Featured Product #1:

Big Bore Cylinder Head (Version #6)

We decided to reproduce our hot-street, race head for you go fast folks. These cylinder heads have modified, machined large intake spigots. Honda CB750 heads only allow the intake ports to be opened up to a certain amount before breaking through to threads or atmosphere. Epoxies are then needed. These heads will be offered in "K" and "F" versions and are specifically designed to use our Mikuni RS 34mm carburetors, large camshafts and big bore kits.

Stay tuned for big power.

Featured Product #2:

Full Floating, Self Compensating Cam Chain Tensioner

These cam chain tensioners are designed to float and compensate for milled heads, thinner gaskets, worn/stretched cam chains and hard deceleration which destroys OEM tensioners. The arrows show how the sliders can move a few degrees to compensate for the above mentioned problems.


Proven XPA 46 slider material.
Floating/compensating design.
No more than four chain links unsupported.
Front slider is longer with a gentle curve.
Oil drippers on both rear sliders.
Guaranteed for life!
Stock length cam chains, peanut or straight
    side plates are fine.

Note: Fixed slider designs shift the pressure points upward and only make contact at the very top when thinner gaskets, milling and stretched chains.
