How important is it to rake the trike. I just bought a 2001 GoldwinG with CSC conversion. There is significant shake when I decelerate especially going downhill. But it is manageable. Now the previous owner put 100,000 miles on the bike. I am not sure when the conversion was done. But what is the danger of the shimmy versus the wear on the front tire?I don't feel a loss of control when it shakes but it is a little disconcerting. What's your opinion.
