Well, you all should remember the saga of the broken swingarm at 70mph. He was able to keep it upright and get it off the road. I got it in and the rear diff and swingarm were destroyed. For those that are not aware and those that do not remember, the link to the previous post is below.

Well, I was able to find the time and space to get it in to find the damage. At first, I thought there was a slight chance of the clutch hub nut had backed off and caused all this---not so. Got the engine pulled with alittle help from Josh and then pulled the pan. Found broken teeth immediately, so the pics say the rest.
A few teeth missing here.

And the teeth were found there.
Yes, that was 5th gear idler, 5th gear itself, and the evidence in the pan. What this shows and proves, is that the problem did not start in the tranny. The tranny was shocked from the deadly rear wheel lockup and ate the teeth right off the gears. To be honest, I expected much more damage. There are now only 2 options for the cause, which were mentioned in the other post. The swingarm broke or the secondary bevel gear bolt that backed out. Now the cause of the bolt backing out has been solved. This engine has been apart before---appearantly for tranny issues. That person or tech did not do their job and torque/locktite that bolt down. Well, the true cause of all the damage lies between those two points. We may never know which one, but now know more about his bike than was previously know. All in all, it could have been much worse and we were able to get a crazy deal on a spare engine where most of the parts will be coming from---plus a couple of new parts. Josh is trying to get free for the meet. Hope to see him there!
