I have a 99' 400ex and it's time to change the sprockets and chain. Stock is 15/38 for the sprockets and 520x94 for the chain. If I go up to a 39 tooth rear sprocket, what do I drop the front one to? 14 or 13? And does that mean I use a different size chain or does it stay the same? I'm looking for a little more low end power. I just installed a white bros. e-series w/ curtis sparks header. Any suggestions?
My tires are 20" rear and 21" front. If that applies.
