No there's not. Bigger Cyl. and Pistons about it. BTW. That's how the Org. yanmar roll over happened. Killed a kid! Linkage stuck Wide _ss open trying to get more power. Good luck and hope you don't get anyone else killed!!

How much financial and health risk are you willing to take ? Being able to roll coal is a terrible reason to want to do that. Out of curiosity, how old are you ?

More grunt? Replace it with something larger.

More grunt would be to add wheel weights, increase traction. Messing with the fuel on a diesel is a good way to have it come apart. Can you afford to replace the engine?
The best way to get more grunt (work!) out of a diesel is to let it work longer, not faster. Slow and steady for long term is a lot better than a quarter mile run before the engine blows.

I honestly doubt those little 2 cylinders would stand much more fuel. You blow that motor up you're screwed. Parts will be hard to find. But if you have a boat and need an anchor you're in luck.

To get more grunt out of the machine is to swap the DIFF gears and up the tire sizes.

Basically, a YM146 is a GT Garden Tractor. It's not a racer. Although there is a YM3000R racer out there.

The YM3000R, you'll need a racing helmet like robin has here,
