Thanks for the great write up, @noodles.  I pinned it and added it to the master list of "how to's" so it will be easy for people to find.

How long have you been using this "flush solution"? Do you do anything to neutralize the acidic nature of the vinegar? 

Vinegar works well to remove rust from fuel tanks and such, but it will continue to eat away until neutralized. It can be corrosive to the rubber seals in fuel tanks and petcocks, and will cause further flash rusting. I know coolants are manufactured with additives in them intended to neutralize any acids that may develop inside a cooling system, but I wonder if they are able to cope with the amount of acid being supplied in a flush like this?

Just thinking out loud.

Reuse it.

That's the point of flushing with more distilled water at least once after emptying the vinegar solution. The vinegar is in the system for such a short time I have no worries about corrosion or seals. By flushing with pure water, it will dilute any residual vinegar to such low concentration I have no fear at all about damage to the cooling system.

Was one container of the engine ice enough for the fz07/MT07?   Or is ok to mix with distilled water to bring up to proper levels?

I'm 99% sure one bottle of Engine Ice was enough when I did mine a couple years back-

One bottle is plenty. Just changed mine and even have a little left over 👍

suddenly my four and a half year bike started thermo-siphoning to and from the reservoir a few weeks ago. I must have inadvertently fixed a leak at the radiator cap when I removed it last to check the fluid level.

One container is exactly enough, plus a little extra in case you spill.

I'm with you on this one.  The flush seems largely unnecessary and possibly damaging.
