I'm not sure about a power kit. If you had a pipe with it, it'd be a great upgrade though. I'd get that 14t front back, cause in order to get the back sprocket on/off, you have to take off the wheel, and unbolt it, and i think you might have to take the hub off too. My 14t front was a bit too big, it hit on the case saver, so i got out the metal grinder, and ground it down just a smidge, and it fit fine, and works great!

if its a 300ex, you should only have to take off the wheel, I dont understand why a 14tooth was too big
