I'm assuming you mean a 103. If that's the case, you may be looking at frame brace territory, as the gas tank forms part of the frame. Depending on how badly perforated the tank is, you may have lost a bit of structural integrity. Enough that you'll want to brace it if you kit the thing, as it would be all kinds of emberrasing to have your frame fold in two in the middle of a ride because of the weakened tank.
