Hard to say what is wrong without seeing it or knowing what was replaced.
If you removed or replaced the front wheel, the wheel spacer on the left is narrower. Having them swapped around will definitely cause it to track badly.
You can check the forks by taking an aluminum I-beam type carpenter's level and putting them across the two fork legs. (You're using the level for its parallel sides, not as a level). It should contact each of the fork legs at 2 points, all at the same time. If it rocks at all, somethings bent.
You can double-check the straightness of the front fork tubes one at a time by loosening the bolts on the left fork at the upper and lower triple clamps, with the bike on the centerstand. You should be able to grab the fork tube with both hands and rotate it 360 degrees with no tightness. (You'll need to twist them back down in the clamps to the proper height). Tighten and repeat on other side.
If the fork tubes are straight, the triple clamps should also be straight - they can only bend if the tubes are bent/twisted. I've never seen bent triples with straight forks.
