Sorry Ron I'm doing this just so this will stop. I don't have time to look up the Trinity Bell that you're referring to but a lot of these have been approved. So the deal is you can approve aftermarket parts or accessory parts and if you choose to put them on your motor the approved parts are legal. You may notice there are a ton of rotors that have been submitted as aftermarket parts for Motors and they are perfectly legal to install as long as they have been approved for that motor. Often these rotors are submitted long after the original motor approval. Beyond that as was stated before it's hard to police someone building a motor from parts versus a factory motor sold over the MSRP. And honestly this is only my opinion and not anyone else's or any organizations if you're in Australia you can make your own rules. If the situation is that problematic for you then you may want to ban the motor. Roar has enough problems without fixing the entire world's problems.
