I have a friend that use-to-have a 1997 Goldwing Champion trike. After only about 30,000 miles, the driveshaft u-joint broke and caused other twisted damage to the driveshaft. He tried to get one covered under warranty, but Champion would not offer any help. He had to purchase a new one from Champion for six hundred something, and ended up installing it himself. On a 1500 driveshaft replacement, you must remove all the bolts holding the rear diff, and slide it rearward. This was the instruction from Champion itself. That trike was fixed, later sold, and now he has a gl1800 Champion trike, without any problems. I also have a gl1800 Champion trike, that has never had any problems, EXCEPT for the constant noisy rear pads that seem to never go away ( this problem is actually listed on their website, but Champion still wont stand behind any repairs ).
