i have a 2003 KFX 400 and find that when i am in the dunes, first gear is not enough for climbing the big hills and 2nd is to much and starts to bog. i need a sprocket that will fix that, any1 know what to do?

move one tooth down in the front or one tooth up in the rear it will give u some more power in 2nd to make it up the hill. I would change the front sprocker its cheaper.
