I had a similar problem with my yellows. Try taking off your booster, or replacing it with a 2 bolt. You bite will increase but you hold may go down abit. Then regirnd your rim with a thin disk.
Haha, i recon you should just keep welding it.. Until the point that every tube has a plate on it, every weld has a new weld on it. That would be funny, and guessing it wont take too long as it is Rockman.
