quick question

[400exrider0004]

I have a 2004 400ex and I wanted to drop a tooth in the front to make it 14. The company I wanted to get the sprocket from didn't have 14 so I was wondering what should I do with the rear sprocket. If dropping a tooth in the back is like dropping 2 in the front(not sure) wat should I do to make it have the same differnces of dropping a tooth in the front.
I want more torque for drag racing.

You got it backwards....two up on the rear is about the same as one down in the front.Actually about 2.3 but thereabouts.Fronts are generally cheaper and easier to change out except when ya go up on the fornt and have to axe the casesaver..not a good idea.:ermm:
