There are many ways to make the max quicker if you want to bend the rules. You dont even need to buy the DD2 cylinder to do that. The end result is always IT IS ILLEGAL and would lead to disqualification if you run in the Max Series.
If you are thinking of doing the mods for open class, then the moded engine will still not be as fast as a true blue 125 TAG engine. So why bother? Go and buy a proper engine for the open class. That way you will have a good reliable engine.
I do not know what rules are used in Australia but in Malaysia we are checking on all this illegal items now.
