I just got a brand new uncorked 2002 XR650R, my first bike in many, many years. Boy do I love this red ape! How old am I? My last bike was a Bultaco and this sure ain't no Bultaco. I've been riding mountain bikes for years and they (the party poopers) keep associating them with motorcycles anyway so... I am back and the Trek is now hanging from the ceiling. I am now "complete" again. I plan on licensing the beast to justify the cost of grandpa's little red trail bike. Only a horn and brakelight are required in Colorado and they are already installed. I am also installing an enduro computer to see just how fast I really go. However, I want much better lighting. How many watts can I drive with the stock coil? Can I bump up the feeble 4 watt tail light without melting the lense? What types of lighting have you guys had experience with? Thanks for your help. Bob.
