Default More low torque and pull from a JR50--How?

OK, my 5 year old raced for the first time this weekend and loved it! It was obvious that the PW riders were smokin' the JR riders off the line.

What can I do to give more low end pull and torque? I see a 33 tooth rear sprocket by Moose (M640-21-33) but cannot verify that it will fit. I also am considering a FMF spark arrestor (FMF 023039). Will this work?

Any other mods suggested without engine work? It's a 2004 under warranty and I cannot change the engine due to MX rules for the PW class.
