Good morning,

I have decided to remove the governor on my predator 212. This will be the first time I have ever removed a governor. I have a good idea on everything that needs to be removed; however, I do not know what upgrades I need to make to protect the engine. Searching online, many people say many different things. The one thing I do know for sure, is that I will need a billet flywheel. Some say to replace valve springs and some people don't, as well as push rods, ect..

I am looking to do the bare minimum of upgrades engine parts, but still be confident everything will hold under higher RPM, and work properly.

Please give me your recommendations! Thanks in advance.

The one thing you "know" is the one thing you don't. You don't need anything if you keep the stock springs.

People are spinning the stock flywheels over six grand. If you upgrade valve springs, then you should get a billet connecting rod.

Just yank that ****er out and Zoom Zoom.

Stock 10.8 lb springs should prevent you spinning the engine faster than the stock connecting rod can handle. 5400 rpm give or take.

At 5400, the stock connecting rod and flywheel "should" be fine.

If you upgrade springs (18-22 lb), the stock camshaft might get you to 6000+ RPM.

However!!!!!!!

Above 5400 RPM (which becomes a likely possibility with upgraded springs) REQUIRES a billet connecting rod!!!!!

The Connecting rod will fail before the flywheel.

The stock flywheel - I cannot say for sure. I spin mine above 6k everyday. I don't keep it at 6k for 30 minutes straight, but maybe I could????

I maybe spend 30 sec to 1 minute at a time above 6k.
I had it up to 6600 RPM.

Some people say I need a billet flywheel. Some say I don't.
Perhaps the new clone flywheels are cast better than older ones??,

When was the last time someone saw a clone flywheel explode???

If I were to build a 7500 - 8500 RPM engine, then I'd add the Billet Flywheel, CR-Mo Pushrods, SS valves, billet rocker arms, billet lifters, automotive style retainers/keepers.





So I repeat, just tank that ****er out!

With all the connecting rods we sell here, ARC should give us a DIYGK discount.

Thanks for the link. However, this link does say to replace the valve springs, so I just want to be very sure I don't not need to replace the springs?

Don't replace the valve springs unless you get a billet connecting rod like the ones from ARC.

Typically if you replace valve springs, you want a billet rod, at least that is what you will hear time and time again on here. However, I have had luck using 18lb valve springs with the stock rod. Be aware, there is a chance for failure with that many RPMS. It is a personal choice to take the risk or not.

But no, you do not need to replace valve springs on a governor removal. Valve float from the factory springs will prevent rod failure.

No billet flywheel required, recommend billet rod but that's just a recommendation (not required), just saw my first flywheel failure this past weekend (stock flywheel) on a kart doing 7500 rpm's and it was no big deal. coil plate came off and wedged into coil stopping the engine. Flywheel cracked, flywheel key sheared nothing flew apart.
