ima,
You just need to check the "fall away" for your neck bearings. There should be a slight resistance as you start to turn the bars, but VERY slight. I think it's like 2 or 3 lbs to start the bars moving when you pull on the end. You should find the exact measurement in your manual.
That's pretty normal with your fender supports and trailer. Everytime you have the tongue a little heavy, it's pushing down (and forward) on the fender. Did the same on my 01. I just drink my beer faster now, so the cooler gets lighter faster. Takes the weight off the fender! Those whoops are killer, aren't they! Have you gotten her airborne yet? When we rode it, it was raining so we had to deal with the calcium carbonate (I think) that they use to control dust. Man, that stuff was better than any grease I know of!! One time, the rear wheel started sliding to the right and it didn't stop until it went off the edge, where the saddlebag caught it from going any further. She tried to stop next to me, but slid about 75 feet on down the road. There was an inch of stuff stuck to her front wheel! It sure made for "fun" riding!!! I wouldn't have missed it for the world.
