Product Details

The Cometic Gasket C8810 is a Multi-Layer Steel (MLS) cylinder head gasket engineered for Yamaha TX and XS 650 motorcycles from 1974 to 1982. With a 75mm bore diameter and a compressed thickness of .045", this MLS head gasket provides a precise, durable seal between the cylinder head and engine block — critical for maintaining proper compression and preventing coolant or oil intrusion into the combustion chamber. Multi-layer steel construction offers superior recovery and sealing performance compared to traditional composite or copper gaskets, making it a preferred choice for both restoration and performance builds.

Key Features:

  • Multi-Layer Steel (MLS) construction for exceptional sealing and durability
  • 75mm bore diameter
  • .045" compressed thickness
  • OEM cross-reference part number: 306-11181-00-00
  • California Proposition 65 compliant (cancer and reproductive harm warning applies)

Designed as a direct-fit replacement for select 1974–1983 Yamaha TX and XS 650 models, the Cometic C8810 delivers the precise tolerances and long-term reliability expected from a dedicated powersports gasket manufacturer. Follow manufacturer torque specifications and head preparation guidelines during installation to ensure optimal gasket seating and performance.

Quick and easy with great price

All went well!

Quick and simple

So far so good

Order arrived 1 day sooner than expected with correct components. Did get multiple duplicate e-mails confirming order but when I e-mailed customer service to make sure my order was correct and charged appropriately they replied within a few hours. Overall I was pleased with price and service.

Great communication, Great prices! They beat all the competitors hands down on price for my cold air intake order #18986. Quick shipping and they are now in my favorites for places to look for automobile needs. The only thing I would like to see them change is the speed of their website.

First time buyer

Autoplicity gave me prompt notification both when my order was processed and when the order shipped. The price was the best I could find anywhere, and several good reviews made me confident in my choice of stores over other stores who were charging more. Thanks, Autoplicity!

I bought 2 pairs of Stainless Steel polished 12x16 mud flaps. I looked at quite a few mud flaps for my Escalade EXT, and these were the only ones I could find that were not plastic or rubber. They are excellent, heavy duty, polished stainless flaps; and mounting hardware was included. They were well packed, shipped fast and at a very reasonable amount. Best of all they were $26.00 cheaper a pair. So I saved $52.00, got fast delivery, and got a very nice product.....Thank you Autoplicity; definitely saved in my favorites....Bill in Pittsburgh, Pa.

Great prices

Ordered Monday afternoon & it was here Wednesday! Can't get any better than that. Called prior to order & they were very helpful & without a long wait time either. I bookmarked them & will be sure to buy auto parts from them again. Thanks again.

Item arrived in good condition and in a timely manner.

By far the lowest price i've seen on the web for what i have been trying to get, the Injen SRI for my juke. Great price fast shipping! Ill buy all my car stuff here from now on.
