I had my new TMX-360 assembled at Mattituck in February of this year. The Mattituck instructions basically say that the preservation lasts six months, and then you should do a few things to represerve it for another six months if you haven't run it yet. Since I am probably going to be another couple months, I called Mahlon at Mattituck, and he told me not to worry about it.
When the engine was shipped here after assembly, I noted that it didn't have dessicant plugs installed, and called Mahlon to inquire. His response was that since I went with the Titan CermiNil cyllinders, which can't rust, there was no need to keep the cylinders dessicated....made sense to me. But I still almost bought a set of the plugs cause I think they look cool when people see the engine in the shop...
