i need to buy new main bearings for my crank and seen that you can get koyo bearings for 30.00 for the set but i was wondering what the quality of them is compared to stock or other replacements any advise or opinions would be greatly appriciated

i just dont want to buy a crappy product and go through all the time and money to build this engine and have a bearing fail due to poor quality

koyo is what is in the stock motor, i bought wiesco bearings and when i got them, they were koyo, but work great
