Best Predator 212 engine upgrade kits

Start with a Stage 1 kit. It's the best value for a stock Predator 212: air filter, jetting and a freer-flowing exhaust, bolt-on in an afternoon, and it wakes the engine up without touching the internals. Buy the version that matches your head — Hemi and non-Hemi take different parts.

Who the others suit:

• Stage 2 kit — you've done Stage 1 and want more revs; adds valve springs and a bigger carb, so it needs a little more tuning know-how.
• Shredder-head Level I / Level II kits — real power jumps (Level I is quoted around 12+ hp) for karts and minibikes that get raced or ridden hard; Level II is the more serious build.
• Modified Level 3 / Level 4 engines — not kits but complete built engines with billet flywheels and Mikuni carbs, for someone who wants the work done for them.

Check your engine is Hemi or non-Hemi before ordering anything.
