hey yo, sign on your aim and it will be easier to explain, haha
um it wasn't that difficult, but i had to make my headset bearings custom b/c no company will make a bearing w/ the inside and outside diameters i needed b/c the tolerances are SOOOOOOOOO close that every one says it wil fry, but their only steering head bearings, they move like 3 inches or something you know, its not like their being used for a wheel bearing or something. other than that i needed to make my braket for the 320mm rotor come off of the yz bracket in stead of the standard XR one that alot of people just buy a braket for and bolt it on, lol
