magnum rev box

[fast4Exr]

does anybody know anything about a magnum rev box. anybody use one on their own quad. should i keep it on or take it off.

I have had one on my bike for 3 years, very good rev box no problems starting in the cold.

From what i have heard, if u have a lot of motor mods, rev box is perfect for you, but if u only have slip on, air filter and small mods like that, then having a rev box on stock motor isnt good.

all i have is 400 motor, white bros e2 pipe, stock air filter, could this rev box be a reason for me to be fouling plus, or would it be a cause fo me to rejet my carb?

I am not sure but I don't think it would cause you to foul your plug and I don't think you should have to rejet. You should have however rejet for your slip on.
