Hi,
I have 2 sets of float needle valves for my cb750 K5 that came from the original owner. I am trying to figure out which ones are most likely the original ones. I have included some pictures below, as you can see one of them has a "darker" almost brass looking valve and the other is smaller and rounded and silver. The "darker" brass looking one is slightly longer and sets my float height quite different than the the smaller one. Is there any way to tell which might be the original float needles and which are perhaps "keyster" or some other off brand carb rebuild kit? Thanks!
