Right now, my machine is near stock with the exception of a K&N filter and the airbox "Wall" has been removed. So far the plug readings are good but are straddeling the lean side, but I'm going to be adding a second snorkle in a few days. I was wondering how much this would affect the jetting on the carbs. I know it should increase airflow pretty significantly, but I dont know by how much. I was going to buy a bunch of individual jets from the dealer here so i would be covered. Does anyone know what range of jets i should buy? I will more than likely be adding a pipe too later on. I dont know what the stock jets are, but I assume they vary by location of course. I'm at 330 feet above sealevel if that helps at all.

One more question, would it be wise to shim the needles at this time?

Thanks for your help in advance,
