I just put on new GNCC Holeshot rears and noticed that, though they are 20's, they are about an inch smaller diameter than the stockers. I thought about changing the gears from stock and going up a tooth on the front sprocket, but the tires are also heavier (6 pounds more total) than the stocks. So Should I re-gear or no?

The 07 400ex has a 14/39 gearing correct?

I know I should ride it first, I was wondering if anyone else had the same thing and what they did?

People are so misinformed about stock gearing.

1999-2004 15F/38R
2005-2008 14F/39R

The internal gearing changed slightly after 2004 too.
