Cometic 3 piece Head gaskets

[Big Dave]

The gaskets came in the top end kit I bought but do not tell me what they are

Anyone have the crush specs for these , they are .067 out of the box

Thanks

Dave

That depends on how you measured them.  The size (thickness) is in the part number for the gasket.  That'll be on the box (or bag they are in) or listed in the kit number. If bought separate the invoice part number may be there.

[Big Dave]

The head gasket part number listed on the box is H0872SP

I cant see how the thickness is in the part number

Cheap digital caliper but reads closer than a tape measure

All Cometic part numbers that I am aware of for HD start with a C
Like the following from the Cometic catalogue and even the kits start with a C
I could be wrong and I usually am but H0872SP is not in the Cometic catalogue.

C9894-040 ...... 3.937" Head Gasket .040" MLS All Twin Cam Models 97" & 107" 1999-17

What makes you believe they are Cometic?

[Big Dave]

Tried to post pics but no luck , Cometic box , cometic labels etc

Kit number 0934-1206 , number under that C9146

Dave

[kd]

Like this ?  You can see the head gasket id identified in the part number.

[Big Dave]

Yes but my kit number has C9146 but no dash anything

Dave

[Big Dave]

Would I be able to E mail the pics to one of you ?

Dave

[kd]

Where did you get the gasket set.  It may be a bootleg set put together.  I found Taiwan sets using that number and Drag etc but the Cometic search never showed it.

[Big Dave]

Everything I get is mail order , this came from Konquers in Kelowna

Nobody within 150 miles to talk to so ill figure it out

Thanks

Dave

[Big Dave]

And you can't Google its a 40 thou gasket?

Guess im not smart like you

Sorry but it was the first one that came up. But I see your issue if there is no dash. Just upload a picture of the kit label perhaps.

[Big Dave]

Believe me im trying to post a pic but the grease under my fingernails is not helping me with this computer

Dave, as said, I don't think you have a true full "Cometic" gasket assembly.  Call your supplier and quiz them of the origin.  If they are a true bike shop they will know why you are asking and need to know the dimensions.  I looked at their web site and think they may be selling a mostly offshore set.  If you can return them, Cometics are available on line and through reputable suppliers.  Maybe give California Phil a call.

[Big Dave]

Thanks , I will call them in the morning , needless to say im a bit confused right now

Dave

[kd]

Understandable.  I don't know anything about what you have but I would be suspect of it's true origin.  Like I said, call Phil too.  His contact info is in the vendor section and he's a top notch credible guy.  He may know what it is you have and be able to offer you genuine gaskets that will satisfy your needs if those aren't a good choice.

Scotty, are you getting that from the Cometic site.  It won't come up for me.    Maybe I'll have to pull out my paper copy.

[PoorUB]

It is from Drag's catalog. I have been reading but otherwise ignoring this thread, and I found the info in a few seconds.

[kd]

Exactly.  That stuff showed up at the beginning with Drag and several others but it can't be found on the Cometic site.  At least not by me.  Maybe a jobber pac sold exclusively to dealers or an aftermarket made up kit?

Thank you I searched the drag site and all I found was this

https://www.dragspecialties.com/search;q=09341206

still cant find what you did

Dave

[kd]

Exactly.  No details saying what is included and where it comes from.  It also says out of stock.  If you enter that part number in a Google search you will see that set is sold by other sellers too. Unfortunately Cometic does not accept that number and that is why I am suspicious of the origin of the set.  It may be a set put together by someone other than Cometic. As said, maybe California Phil can help you know what you have and get you what you need.

[Coyote]

It's a Cometic kit and it'slisted in the catalog. 0.040"

[Big Dave]

Its on me for not being able to find it , I thought the part number in google would have been a simple way .

Thanks Guys
