That looks just as it should. Nothing really beats the original Bocsh Monster headlamp on a Monster for looks and fit. Just a shame about the reflector and lens not being up to much.
You should have a good set up now though Geoff, with the Cibie H180 and adapter.
I still haven't tried my Cibie out in the dark yet!.. but it's dry and mild and I need to empty the tank.
Nice job Geoff.. Bike of the year just gets better..
