a member has offered to sell me a front and rear hub off a 72 cb750 for my 74 cb750. in the picture i noticed there were spoke grooves in the hubs. i was just curious as to weather you guys thought these grooves would give me any trouble as i plan on powder coating both hubs. my thought way to get these blasted and coated and use stainless spokes and a new rim in black (if i can find some) any thoughts?
