I have a 2007 Yamaha XT225 that i got a flat tire on last week. When I trailered the bike home, I noticed a second hole the size of the first valve stem hole, but with nothing in it. I could see the rubber wheel strip on the inside of the wheel by looking in the hole. I have been riding since 1968, and I have never seen a wheel like this before. Is that supposed to be there? What is it's purpose? It's been a while since I have had to do this, but I'm going to get a pair of spoons, and replace the tire and tube this weekend. I HATE not being able to ride !
