Gasket sealers

[JohnK]

Pulled the right cover off the VFR to do Some clutch work and cover surgery - of which is now a step up in my mechanical efforts. If one were to put it back together what sealer would you recommend for the gasket. I would imagine a good high temp version of some kind. I have it all back together less the new cover. Want to avoid oil seepage

A lot of mechanics are using an item called "the right stuff"
A type of form-a-gasket.

I have used the Permatex ultra black oil resistant gasket maker.

The service manual recommends that you install the new gasket, and then apply a small amount of sealant to the ignition pulse grommet only.

I usually do not use any sealant on gaskets unless it is called out to be used. Most gaskets especially those made in Japan do not need any gasket sealer. Most times I will just coat the gasket with a light moly grease when I install it. This helps to hold the gasket in place and allows the case to be removed easily if taken apart later. If you find yourself doing an on the road repair, the old gasket will remain usable if coated with grease.

How did the old gasket look,come off without a lot of effort?prolly had no sealant on it.Lots of residue,had scrape like hell?Sealant.

What percentage of moly in the grease?

What percentage of moly in the grease?

77?

In the old days, you greased paper gaskets, but the VFR clutch gasket is a newer type. Although you don't have to, grease is still a good idea, and a smear of RTV where the ignition pickup is. If not using an OEM gasket, the Athena brand is good.

What percentage of moly in the grease?

Nothing really special - I have a tub of high temp moly grease that I've had for probably 20 years that I use for gaskets.

Thanks will look into that

Not to argue - mine recommended sealant - just saying. Definitely said same about the ignition pulse grommet.

Good advise

It came off relatively clean some remained and had to be razor bladed off. Looks like a factory seal green in color. Was broken at the grommet location. It took a bit of prying to break it loose. Most of it stuck to the cover

The bike is a 2003 6th gen - had a oem gasket of which I ordered a new oem from ronayers - thinking the grease idea is a good idea especially if I make it a track bike. Being able to do remote work and not worrying about a gasket.

Interesting, the 6th gen manual differs to the 5th gen manual there. The 6G manual does indeed say to use sealant 5-15mm either side of the joint of the two crankcase halves, plus the grommet. They are always learning...

Ended up using high temp moly. Buttoned up nicely and no leaks. Thanks all
