Big bore is as easy as clicking on the Eric Gorr icon on the left.
A stroke is not as common a upgrade.
To keep the current rod ratio a stroker plate and custom cam chain will be in order.
You can make mid 50~s with a well built 97mm motor.
This will give the other built 450s a good run.
Falicon will probably do an offset crank pin as well as powroll.
