Do I (or should I) put something on the half moons on the valve cover before reassembly? If so what do you reccomend?

Thanks guys
 
You shouldn't need anything on them, I dont use anything on mine and they have never leaked. If you want use some high temp silicone and they will never leak. We have stuff here in Oz called Ultra Blue and it is terrific.
 
I use sealer on the round portion that fits into the head. I'm pretty sure that's how they came from Suzuki so that's what I've always done.
 
I applied a thin layer of black hi-temp silicone on those areas...just in case.
 
Thanks guys,
I'm gonna seal 'em. Don't want to risk leaking and having to take it all apart again. Sucks, i'm really anxious to get her back together (just rebuilt the carbs, adjusted valves) but the wife has the cage, and I have no way to get to the parts store! I guess I wait one more day...:(
 
I believe the manual on my 450 said to.

I put either RTV silicone black or grey on them, a light layer on both sides. Can't hurt.
 
Yamabond works great.

True but...we don't want any YAMAha labeled products going into our SUZUKI's.:mad:

Best to get the Suzukbond instead, or get Threebond since they are the company that makes all those XXXbond products. Z1 Enterprises sell it.:cool:

Do they make a specific GSbond? :rolleyes:

Being 'Bond' it should be "shaken not stirred" - right? :D

The only problem with putting sealer on both sides of the half moon is that it will now tend to stick to the valve cover gasket, too. If you are reasonably careful with the gasket, you can re-use it a time or two. Using sealer against the gasket minimizes that possibility.


Put 'em in backwards so they can't pop out.
True, they can't pop out, but they might pop in. :eek:

.
 
I put a thin layer of high-temp silicone on the bottom (curved) part.

I'll second whoever said don't put it on the top - it'll stick like crazy to your valve cover gasket and could cause problems when you need to replace that gasket down the road.

Edit: Oh, sorry, Steve. Whoever, indeed.
 
I use Permitex 2B sealant on my GS1k's half moons. I also use the same sealant to coat both sides of gaskets just for extra assurance against leaks. The 2B is non hardening so it's not a pain in the ass to take things apart if need be.
 
Yamabond works great.
i put jamesbond on mine.......haha I am so lame.....

any who yeah I found out the hard way that thos pop out after you take of the valve cover........that sucked I was test driving it and it popped out I was only about 1 mile away form home but man did that hurt all that hot oil all over my leg I had to put my foot up on the cover and get the bottem of my shoe all full of oil and my leg was on fire. good thing I was moving so the wind cooled it down pretty fast. :D Lucky guy here.

So the fact of the matter is put silicon on your valve cover plugs.
