Not really looking to mess this motor up anytime soon lol.. Wonder if I should get rid of my 4lb lower... or are they talking about ones bigger than that?

It's one of those things it depends on who you ask. Some people manage to make them live a long time others can snap it off without trying. It's a roll of the dice really.
The thing is when you run a bigger lower, you no longer have the support of the factory pulley cage that keeps the blower from tearing up the crank pulley and damaging the crank snout. Terminators put a TON of stress on the front of the crank snout.
