that is called tweaking. It is really more normal a lot more than you think.
just loosen the top bolt on the triple tree like another poster said and use something against the front tire to hold it solid. Do not remove or loosen too much, that is why I said the top pinch bolt, turn handle bars until straight but also make sure it is the triple tree not the bars. the risers could be off some to, like another poster mentioned.
It is really a simple correction.

 

sorry to hijack, but gotsta know what seat that is?

Ok I know it's been awhile, but here's an update. Jacked the front end up to take weight off the front end. With a black marker made a line on tree and fork, then loosened all 4 pinch bolts, raised and lowered jack so forks slide free in triple trees. Put it back at the right height and tightened bolts. Fork on left side was twisted, because the marks were off set on that side, also it felt like it went right into place.
Took it for a test ride and its where it should be, looks like it should.
