Will it fit my Predator 212?

Only the Hemi version, model 60363 or 210FA, identified by its cast aluminum valve cover. It does not fit the non-Hemi 69730/R210 with the stamped steel cover.

Do I have to open the engine case?

No. The kit is designed to install without splitting the crankcase. The cam goes in through the side cover, and the flywheel and springs are external.

What fuel does it need with the bored carb and cam?

Run premium pump gas or better and expect to rejet the .650 carb for your altitude and exhaust. The higher compression and cam overlap make regular fuel a poor choice.

Are 18 lb or 22 lb springs better?

22 lb springs control valve float at higher rpm but add valvetrain wear; 18 lb is gentler and fine for a mostly stock head. The kit ships with whichever is available, so confirm before ordering if the rate matters to you.

The stock muffler chokes the gains from the cam and carb. The optional header is worth adding for a kart or mini bike, and it will need a quiet core if noise matters at your track.

What else should I upgrade with it?

A billet connecting rod is the usual next step once you rev past the stock limit, and a tach helps you stay under the flywheel's rating. Check valve lash after the first few runs.
