I would like to know if anybody has put a large tank on an Rm 125? Im trying to put an IMS 3.0 tank on an 99 Rm125 for my son. The problem Im having is the shrouds and the petcock. The shrouds mount to the tank fine but were it mounts to the lower part of the radiator is off by an inch. the shroud can be bent a little to make it work but this puts a lot of strain on it. The petcock with this tank now sits above the magnito cover and seems to need a 90 degree type. If anybody has done this to there bike please reply.
