Price gouging!...
I understand the price gouging........that's one of the reasons we're here.
The fogging spray is what your going to use to coat the internal components with a film to keep moisture from building, then starting the rust and pitting cycle.
I'm not really familar with the air induction system of the M-2 but I think Rookie101 said there was a plug on your air box somewhere for injecting fogging spray. You do this with the engine running. Then, when you shut down, most usually take out the plugs and spray a dab into each cylinder.
That link above, follow it back to that thread. Look for Rookie101's post, then with your mouse, move over his name and click. You'll get a choice to read his profile, other posts or send him a PM. Click on PM and send him a note asking for his assistance. I'm sure he'll help you out. I think the 250 DI is one of his favs..........:cheers:
