Leaning to the right

I'm tired of taking my bike to the dealer, since no one can find the problem. Earlier this year I was out riding and doing some good cornering. I noticed the front end got soft in a tight rough corner. When coming home on the interstate yesterday I noticed that the bike seems to lean to the right when going straight down the road. The left side of the fairing is higher than the right side. I know the bike hasn't always been like that but trying to convince a tech is almost impossible. Seems that the bike should be level when riding down the road when not cornering. Could I possibly have a weak or broken right fork spring? Has anyone had a similar problem? Should have had the dealer install new progressive springs when the fairing was all apart. Any help would be appreciated.

I haven't had anyone do service on the forks. No leaks either. I haven't checked the rear shocks for leaks. If one shock has a leak will the air leak out for both shocks? I was wanting to install progressive springs in the near future but am worried that the job is over my head. Thanks for the info.

I had to rebuild the front forks on my sporty after the run in with the van. It isn't terribly hard at all. Like Chuck said pretty straight foward. Having a good graduated measuring device (mL pref) is quite helpful. I knew that graduated cylinder I snagged in college would come in handy someday LOL. I went to the heavier oil too and improved the ride a bit.
