M2R 125cc

Had a size 15 pilot jet, couldn't start it without the choke and wouldn't idle good, they sent me a new carb with a 22.5 pilot jet and it kicks without the choke but backfires, sounds rough and has blue flames coming out of the exhaust, both 95 main jet.

What is the right sized jets for the yx125 engine and the vm22 carb?
I'm thinking the 95 main is alright and maybe a 17.5 pilot jet?
