Silicone grease on the front plug cap. - SV650.org

20-02-08, 12:13 AM

I greased up the front plug cap last week and I noticed that there are 5 or 6 small holes in the cap which I presume are to normalise the air pressure under the cap. Wouldn't water get in that way anyway? So is the greasing of the cap doing anything to solve the SV front plug problem?

I'm looking at these two fenda extendas I have lying spare in my garage and contemplating having another go at fitting them to the bike before I take it abroad again.

Fairly pointless normalising air pressure since there's a drain hole that leads down the RHS of the front cylinder

I live in a desert, so cannot act the expert at this, but di-electric silicone grease dabbed on thick enough will keep water out, and tends to stay in place.

On the other hand, if I lived in Jolly Olde, I would have a Fenda Extender fitted, no matter how it looked. And use the grease as well. Can't be too cautious.

Yup. Going to solve it 100%, guaranteed, no extenda required! As for the holes...

The only time there should be any need for vents other than that is if the plug allows blow-by, and a wee bit of silicon grease isn't going to be a problem in those circumstances. I can see the argument against doing it this way, mind, but I've had no ill effects these last 20000 miles

Prostrate yourself before the cap greasing master.

Thanks lol! I am well and truly prostrate.

As it happens, when I took the front plug out it was subject to quite a bit of corrosion.

Now the rear cylinder problem, that's a whole nother kettle of fish

It was the coil, surprise surprise. And Mickey Oates didn't have one in stock so it's still there. Full rant to follow in Ecosse...
