I know that some of you, including myself have posted topics dealing with a lean that the FX140 seems to have on some machines. I don't have it on my 2003 FX140, but my friend has it on his 2002 FX140. What we noticed was that his 2002 sponsons were not equal in positioning. One was higher than the other. Mine were both equal. He adjusted his and it seems to have fixed the problem. Now I'm not a tech guy, but I thought that I would throw it out there.
