I've said it before, and I'll mention it again. Motorcycle tires undergo some pretty dynamic forces. The front has to bear it's share of the weight, and deal with crazy cornering forces, as well as the majority of the braking force. The rear has to bear it's share, which can be even larger due to passenger etc, the same crazy cornering forces, it's share of the braking (whether engine or brake) and 100% of acceleration forces. I wouldn't trust an external type plug unless it was an emergency means to get me to a more permanent repair. If the tire had enough life in the tread and compound to continue to use, I would use an internal plug patch and go very easy on it. If it didn't seem worth the cost of removal and replacement due to tread life/compound life, I would get a new tire at that time.
It's just not worth it to me, to take that type of chance with my machine, my self, or others around me.
At the same time: I've never known anyone personally have one pull through (although we all hear stories about the friend who has a cousin who met a guy that got soda from someone who read about someone who heard someone else say that they saw someone lose a plug).
Being on a motorcycle is about acceptable risk. If you believe that the plug is accpetable, do it. If not, don't. I choose to not take the extra risks.
