[QUOTE="Rich Rohrich, post: 1286269, member: 16241"] Of course it's going to suck in dirt. It's a tube that is open between the the atmosphere and the internals of the carb. Think about how a carb actually works (atmospheric pressure PUSHES fuel through the jets) and it's clear that unless you filter the air (and you have to do it without causing a pressure loss or you are going to change the fuel curve in a BIG way) you will always pull in some dirt via the vents, and it's always been that way. Two-stroke or four the carbs all work on the same principle. This is nothing new. The good news is it's usually only really fine dirt that will get passed as there is only a small pressure differential that exists in the carb and the actual flow is minimal. Guys who ride dusty areas tend to have the most trouble with it. [/QUOTE]
