Cycle X High Performance Gaskets

Honda CB750 Super Gasket Set (Race Proven)
"New Version"
Now featuring a oil pump stopper spring, pressure relief spring, oil stopper rubber and oil filter "O" rings. (At no additional cost!)

Cycle X super gasket sets are a premium quality cure for age old problems concerning chrome covers, untrue surfaces, re-torquing
and the need to run to the hardware store for miscellaneous "O" rings.
Cycle X was the first to put effort, expense and test these modern gaskets on Honda cb750s.

Head Gaskets: MLS head gaskets have been around for years. They feature great rebound and are layered steel with a Viton coating.
Base Gaskets: Steel with Viton coating.
Side Cover Gaskets: Alloy with Foamet coating is the same combination used to stop old Harleys from leaking.
Oil seals and every "O" ring in the motor that most kits do not include.

Super Gasket Set "Budget Version"

There are many different brands and prices for conventional gasket sets.

Many of these kits are missing items and a few of the gaskets included in these kits should be upgraded.

We have made a "super budget" gasket set, because we do not have a problem with many of the side cover gaskets and "O" rings. On the other hand, we do have a problem with head gaskets and valve cover gaskets offered in conventional gasket kits. We have done extensive testing on all the Honda CB750 SOHC conventional head gaskets to diagnose why Honda CB750's have head gasket seepage. The testing concluded that conventional head gaskets need to be re-torqued.

To re-torque a Honda CB750 head gasket is a major job, and in many cases the motor needs to be removed. Included in our "super budget" gasket set is a modern MLS head gasket and amf valve cover gasket to avoid the heartbreak of a seeping head gasket. We have also added oil seals and miscellaneous "O" rings to complete the kit.

Note: For 77-78 K and F models you will need a different counter shaft seal. (Call to order, let us know.)

What is MLS?

The outer layers are an embossed viton coated stainless steel providing a superior seal with excellent rebound characteristics and are corrosive resistant.
MLS head gaskets reduce bore distortion and withstand extreme cylinder pressures.
