This is a rare one, found on the Minarelli P4 P6, Fantic Broncco, Harley Davidson Shortster, Harley M50, Harley M65, Gilera 102, and Indian 100 (I am sure I missed a couple)
The carb is rare, but the original metal air filter is even rarer. I have seen the filter go for $50 by itself.
It comes complete with the metal air filter, the Minarelli intake (originally on a P450 50cc 4 speed) and the throttle cable.
