In trying to hunt down a misfire in my 2008 Rev 4T, I pulled the stator and trigger coil out. Gee look what I found. The PO must have rode it hard and put it away wet!

Looks like its out of a 30 year old bike that has been sitting outside on the Scottish Coast all its life.

Mine was a bit worse than yours

Try the earths at the top of the coil and make sure all your connections are clean and spotless when you put them together

Common cause of corrosion in stators is use of silicone sealant on the cover joint. Many types of sealant give off acetic acid fumes as they cure / harden. This creates a highly corrosive acidic vapour inside the cover.

Use something like Hylosil that contains corrosion inhibitors instead of acid.

Can't see anything wrong...... If the electricity is still flowing then just live with it.

I must be old school... There are some gaskets I use grease on ,never sealant ...

(but if your going to use a rubber type sealer , I believe Toyota 's Black FIPG (form in place gasket) is unmatched in most situations ...)

Yea, obviously you are old and out of date. You need that crap wich corrosion inhibitors.

It looks to me like that RTV did a good job of sealing the water IN. One can still see clean water droplets in the pic! Know what that means, don't you!
