yamabond

It says "Non-Hardening" right on the package... That's another reason I thought it would be okay.

Oh well, I don't know, that's why I ask.

It's kind of semi non hardening,You can use the grey but just hit a bike shop and get a tube of Hondabond 4, Yamabond 4 no longer available

I'm putting together a 029 super clam shell... I want the Hondabond 4 for that?

I've never used the stuff and I don't know anything about it.

I asked the local Stihl dealer, and he said they just use silicone... I know THAT'S a no-no, I asked him to look up the price of a tube of the stuff Stihl recommends (I can't remember the name of it right now), it was like $16! DAMN! I'm only gonna use a couple drops of the stuff!

Been a motorcycle mechanic for 22yrs,over the time mostly at Yamaha dealerships(Here in NZ and AUS),Yamabond is really good stuff,sealing crankcases together(no gaskets,if it fails its a complete re-strip down!!)etc,clean surfaces(petrol on a clean rag)apply to one surface,not to thick or thin and yeah give it a minute and assemble,Ive rebuilt more motors than I can remember using this stuff and trust me Ive never had a leak.The golden rule as with any rebuild is that"Cleanlyness is next to holynest",remember that simple line and you wont go wrong,trust me.
Hope this helps.

I just stopped at the yamaha shop. he only had yamabond 5. is this acceptable for base sealant?

 

[nmurph]

I don't know about 5. I bought a couple tubes of 4 about a year ago. My local shop is no longer a dealer so I whipped into a Yamaha dealership while I was on a trip.

My procdure for use is-

clean both surfaces thoroughly
apply a thin coat to both surfaces- I use a putty knife to get a thin, even coat
install and give a little twist to the cylinder
bolt everything on and run the saw- I have not had a problem running saws within 20 minutes of apply YB4

I know this is kinda off subject, but has anybody ever thought of using Permatex Aviation form-a-gasket? It's some old school sticky brown goo in a white bottle with a brush top lid. I never really thought about it until I found a couple bottles in the shop from a while back. We used to use it in the rock quarry to seal paper gaskets. It says it can be used for close-fitting machined surfaces and is resistant to gasoline, oil, and grease up to 400*. I think it would work on a base gasket and a bottle would last 2 lifetimes. Available at almost any parts store.

Form a gasket is non hardening, like pipe dope, if that makes a difference to you. I use it on gaskets all the time, but would not use it on machined surfaces.

My understanding is you would NOT want to use the NON-Hardening in this application. Permatex makes a hardening and non-hardening material and I believe Yama/Honda-bond does too, make sure you know which one you have. I use the non-hardening on my differential case cover and valve covers. Something like a cylinder base or crank case is where I would use the hardening material.

From Permatex's web site:
Form-A-Gasket® #1: fast drying, hard setting, designed for rigid materials and flanges. Form-A-Gasket® #2: slow drying, non hardening, designed for sealing cut gaskets on non-rigid, vibrating, stamped parts, allows for easy disassembly if required

Where would you use the Aviation Form-A-Gasket® No.3 Sealant? The Aviation Form-A-Gasket is a slow drying, non-hardening, sealant, resists gasoline, oil and grease. It is used for close-fitting machined surfaces, sealing hoses and solid gaskets.

One thing to be careful of is how much you use. Never use too much of it as it can/will squish out when mated together. Its more important in 4 stroke engines because if you use too much and it drips on the inside of your engine it could come lose and block and oil port.

Apparently yamabond 5 is a drying formula. So this would be correct?

Yamabond 4 is the stuff you wanna use. It is semi-drying.

 

[Marshy]

From what little info is available in that link, I would use Yamabond 4 as it said it is sutible for high temperature. It said it is "drying" I consider that hardening... Or save a few dollars and get Permatex brand. Just my $0.02
