A 42 pilot was the stock set up, so I have to assume that it runs ok with that.
I am not familiar with a NMUU needle. Stock is a NNSU. A 175 main is standard, so a 172 is way close enough.
Will the bike start and idle? Baby steps first.
If it won't then the jetting isn't the problem at all, it is a plugged passage or fuel supply into the carb.
