That flywheel business is pretty crazy! I have yet to see one break under any circumstance.

I got tired of arguing about it.
I fear flying more...or getting struck by lightening...
Much better chance of winning Power Ball than witnessing a flywheel explosion.
Someone is making mucho dinero on this billet flywheel crap...all based on an unfounded fear.

Haha interesting that there is no evidence. I agree with most people, the ones that go are the ones that are abused, and revving at 7,000+ rpm.

It makes me wonder if they are beating the flywheel with a hammer, causing cracks. There's no good reason why a piece of cast metal should fly apart at high RPM.

Should be able to withstand more than that...say 10,000 rpm.

I'll second that sentiment.

I know in the 1960s go kart racers would modify their Victas and get anywhere up to about 16'000 rpm out of them.

Thats with a custom made head, porting, case stuffing, big carb and a megaphone exhaust. Standard rod and cast Aluminium flywheel. On the lawnmower they originally came off they did 4000rpm.

While a few flywheel explosions did happen it was much like the clone flywheels thing, one in a million.

I think we're pretty safe, just don't treat your flywheel like crap.

Thanks

Hayden

Never EVER full throttle an engine without a load.
You may get away with it a couple or even a few times...but why take the chance?
Putting a load on engines eases the internal harmonics.
Harmonics (for the most part) is what destroys rods.
Once the rod goes...wave goodbye to the block as well.

Maybe...sometimes warranties change. Then SOL.
Again, why take the unnecessary chance?

well i am seeing what different things effect the engine in what way... i pulled the governor, drilled the main jet.. messed with the linkages.. maybe ill do something to timing or throwing briggs valve springs into it.

i think im guaranteed a replacement though.

i ran it once with no load im going to get a rear wheel soon

...as long as whoever you return it to doesn't happen to notice it's been modified...

They wont replace it if they see you've modded it.

That's not a question. Mods void warranties. No questions asked means stuff like, "what were you using it for?" etc.
