You can be sure that you have an alignment problem.Another thing to remember is to keep the pressures up.(set cold)
One more thing--if the tires are cupping on the front-Your fork springs have probably had it or arn't enough pressure to keep the tire to the pavement.You'd be surprised at how many bikes (new ones) that come from the factory with to light of springs.A 1800 GoldWing is a great example- I went through this about 5 months ago-bike had 9600miles on it. Take a look @ Traxxion.com -they are not the only "game in town". Especially for our English bikes.
Hope this helps.
