To make sure we are actually talking about the same stuff, refer to this schematic:
Crankcase
Are you talking about #10, 12 parting or #11 parting? And were the bolts pulled in two, or did the nuts fall off (either #18, 22 or #20 depending on above)?
No, the tranny is not bolted to the frame directly. The front of the engine is bolted to the vibration dampener attached to the frame. The back of the engine is bolted to the front of the tranny, and the back of the tranny is supported by the swingarm pivot shaft that is secured in the frame on both sides in elastomer isolators.

Its was item #10, 12 that were sheared. All that was left was the top of the bolt, the shanks and 1/4 inch of thread. The remaining nut and bolt were gone. I replaced both bolts today, inspected as many other bolts I could find and took a 500k ride today. The ride was smooth and there were no loud vibrations while riding bumpy roads. When I got home I also checked for leaks at the front and found none.
I got my fingers crossed.
Another problem has appeared since hitting that pothole.
The bike wont idle below 1000 rpm. I disassembled the S&S carb and found that the float had twisted almost 1/8 ". I tweaked it back, setup the correct level, and gave it a thorough cleaning and put it all together. After adjusting the mixture and idle screws, she purrs like a kitten. :bigsmiley11:
Another problem has popped up since running into that pothole.
I'm getting a speed wobble on high speed turns. At first it wasnt to bad but now its getting serious.
I checked every bolt on the front forks for tightness with a torque wrentch.
I checked for bearing run out with a dial indicator and it was in spec.
I did the same with the tire and rim and saw nothing unusual.
I am not a seasoned mechanic so I had my brother inlaw check it out.
There is nothing like experience in situations like this.
He slowly rotated the tire and found one spot that was tighter than the rest and found another spot that made a slight clunking noise while wiggling the tire back and forth.
I going to Boss Bearing now to get a replacement bearing.
This site has been very helpfull but in some situations there is nothing like true experience to help find a problem.
