I have a 2002 wide glide that I put 55,000 miles on. Been as far west as WY, and as far east as Detroit. Your bike should have a cruise on it so to speak. There "should" be a set screw with a large knob at the bottom of the throttle, just screw that up and it lock's the throttle in place. Not the safest, but I have done it. On my Ultra, I blew the fuse for the elec cruise just outta Chicago and rode to Gatlinburg TN with out it.
Yes we ran the dragon. The photo with the logo on it is take on the dragon by one of the three companies that sits there all **** day, taking photo's on the off chance you will buy them. **** of a way to make I living I think, but it must work.
