Thanks for the help hb7. I did find a few monster headlights, of course they're pricy but a good option and a good lead. I found a reference to replacing the lens on a Monster with a BMW R100S lens (part no. 63121358147).
Anyone know if the lens can be seperated from the reflector on the Tour or is it all one piece?
Addition info for those who are interested.
In the following URL is a list of partnumber for headlights.
