Anyone used RTV silicone gasket with any success ??

[DaveH]

Have got the dreaded milky tranny oil problem and am getting fed up of buying new gaskets each time I remove the RH casing to try and ascertain the cause. I did notice slight oil weep from the gasket mating surfaces of both clutch gaskets when the bike had been standing after a run prior to cleaning (small dark patches in the dust at a couple of points around the edges of each)

Has anyone used Loctite 5920 (high temp copper) silicone sealant on the cases instead of conventional gaskets with any success. The gaskets I have been using (from main dealer but not branded) seem a bit useless to me.

As there are no tiny oil circulating passages a la 4 stroke, I cant really see a problem....just wondered if anyone had tried it and idf so does it work....certainly save a few quid...

It is best not to use any type of silicone sealer on a paper gasket.
If you have to use a sealer, use something like Yamabond.

Water pump seal?

Depending on the model year of your bike you may have a composite water pump impeller. I would suggest replacing it with a billet aluminum one sold by gofasters.

I agree with the Yamabond. I've used this on car repairs, mini- bikes, you name it. On engine cases you can remove the excess with carb cleaner, and I have never had a leak when using it. It's worth a try.

Hylomar is a good dressing for a paper gasket. If your going to go Yamabond without the gasket, it might be a good idea to check if there will be any clearance problems from the loss of the gasket thickness first. Dry fit the cover and make sure nothing binds.

Thanks Glen....didn't consider the clearance issue . Have gone with the Hylomar...we'll see what happens...
