Our take on the Predator 212cc Hemi Racing Kit – 3.308" Rod, 10K Flywheel & 70mm Piston

A rebuild kit for the Predator 212cc Hemi engine used in go karts and mini bikes. It bundles a 3.308-inch connecting rod, a 10K-rated flywheel, a 70mm piston kit, 18lb valve springs, a gasket kit and a magnetic oil drain plug. The parts target higher rpm and more durability than the stock internals, so it suits builders who already run a Hemi 212 and want a stronger short block. It is not a bolt-on power adder for a stock engine, and it does not fit the non-Hemi Predator 212.

Pros
  • Bundles rod, flywheel, piston, springs and gaskets in one kit
  • 10K-rated flywheel raises the safe rev ceiling over stock
  • Billet-style 3.308-inch rod is stronger than the stock rod
  • 70mm piston kit restores bore and compression on a rebuild
  • Magnetic drain plug helps catch break-in metal
Cons
  • Fits only the Hemi-head Predator 212, not the non-Hemi version
  • Requires engine teardown and careful torque and clearance work
  • No carburetor, cam or head work included, so gains are limited alone
  • Flywheel and rod upgrades call for a stiffer valve train and tuning

About the Predator 212cc Hemi Racing Kit – 3.308" Rod, 10K Flywheel & 70mm Piston

This is an engine rebuild kit for the Predator 212cc Hemi engine used in go karts. It fits the Predator 212cc Hemi engine only. The kit includes a connecting rod, a flywheel, a piston kit, valve springs, a gasket kit and a magnetic oil drain sump plug kit.

The flywheel is made of high-strength aluminum for reduced resistance, higher RPM and increased power. Its thread design secures it firmly for stable high-speed rotation and smooth operation. The valve springs are 18 lb and provide extra performance at over 7000 RPM. Length and rate tolerance varies from spring to spring.

When installing the rod bolts, tighten them in three stages rather than all at once to avoid stripping. The rod bolt torque is 170 inch-lbs.

Questions and answers

Will this fit my Predator 212cc?
It is made for the Hemi-head Predator 212cc only. The non-Hemi Predator 212 has a different combustion chamber and piston, so these parts do not match it.
What is included in the kit?
A connecting rod, 10K flywheel, 70mm piston kit, 18lb valve springs, a gasket kit and a magnetic oil drain sump plug kit.
Do I need other parts to run it?
Plan on a cam, carburetor tuning and a valve train that matches the 18lb springs to get the most from the higher rev ceiling. The kit covers the short block, not the top end.
Is the flywheel safe for high rpm?
The flywheel is rated to 10K rpm, which is well above the stock limiter. Keep the coil gap and torque to spec and stay within that rating.
Can I install it myself?
Yes, if you can split the case, check rod and piston clearances and torque fasteners to spec. A shop manual for the Hemi 212 helps.
Where is the Predator 212cc Hemi Racing Kit – 3.308" Rod, 10K Flywheel & 70mm Piston cheapest?
