Hey guys, I'm a 05' Z400 owner but we are running into the same problem that you guys had with your magnesium valve covers.....

Suzuki decided to use a magnesium side case on the 05-06' motors, and run the water channel through. We are now finding that the coolant is eating the magnesium like it was on the cannondale valve covers. I've been reading ya'll archives and getting the info on what coolant to use, and just wanted to verify a few things....
It seems the only way to completely remedy the problem is to A) go back to an aluminum cover, or

run Evans coolant. But it also appears that if we use deionized(sp?) coolant and change it in at least 6 month intervals that we should be ok as well?
Could some of the C-Dale gurus help us out with some verification? We'd all GREATLY appreciate it.
