The mechanic told me he just uses a lot of grease on the drill bit for the tiny hole that actually goes through to the combustion chamber and on the tap in the bigger part of the hole...Has worked fine for the past 2000 miles... something might go wrong later down the road but at 75000 miles i can blame it on a **** load of different things also... If i start to worry about this hell i might as well sell it...

If you go to the manufacturers page rather than just a vendor page you get lots more information.
Doesn't seem to be that bad of a deal. Looks like they use a longer spark plug so that is not a issues.

With that being said, one plug would be located further into the head compared to the CR plug. Would that affect anything????????????????????????????????

I'll see what the company has to say about the plug length issue.

Site says " simply replace your spark plug with the same type plug that we modify to work with our release banjo "
Kit is one release and one plug for $150, additional spark plug is $25

We know what's included, the problem is you have one plug further in the head then the CR plug. That may be a big issue with the newer bikes and the sensors/ECM. I checked and found no evaluations of the product on the net. I guess easy is not always the best way.
