I have seen two of the pipes come off and cause quote a bit of damage under the cowl from the heat. I now put a seperate screw through the two pipes so they can never slide off from vibration. 

Thanks for the tip! Adding a screw sounds prudent.  I was a bit skeptical that the safety wire would hold should the clamp loosen. 

As an aside, I was right to question myself instead of the Rotax engineers.  The stinger clamp bolt was actually the right size - it just looks to small.  By the time the spring clamp is tight enough, there is the proper amount of thread.  I will say though that is quite the challenge to get this clamp on 😂
