try one size up on the main jet and one clip lower on the needle.

Put the baffle back and don't waste your time. That's the easiest way to solve the problem. Why did you take it out in the first place?

probably to make it louder. Correct me if I'm wrong, but the baffle creates good backpressure? right?

I can't think of any good reason to take it out. If you are wanting to try to make it faster than you bought the wrong bike to begin with and taking the baffle out, won't really make it any faster anyways. You're just going to annoy the hell out of anyone around you.

The backpressure is there for a good reason RM85rider123
One of main reason is so that you don't burn out your ext valves
