Fingers crossed that genuine FAG from other countries with genuine FAG factories, not fakes, are of suitably high standard. I've always used FAG or SKF bearings and hope that they will continue to serve me well.

1. Bearing fitted with RS seal only on the crank side
2. Torch used to free bearing hence heat marks
3. Bearing has been wiped after extraction
4. Wear in bearing noticed when oil seal failed and gearbox oil burning
5. Showed bearing to a 2 stroke motorcycle expert he agreed it was a faulty bearing
6. The two bearings were fitted in two differint bikes

Ok fair enough. Funny thing FAG bearings had two identical one marked made in Korea and one marked made in India. So if your confident you got the build right all to do is change bearing brand and see how it goes.
I once had a FAG Indian rear hub bearing off of a very reputable dealer, upon inspection it was clear it was way out of tolerance to the point that it was worce than the one i was replacing not only that it had patches of rust all over it, so yes definitely bad ones out there floating about.
