It will take away from your top speed probably around 4 or 5 miles an hour or so, But you will gain more low end, it will pull harder. Make sure you readjust your chain tension.

Make sure you mount the front Sprocket correct, I have seen lot's of front sprocket mounted backwards the Spacer Face in towards case's.
If you mount it wrong it will grind a large groves in your case.

you didnt say what the front was, and it makes more difference since its a smaller diameter.
