You CAN run points on larger setups with aggressive pipes AND successfully manage temps on a 70cc puch.
I can't speak for anything larger than that but I've been running points and a mini rotor on 2 70cc weekends puch reed kits MLM pipe hi comp head.
I also have 2 TCCD 70 CC kits with MLM and treats pipe one with points again never a temp issue if it's all setup right which isn't difficult on a puch E50.
