2009 RINCON viciously pulling right

hey guys, I just purchased a used 2009 rincon, it has aftermarket rims and tires on it and a 2" lift kit, when I rode it the first time I noticed it was pulling right while riding and worse on deceleration, I took it home took some measurements and made small adjustments to the steering arms and it rides nice and straight now. Unfortunately its still pulling hard to the right when I let off the throttle. I checked all the obvious things such as brakes rubbing tire pressure and bearings, everything is fine. then I got the idea to push down on the front of the machine and bingo when I push it down the left wheel stays straight but the right side turns to the right, that explains it because when I let off the throttle the nose drops and pulls me to the right. has anyone ever had this problem and does anyone know what causes it? I’ve checked everything and I cant seem to find anything that doesn’t look correct.
