hi I have a gilera runner 125sp when I bought the bike the back wheel was slightly out of line I thought it was engine mounts so replaced them later I realised the frame rails on either side of the seat box are out of line hence why body panels don't line up so great is there any place or anyone who can help me straighten these frame rails up willing to pay name your price its not awfull because it passed a mot with advisorys for this
Easier to replace the frame completely. Had to do something similar recently because of the silent block mount being rotton. Not a bad job to do, easily done in a day
im quite sure you would need a frame jig to do it properly, like steve says, its easier to just change the frame.
