Flywheel Magnet epoxy flaking off. What do you think?

[MekaniX]

All of the magnets are intact and don't feel loose to push around by hand,  I've picked the loose epoxy off as much as I could.   I'm wondering if it will fail soon and what yours look like guys.

this is the only replacement I have handy.



This is the original

If it were me, id not epoxy it. not sure of hte pros and cons, but if your luck is anything like mine, it would fail

My options are to leave it as is and run it or replace it.  I'm just curious if this is something that happens to lots of people or is this where you would say  and replace it.

I don't think it fails very often. Here we do not hear of it very often. The magneto is the same even in 2009 models so I think it is fairly reliable.

Unlike Kawasaki EX500's (aka Ninja). 87-93 they had a magneto like ours. 94+ they encased the magnets due to failures. The two suggestions on the EX500 forum is to replace the magneto on older models (they call that Gen-1) with the Gen-2 magneto and the cam chain tensioner.

That we never had a change in the magneto I believe means it was reliable.

This is a known problem with the V-strom crowd as well.
While it isnt all the common, heat, oil and vibration take their toll on any soft parts over time.I just replaced the stator and RR on my buddies DL1000 and checking the magnets for loosness or flaking epoxy was high on the priority list considering the high milage and cost of parts if they fail and take out other stuff.
That said, my project 89' GS with 63,000 miles on the original engine has no such problems.

If its not that common on these I could take this as a sign to change it now before it goes completely. 


This rotor came out of an engine that blew a rod bearing and ran for quite a while like that.

I'll take one of yours Adidas,  It has to be in better shape than this one.
