http://www.readyracing.com/ This is a cool site and product. http://www.readyracing.com/products/readyfilter.html Click here to submit for the Big PiGS, because as usual they don't list them for the XR650L and XR650R's yet. But thy do have an Email request area though. I suggest that we all go in there and request they make filters for our XR's. "Pig Rider power of suggestion"
