Let me break it down for you. A genuine Mikuni is
JAPANESE and you're going to pay a fair amount for it, however, the knock-off's can be good if you go through them before throwing them in whatever application you desire to put them in.
Please watch the video link I have placed at the bottom of this post. It's from a channel called "Jennie's Garage." Jake, who runs the channel, is a great DIY mechanic, and a bit of a cheapskate, but it's really cool to see how he works around some issues too.
