350 Rancher Steering problem

Okay so this past weekend I converted my TRX350TE to a TRX350FE. Well before I did the conversion my bike went completely straight down the road without even having to hold the bars. Well after I got everything bolted on, one of my tires was tied in so far that I could only turn the bars in one direction. Well I adjusted it out straight. But now when I go down the road the bike pulls really hard to the right, and if you don’t hold the bars tight for even a second it will turn right so hard it will almost flip in the road.
Any ideas?
