My bike will never be on the street.. so things that benefit street riders (like a coasting enricher) are of no use to me. Hopefully, I'll never be coasting.
Also it seems like this may make it more difficult to fine tune the a/f mixtures screws. Rev it up and see how it comes back to idle but this adds fuel, making the mixture not entirely dependant on the a/f screw setting.
Or, does this thing only come into effect during engine braking?
