Hey guys. I am so disappointed. My Duke 200 has so far clocked 30,000 kms. I take care of her perfectly with regular oil changes, quick fixes of oil leaks, chain lubes etc. Recently I started hearing a knocking kind of noise. I took it to the SVC. They said my crankshaft bearing are gone and the crankshaft has to be replaced. I am not worried about the cost. I am worried whether the bike will ever be the same after opening the engine. Generally there is a saying that once you open the engine of the bike, it will forever keep giving you trouble. I am worried my bike will constantly be giving trouble now.
I am feeling very anxious. I did everything right and still I feel like I will lose my bike

Will the bike be fine after replacement of crankshaft? Without recurring issues or power loss?

Sorry for feeling so much. Would be very nice for any help or advice or experience.
