You can syncronize those with the weber style ( and mikuni) sycro tools available on Ebay for about $30. It measures air flow from the air horn and is exactly what you need if v boostvdisconnected and left open, or running dynojet stage 7 with connect- tubes. I just did mine, as i had the same problem, and the syncro was the problem. Mine looked close to look at, but was WAY. Off! Buy one, you wont be sorry!
