Oem Yamaha 760 head gasket thickness?

[SUPERJET-113]

I dont make these 760 SS head gaskets as they are difficult to make with very extensive/expensive tooling dies. I only make ALL the 2 stroke "synthetic fiber" gaskets for all engine models of Kaw, Yam, and Sea-poo, and after market pipes, intakes. Also the rubber Yamaha e-box gasket. Also have all the Sea-poo model O-rings too.

I get these from Gasket technology which was just bought out by Cometic last year. Gasket technology started making gaskets for the Kaw JS400/440 in the 70's here in Havasu. They only sell commercially.
**Also, these newer ones I get now are 2 layer SS embossed, .025" total thickness, BUT, I can also get the 3 layer .025" also.
Here is a pic of the 2 layer:

Did you check squish after install?

Still too big! Lol I think it was .047?? Can’t find the notes

I just saw this. Dont know how old it is. Stock is 3 layers. I took one apart one time. I didnt measure but I think .010 on each layer. They appear to be just like the stock kawi 650 750 x3

Thanks for this info! I'm going to be putting the 760 head gasket on my 701 with a stock milled head and added dual cooling. It looks like aftermarket ones are cheaper, but I'm going with OEM here to get the correct .025" thickness.

701 82mm bore metal head gasket.

Yeah I think this is why people run their secret gaskets for their lites boats. I dont have one anymore, but if I was building another, I would bite the bullet and be using whatever tomski or watcon provides. I couldn't get mine optimal with a stock one.

I took a lites boat apart once and it only had one layer of the oem gasket. Lol - Cheater boat
