The chain on these bikes must like to stretch. I had my chain fall off in the middle of an intersection, luckily I wasn't going fast. Now I'm paranoid about chain maintenance. :D
Chains are more efficient with delivering power to the wheel. Belts can handle plenty of torque but they also have trade offs. Even EBR has switched to chains on their new models.
Turn signals are pretty simple. There's two wires, black for ground and green/brown which connect to your turn signal switch. Green for the right, brown for the left.
I've ridden the Dragon twice and the Cherohala Skyway once on my CBR 250, might take the FZ6 down that way in a few weeks. Just take it slow and easy, the road isn't THAT tough.
