got the rear shock and brake rotor embedded in their butt and cracked it in the process. LOL

EDIT - cracked the swing arm - not their butt... LOL - sounded funny after I read it.
