Update: After 3 months or so of pounding/driving it like it was stolen on this swingarm modifications. My son tells me last night racing to the house from the rain that something didn't feel right. I pulled it in the man cave for an inspection-- WOW, we're so lucky this made it back to the house without a total catastrophic failure. Once again- It's so hard to calculate the forces apllied to different parts when doing modifications. Two of these cracks were located at the fender mount location-so they definitely contributed to the stress (vibration & weight of mud). This is another example of added horsepower (even a small amount needing considerable re-enforcement). Since this will be the 3rd rebuild of the swingarm on this buggy due to torque issues- I'm going to OVER do it!!!!
