THE ONLY REASON THEY NEED MACHINED IS TO REDUCE INSIDE DIAMETER FROM 20 MM (stock on 650r) TO 17MM (stock on 250r). Tell him you need some bushings to reduce the inner diameter to match your axle. Just bring the axle along with the parts to him and tell him to fit the two.

Many people will misunderstand when you say the bearings need to be
MACHINED. It is not possible to reduce a 20MM diameter bearing by machining it; however, as you stated, you can insert the appropriately sized bushing, which will reduce the inside diameter. Or, you can just buy the ready made bearings that have the same OD (of the 650R) and ID (of the 250R)!
