I have a 2005 Road Star 1700. I complained about

I had the same issue with my 06 v-star custom. I changed the tire first because it was badly worn and even with everything else as per spec there is a great chance that a bad tire could mask other issues. It turns out that one of my front forks was lower than the other on oil. Once this was corrected there was no more issue.

Several options are available. If there is another dealer in the area go there. If not, take it in to the original dealer and tell them you want it fixed. Challenge them to ride with you with you as a passenger. Show them first hand what is going on and their obligation under contract to find and fix the fault. Be aware that they will probably try to respond " We have no control over how an owner rides his bike and the damage he may do to it while riding. As such the warranty will not cover repairs due to user neglect or damage." There is some validity to the statement. See what the warranty may say on the matter.

Okay, so the warranty doesn't cover it. What if a part were missing in the wheel assembly? In any event why can't his in house mechanic figure out what is going on? If no joy, contact the Yamaha regional manager. You can usually resolve issues that way. Alternate to that you could introduce the dealer to your two best friends> Mr. Smith and Mr. Wesson. :)

The front wheel should have a collar then an oil seal then a bearing on each side of the hub. The axle goes through the right fork, the hub, then the left fork. Bad bearings? Pull the wheel yourself and check. Any wear on the axle? Put your finger in the bearing. Does it turn freely and smoothly? Check the steering stem bearings and the torque on the stem crown nut. Any missing parts in the stem assembly? Are the forks operating properly? Check the forks for smooth, uinform and equal action. Both forks should act the same. If one is stiff and one is spongy then spook city can appear. Is the oil level the same in both forks? Has a spring in one fork collapsed? Measure the springs. Are they within factory specifications? How is the tire pressure? Are the forks mounted properly? Have they been twisted or knocked out of alignment? Is the wheel running true? I think .008 is the spec limit on the outside circumference and the same left an right. Somewhere in what I have written is your answer. If nothing else, the mechanic now has a checklist to work from.

I also have a 05 1700 Roadstar with the low speed wobble and poor handling in corners . It has never handled properly since new. Spent 5 yrs try to find problem as it was getting to the point where I wouldn't drive it anymore, cause it was getting so bad. Finally found the problem after changing wheels, tires and fork springs. The only thing wrong was the steering head bearings. They were in terrible shape. Apparently the specs for the torque is not enough for that heavy of bike. I had them checked at my dealer 2 years ago and they said they repacked the bearings and that they were good. They only packed the top bearing and obviously never looked at them and never torqued them, you could tell by looking at the locking nuts that they were done with a hammer and punch, not a socket and torque wrench. If your front wheel flops back and forth with no effort when on the jack stand it should have a "little" bit of drag, and I mean very little.New bearings and a "little" tighter fixed mine 100%
