Good gasket sealer?

[nashville_bill]

I installed the PartsNMore half moon cam end plugs a few months ago and have had no leaks. Although I didn't think it was necessary, I sealed them with Yamabond.

My engine is a '79, would that make any difference or do all XS11's use the same plug?

Just because some product is newer on the market doesn’t mean it's better. I don't think any sealer can totally cure bent up Chevy valve covers but I wouldn't expect it would either. You can used Yamabond to build up a nick in a case mating surface and it won't squish out like other sealers will. I've successfully sealed up some cases that were rather abused by armature mechanics with Yamabond.

Air-cooled engines actually have more stress than their water-cooled cousins. I think Sudco makes all of the Yamabond products but I don't know if they're a Japanese or American company and I don’t care either (we’re riding Japanese bikes aren’t we?) I do know Yamabond and Sudco 3bond work and I have many years of turning wrenches on bikes to back it up.

Honda even released their own version of Yamabond #4. It was first called Honda semidrying sealer then later they changed the name to Hondabond.

Use what you like, and so will I but mine with be Yamabond. I’ve used it on everything from my old POS Peugeot to my Moto Guzzi and a few BSAs and Nortons

I think I would rather trust a Chevy mechanic or some type of brand that was well known as a terrible oil leaker and then had been totally cured. A piece of bent up sheet metal is a lot harder to seal than 2 machined surfaces. Also today's bike sized engines in 1 ton cars see a lot more heat and stress than a air cooled bike should. I doen't doubt that the YAMAHA stuff is a super line of products but i really doubt they intended for them to be used in the jerry-rigging money pinching and poor parts availability scenerios we get into these days! That is what Permatex and others like them are all about! Good ole AMERICAN thinking.If I had my bike apart it would get YAMABOND first. If i developed a problem I would move on to BETTER more MODERN sealers developed to handle problem areas such as these. I think Strom and 66 was trying to say how to "get by" on the old stuff. Not the right way but sometimes it can be the best way. Garry

I always sealed them with Yamabond when I was woking on them in Yamaha shops. There is nothing more bitchy than a customer with a new oil leak.

My former boss at Astoria Honda / Yamaha used to make fun of me for applying Yamabond with my fingers. He always said that I had never outgrew finger painting. I've always though that applying it with my fingers gives me more controll even if it make my fingers gray and sticky. It peels off (eventually.)
