Hey guys...I have a Foreman 500 ( Wife ) and a Rincon 650 ( Mine )...and both of them are snorkled...If you do not pull the air box plug..or shut off the fuel..the air box will fill with gas. This happens because the wind blowing by the snorkle while traveling causes a vaccume. This vaccume will pull gas out of the carb into your air box.... If you travel for a short period of time, this will fill the air box with gas and reach your air filter. Trust me...when your bike wont start and you open your air box and your air filter is melted ( this is what happens when you put foam in gas ) you will be looking for a parts store before you can ride again. Just a little help ...
