At first I thought maybe the primary was leaking. Then I thought maybe the matted black paint was just fading on most of the inner, since I saw no sign of it coming out of the seam between it and the outer chrome. But on closer inspection, my front end is oily and it appears that it's being blown back on to the top of the inner. I'm pulling the manual, but what is the rubber boot that's plugged in, located just in front of the top of the oil filter? It looks like it's not quite flush and where the leak is coming from......easy fix? Thanx

 

that's your voltage regulator and it probably is seeping some oil. The fix is to clean up the area, plug it back it as securely as possible and use RTV to seal it up. Ride on brother!

 

Hey there CB......tried to push it in as best as I could, still won't set flush....what's good to use to clean the oil stain?

 

No worries... mine started seeping oil from there yesterday on my 700+ mile ride. Just clean it, seal it up with RTV as stated, and live with it. I have heard of people using red loctite for this but I'm not sure how well it would work...

EDIT: Your stator plug isn't going to sit "flush". You have a female plug coming out of the inner primary, this is your stator, the outer plug that you're pressing on is coming from your voltage regulator and connects to your stator. You'll need to pop the plug off to seal up the stator plug coming out of the crank case. Periodically check that plug to make sure it stays tight.

 

That's good info, thanks. I'll dink with it tommorrow....too darn nice out to sacrifice riding time.

 

I've had this problem with every Evo stator I've had. They all start to leak oil around the rubber plug. I've tried everything, even removing and reinstalling after coating the plug with RTV.

The proper material to use for this job is "flowable RTV", made by Permatex and sold at auto parts stores. This stuff is made for sealing windshield leaks and is designed to "wick" into cracks and gaps. Clean all the oil around the plug with contact cleaner and dry everything off. Then apply a thin bead of the flowable RTV around the stator plug where it exits the case. In a few minutes, the RTV will wick into the space between the plug and the case and disappear. Wait overnight for it to cure, ride and enjoy.

This worked for me, and my stator plug has been dry for over a year now.

 

Thanx UG
