    Nothing wrong with the carb in question; the bottom line is, if it works, it works. That said, it's a Chinese "minkuni". Mikuni never made a 19mm carb. So, go in knowing this, along with what parts to source and where to source them.

    Quick update, I put the XR70 head on with the XR70 88cc TBParts kit and hi comp piston on the Z50 bottom end with no problems. Not that there should have been any problems lol.

    Fired right up and and scooted my 285lbs butt around the block for 10 mins with no issues!

    I just need to throw a bigger main jet in the carb and and I can continue to break it in.

    Thanks for the help!
