Hi, i've completely rebuilt a beautiful MC16 but when i first started the engine, in about two minutes, the clutch side bearing broke its ball retainer and the engine stopped. Now i need to replace all the three bearings but i can't get their part number or brand because the ones my bike had where machined to the required size and then got erased the numbers in its sides. I've searched thorougfully in the site but got no data about it. would yo be so kind to help me with this? i'm in argentina, we can get here koyo or ntn bearings. thanks in advance.
best regards
M.
