Vile, I just took the photos today. Still got some work to go. I've got a 750 carb & should probably have more, but I've got some time in this one so I'm keeping it for now. Time will tell, I'm not sure that I'll know for sure unless I built another air filter bottom with the stock hole & changed the carb top back to a stock one at the track in a day. Who knows, I'm hoping to see it lean out on the air/fuel monitor at higher RPM's, that would be a start to think it is a positive gain. Lorne
