14/40 = .35
15/40 = .375
14/38 = .368

Dropping two in the back will put you in the middle. Adding the 15 will yield the largest gain but unless you have some extra HP in mods, The 15 might not do much. If it's stock I would do the rear.

P.S. Are you really a member of your local 81?

I would try a 15 up front first. The front is cheaper to replace than the rear. I think the 15/38 would be too tall for the Z. IMO

it wont be stock when i change the sprocket, just a filter and a pipe tho, idk if that would be enough. And no im not a member, just love harleys, my dads had all different types since i could remember, cant wait to get my own

hey i have the stock gearing on my 04 KFX...when in the dunes i am finding that first gear is to low of a gear, but second gear has to much and bogs me down big time. What would you guys recommend for front sprocket? btw i have a pipe and filter done to it and sand sharks..
thanks alot!
