DynoJet Question for 300ex

[texags]

I have a 2000 300ex. I'm installing a FMF Powercore IV exhaust on it and I'm also jetting the carb. What is the power difference by using the Stage I (w/ the airbox lid on) vs. Stage II (w/ the airbox lid off)? Also which air filter should I buy besides the stock air filter? Finally, what other low cost improvements could I buy to make the 300ex faster? Thx for the help in advance.

I have a UNI air filter and so far it is awsome. As for more improvements get some different size sprockets and a rev box that should help. Also a high compression piston would help it out but might be pricey.

I don't know if its a huge difference, but since you got the jet kit, it's free horsepower!

if you are also in need of jet size, i have supertrapp pipe, K&N filter and a 11:1 Wiseco piston and as of now, I have a 116 main with eveything else adjusted to what dynojet suggests and it is right on the money. This is at sea level by the way.
