I screwed up the carb slide on a 1980 DT175G and can't find a replacement aside from entire carbs from China for $22. I would be willing to pay for an OEM real Mikuni but they just aren't out there. Anyone tried one of these Chinese Mikunis? I Chinese stuff is junk, so no need to educate me. Just want to know if anyone has bought one of these and had it work or not.
