I mounted my horn just like Benji except I put a 90* bend in the factory bracket so it sits tucked up behind the headlight a bit more. Still have full adjustment on the headlight level in Vishnu's kit.
Thanks for looking up what size works and test fitting with pictures! I was just thinking about this as my bike was getting way to hot in rush hour traffic on Monday afternoon. Ordering a new fan was on my to-do list this week and you've just made it that much easier. :thumbup:
