Hello everyone, I am in the process of restoring a 1971 Kawasaki G4TR 100 dirt bike/street. It has been in the family since it was brand new and I have run into a dilemma. The original carburetor was removed from it, and it has gone missing. My question is: is there any kind of universal carburetor that I can buy that will fit that model of bike? The original carburetor was a Mikuni VM19 sc, and to my knowledge, that carburetor has become obsolete. I've been extensively searching for that original model carburetor on eBay and I have come up empty. I would really appreciate if you guys could help me through this issue. Thanks.
