Will this fit my Predator 212?

Only the Hemi version. It does not fit the non-Hemi 212, the Ghost 212, the 224 or Honda GX200 and clone 196cc engines. Check the valve cover shape and engine code before ordering.

Is it worth it over a stock engine?

If you plan to remove the governor and spin the engine higher, yes. The billet flywheel and rod are the safety-critical upgrades, and the cam and piston add real power. On a governed stock engine the gain is small.

Do I need other parts to run it?

Plan on governor removal, a carburetor rejet, a free-flowing intake and exhaust, and often heavier valve springs already included. You also lose the charging coil with the billet flywheel.

Can I keep the electric start and lights?

Electric start can be kept, but the billet flywheel has no charging ring, so lights and battery charging from the engine stop working unless you add a separate charging setup.

A short-fin billet flywheel, a 3.308 billet connecting rod, a .265 camshaft, a flat-top piston with rings and wrist pin, 22 lb valve springs, a high-compression head gasket, a side cover gasket and a spark plug.

Is this for beginners?

No. It requires splitting the crankcase, checking clearances and torquing the rod and flywheel correctly. A mistake can destroy the engine.

What reviewers say

Owners of Hemi 212 builds rate these parts highly for waking up the engine and holding together at high RPM. The recurring complaints are fitment confusion across 212 variants and the work needed to make the kit run right.

What people mention

Power gainPraisedOwners report a clear jump in RPM and pull after the cam, piston and flywheel go in.
DurabilityPraisedThe billet rod and flywheel are trusted to survive the higher RPM the kit unlocks.
FitmentCriticisedBuyers say it only fits the Hemi 212 and that other 212 versions and clones are ruled out.
TuningMixedIt runs poorly until the carburetor is rejetted and the exhaust opened up, which owners say takes trial and error.
InstructionsCriticisedThere is no build guide in the box, so prior engine experience is assumed.
ChargingCriticisedThe billet flywheel drops the charging ring, so lights and charging coils no longer work.
