Honda CB750 Ported Heads (K Models)

We just finished 4 Honda cb750 K model heads for the refurbished section of our website.
The heads are ported and will need to be finished when final decisions are made with the cam, spring pressures, drag racing, road racing and such.
These heads are generally used on hot, hot street life and racing up to 1000cc displacements. Above 1000cc displacements and the highest level racing can require more elaborate porting.
Let us know your performance goals and these heads can be generally finished in 2 to 3 days.

Machining Excellence!
 
 

970cc Machined Cylinder and Coated Piston Kit (In stock)

This cylinder has been re-sleeved, surfaced, bored and honed for these Wiseco 70mm pistons. This early cylinder is the preferred year because they do not have the 8 oil drain holes.

Also, our cylinders are machined to accept "O" rings at the bottom of the sleeves. These piston kits were designed for a customer and we have 2 extra sets for sale.

Depending on your combustion chamber, this kit averages in the higher 10 to 1 ratios with "K" heads. This ratio would be perfect for larger camshafts that need higher compressions.

The pistons are made by Wiseco and have a bare weight of 165 grams.

They have an Armor-Glide coating on the skirts and a heat repellant coating which drastically reduces piston temperatures.

By the way, the kits are complete with wrist pins, circlips and rings. The kit also has the best cylinder sleeves in the industry.

These are the same coatings used on all of our performance race bikes and motors. The rings have a chrome top ring for unleaded fuels and 3 piece oil rings.

This cylinder and piston kit is cleaned and ready to bolt-on.

Strong in Performance!

 

Honda CB750 (890cc 67mm) Refurbished Cylinder and Piston Kit (In stock)

This cylinder has been just completed with our 890cc (67mm) sleeves and armor-glide coated pistons.
The re-sleeving procedure consists of removing the old sleeves, boring and honing the alloy block to size. Pressing in the new 890 sleeves and surfacing. Boring and honing the sleeves for piston fitment.
Note: Our sleeves allow the use of "O" rings at the bottom to prevent oil weepage.

The Cycle X designed Wiseco manufactured pistons are our favorite kit.


Note:
People talk about oil weeping upwards and and out the fin area when installing bigger sleeves. Well, we have seen many cylinders that have had this problem and after looking closer at the machine work We can see why. Most of these weeping cylinders have the alloy block bored (not honed afterwards)  which leaves a boring bar machine finish allowing the oil to have a easer path upwards and eventually can loosen the interference fit.
Our cylinder alloy blocks are bored then honed to exact clearances with a fine finish before installing the sleeves.


Includes:
Reworked cylinder.
Coated 890cc  pistons. (Complete kit) rings wrist pins and such.

 

These 67mm piston sets are designed for Honda CB750 (69-78 SOHC) that are using big duration and lift camshafts.
Generally used when camshaft manufactures request 12.5 or higher compression ratios.

Note: The reason we mentioned "early" cylinder is because early cylinders do not have the 8 drain dowel pins and "O" rings. These cylinders work better at times with MLS head gaskets with the added area for head gasket seal.
