governor explode

[lillightnin]

Read where raising rpm without removing governor will cause it to grenade. Any truth to this ?

Not generally, but what engine are you asking about?

The motor will throw a rod or blow up the flywheel with the govenor disabled unless you install a billet rod or billet flywheel. safty first!

Three briggs 8hps all running with the plastic/metal gov parts laying in the bottom of it. Metal slings up and gets caught in places metal shouldn’t be and beats the crap out of everything.

I had a 212 that I did a governor bypass on. The engine had maybe 5 minutes of run time on it when I pulled it apart to do the rod and flywheel. I found governor pieces inside the case. Luckily there was no damage done, but it could have been bad.

If you want to remove the governor do it correctly. Fully remove the governor and install a billet rod and a billet flywheel. If you can't afford the parts to correctly mod an engine you shouldn't be doing it.

I don't race, but I make more power and go faster than I need to go, without removing any governors. I don't install carburetors that bypass my governors, either. My engines are reliable, I do not spend hours trying to tune a motorcycle carb, and I do not worry about my flywheels exploding.
If you want to build a race engine, buy another one, put it on the bench and build it the right way. You should not modify part of it, ride a while, then build some more. Someone might get really hurt, or die.

Was this a trick question? Read the OP again-

Clearly states "without removing the governor".
If the governor is not removed, wouldn't the governor keep the engine safe?
I could be wrong

 

[joshua. c.]

The governor keeps the motor at a safe rpm, some governors do have a bit of ajustment avalable but increasing beyond this provided limit blows up the motor.

If the governor, which is centrifugal, is left inside the case, but disconnected from the throttle linkage, (by installing a motorcycle carb) then the engine can spin the governor fast enough to sling the weights off of it into the crankcase.
The governor should be removed when installing a motorcycle carb.
Billet rod and flywheel should be installed at that time, also.

I just wish the OP was a little more clear on the question. Wonder if they will ever come back to this thread?

Did you get your answer?
If not, please try to ask a question with a little more detail.

To answer your first question, it depends on how much the RPM is raised from stock governed. Do you know what the RPM potential of your engine is when tire size and gearing are considered?

Let's say that you don't care to figure all that out. Then to be safe you would remove the internal governor at the same time you are replacing the rod and flywheel. Done.

Some of this stuff shouldn't be short cutted to save time and money.
