Connecting rod bearingsss

Anybody got experience in changing the connecting rod bearing of a gy6 50cc engine ?

Backstory: this is a specific setup with a 105cc cilinder ported cilinder head and a 24mm carb all the combined put a lot of pressure if not double as from stock on the connecting rod bearing, changed my oil today guess what full with gliters part comes from the new cilinder breaking in I get that I just need to change to rod bearings in advance to quality ones that won't break with this setup and also possibly a stronger connecting rod, on the other side I'm thinking about putting a gy6 150cc crank in there idk help, tip anything really
