When you buy a Demon you have to make sure you buy one that is set-up for your cam specs at .050 duration. A normal 750 Demon will not work if your cam has more than .240 duration at .050 it will run very rich do to the way the carb has been set-up. Demon has a chart that shows what carbs will work with what engines & cam profiles. So if your on the border you may want to go with the next bigger one they reccomend. Thanks Larry. Scott
