ABOUT THE DYNOMAN F2 PISTON KITS:
As the 77-78 Honda 750 F2 has a 18% larger combustion chamber to compensate for the larger valves, through the years many people have installed the standard 836cc (ex: Wiseco K836) kits for the 69-76 engines only to discover that the compression was too low to give them the extra power that they were after.

Dynoman offers our custom 836, 915, and 970cc piston kits for the F2. They have the correct dome to raise the compression to a true 10.5:1 and 11.5:1 respectively.

These pistons are state of the art diamond cut on CNC machines in the USA from 2618 aluminum forgings. This is the same alloy used in many pro stock pistons. This process makes them lighter than some of the cast pistons used in the 70s, but much stronger. They also come with a brushed dome to smooth any sharp edges.

The pistons feature large valve pockets for the 31 and 34mm valves used in the F2 engines. They also have contact reduction grooves above the top ring for pre-ignition control, and accumulator grooves below the top ring for better ring control.

The DP836/65f2 kit is the same bore size as the standard Wiseco K836cc kit, so they are a drop in for any F2 with the standard K836 Wiseco kit already installed.

Custom Piston Options at Dynoman

Available DP Custom Piston Options:

ACCUMULATOR GROOVES An accumulator groove is machined into the land between the top and second ring. It provides additional volume where residual combustion gases that have "blown by" the top ring can collect. This additional volume helps to reduce pressure between the top & second ring, thus aiding in top ring seal and minimizing ring flutter.
LATERAL GAS PORTING This process mills slots into the top of the top ring groove and provides a pathway for combustion pressure to get behind the top ring. This process helps to increase ring seal.
SMOOTH FINISHED DOMES Decreases hot spots
CONTACT REDUCTION GROOVES The purpose of machining these grooves is to reduce the amount of contact area against the cylinder wall when the piston “rocks over”. Contact reduction also serves to disrupt the flame travel into the crevice area thus helping to reduce detonation.
3D UNDER CROWN MILLING The 3D Under Crown machining process allows for uniform deck thickness, therefore creating a lighter and more durable piston. photo


 
"ECONOMY' UNDER CROWN MILLING Similar to above without quite as much weight reduction. An excellent balance of cost vs. result.
FULL LIGHTENING PACKAGE For maximum weight reduction

TUFF SKIRT COATING JE Pistons’ trademark coating that is a lubricating, anti-friction / anti-wear coating applied to the piston skirt only. Unlike our standard Skirt Coating, Tuff Skirt will not wear and is designed to withstand many different types of endurance applications, similar to those commonly found in NASCAR. Buildup is .0005” per surface and finished diameter of skirt should include the coating buildup.
THERMAL CROWN BARRIER The thermal barrier crown coating is applied to the top of the piston and is designed to reflect heat into the combustion chamber, thereby increasing exhaust gas velocity and greatly improving scavenging potential. The .0015” thick coating can also assist in extending piston life by decreasing the rate of thermal transfer.
TULIP VALVE POCKETS Most commonly used on Hemi and motorcycle
engines, this process leaves a raised area on plunged valve pockets to achieve maximum compression.

*Some features add production time to build.

How to make a DOME MOLD

ABOUT CYLINDER BOTTOM TAPER
It is common for the tapered lip that came in the bottom of your cylinders from the factory to be removed when installing larger bore piston kits. If the machine shop doing your boring does not taper the bottom of the sleeves after they are bored there will be a sharp edge at the bottom in place of the factory taper. It will need to be removed to make ring installation easier. You can taper the sleeves by hand with a Dremel tool or porting tool using a small 400 grit or finer sanding drum. It is also very important to wash the bores with hot soapy water to remove any sanding residue and oil them lightly when the tapering job is complete. We recommend lightweight machine oil or engine oil. Following this procedure will greatly reduced the risk of broken rings during installation!
