Also,on the first set of 3/0 in rear,they are gonna rub the inside of fender for a short while. It isn;t much,but the fender has to rub/wear at first on inside in spots. Second set,no issue. You can look inside of fender( rubber) and see shiny spots.I also moved wheel over when aligning chain/sprockets. I put a dab of vaseline on the spots the tire rubbed,issue was gone quickly after that. Actually slowed bike down when off throttle coasting. Could feel it grabbing. Get thru it,it is very much worth it. Mass produced plastic parts with variable tolerance. Ride it,it will fix itself.
