Is it OK to get a larger Injector than needed? Like if I get a 720cc with only 15 or 16g's. As long as I have a Fuel computer (would need ARC-2)?

I know running 450s with no controller is a bad idea, but if you could tune them down enough it would be fine. running rich really kills power, this I know fron experience.

Better to have too large injectors rather than too small. If you have a fuel controller, you can always tune it for the smaller ones.

The only place really large injectors are a problem is at idle. There's a limit to how quickly the injectors can spray so with big ones (like 720s), even their quickest (shortest duration) spray for idle requirements may be richer than you want.
