I took my bike down to the dunes last weekened and ran with my airbox off. I think some sand got into my carb and caused my floater to stick. I opened it up then closed it and now everything runs fine. SHould i be worried about sand still floating around in there?

 

If you haven't done so already, then take the carb completely apart and give it a thorough cleaning!
You don't want sand going through your motor if you can help it!
