Yamabond, ThreeBond, etc...

[Skyboy8950]

So, about to start reassembly of engine. Tore down to crankcase. Removed head and cylinders, side covers, etc. Could someone please answer these questions:

1. Should I use a gasket goo (yamabond, threebond, etc...)?
2. Does it go on all gaskets? Head gasket as well?
3. How do I apply? Small amount on both sides of gasket?
4. What kind should I use (yamabond has 4, 5, etc. and threebond has a bunch of numbers too)?

By the way, I bought a Suzuki gasket kit, no aftermarket stuff here.

Sweet!

No goop needed. They go on dry.

Sky, I believe 3M makes Most of the Yamabond/Suzukibond/Hondabond's. In Yamabond, My preference is the #4,(gray), & use it on A, engine cases, ( the thinest of possible skims on both halves, & assembled while still tacky),B on the top / valve covers of bikes using no gasket (xl/xr's), C, the valve covers of transverse 4's using "paper" gaskets (only on the valve cover side of gasket, in an attempt to keep gasket adhered to valve cover & (hopefully re-use), & D, To salvage broken gaskets in need where replacements arent available & bike "just has'ta go, I'm racing tommorow".. All other gaskets, clean & dry...ESPECIALLY head gaskets, Foremost to remember when using liquid sealers, is that some will ooze. inside & out. & that Japanese motorcycle engines frequently use "oil control orifices" to regulate oil pressure which are about the size of carb. main jets, & can easily be plugged by errant/excessive amts. luck G

For the top end, lightly grease (with lithium or white grease for a bicycle) the base gasket and the valve cover gasket

Do not put anything at all on the head gasket, ever

Since you are doing a great clean up, no Yamabond, etc is needed anywhere. I bought a tube about 1990, still haven't used it up yet.

Those "bond" products are made by Threebond. 1194 is the stuff for in between the crankcase halfs, but unless you split the engine you don't need this. No goop for any other gaskets is necessary.

Oh and for Big T, those sealer products have a shelf life (although I don't know what it is). I'd ditch that old stuff in the trash and get some new if you ever have a need.

[Big T]

Yeah, I already got some Gasgachinch (?) to replace it. I'm sure it's still somewhere in my mess.

And contrary to what Big T said a bove, do NOT put anything, ESPECIALLY grease, on a base gasket!!! Ray.

Well, just to clarify, I am replacing the following gaskets.

• Base gasket (between cylinders and crank case)
• Head gasket
• Side cover gaskets
• Cam chain tensioner gasket

I am not replacing my valve cover gaskets cause I got one of those Real Gaskets, so I will be using that.

From what I heard so far, I shouldn't use any of these products anywhere because I have clean surfaces and new gaskets.

Until someone can convince me otherwise, I will stick with that.
