20 minutes is not a lot of time to spend working on a crankshaft.
If the workshop only spent 20 minutes working on your crankshaft, then I suspect that they only replaced the two outer main bearings.
I would expect it to take at least 90 minutes to replace all 3 main bearings. Even 120 minutes is quite quick.
Right ! 20 mins is rediculous, But how to rebuld it ? Someone knows the process of making NSR250 cranshift?
