Well, you made the first step by purchasing both operator and shop manuals. They will tell you about everything you need to know. The track tightner is just behind the front wheel. Loosen the lock nut and then tighten the track adjuster. If you are lucky there will be a crooked looking open end wrench in the tool box under the left side arm rest made specifically for adjusting the tracks. Lay a straight edge from the rear sprocket to the front wheel on top of the track. Tighten the track until you have 2 inches of droop in the track halfway between the front and rear. If in dry conditions you might want the track a tad tighter. The steering will not be affected by the track tension. wait until you get your manuals before fooling around with the steering adjustments.
