Mikuni VM30 Question

that def doesn't surprise me.

You could probably jam a round jet into the needle jet, but I would simply replace the brass with genuine Mikuni parts.

I would speculate that they use different jets so they can argue that they are not copying a Mikuni product at all.  They seem to believe that changing one or two details allows them to argue there is no copyright infringement.

WHat impressed me was the casting and machining. Will they last or do they work, that's a whole other question. And I am not sure they fully appreciate the implications of some of the design decisions.  The loose needle jet for example would be a potential problem unless the main jet is pretty tight.

just run keihin jets. it was stated the genuine jet tubes were loose in the bodies so.. prob the only feasible option. or, retap the tubes.

I had a set of knockoff, and I mean DIRT cheap pwk 32s on the lightweight inititially.  they worked, but they had similar issues  . finally gave up and went with a set of pj34s I had laying around.  I like cheap carbs.. but there's cheap carbs... and then there's really weird cheap, cheap carbs.

I am not actually planning on using that carb for anything other than to see how bad or good it is.  For anyone planning on using cheap carbs, remember that Keihin jets are like large round jets in that the number represents diameter and not flow rates as hex jets are.
