Pulling to the left?

[2000gtallout]

Hi everyone, ive got a 98 750 katana. I recently have been rebuilding it, now once i have got it on the road i notice it pulls slightly to the left at speeds of about 60 mph +. My question is, could this be caused by the tires? Possibly because of it sitting for about 2 years not moving?

I couldnt find a single bend or scratch on the frame, so i figure something else. Any thoughts?

Short answer, yes.
Long answer, yes it could be caused by the tires, either normal wear or broken belt. Could be the rear wheel is out of alignment, could be you are sitting on the bike lopsided (stop sitting on your wallet), could be the forks are tweaked, could be a bad bearing, could be a bent swingarm, could be a bent.... and the list goes on. Start by checking the rear wheel alignment, it is the most likely culprit.

When you say "pulls" what do you mean? Do you actually have to keep pushing on one bar end (or pulling on the other) to keep it straight? Or do you mean it drifts when you take your hands totally off the bars?
A wheel alignment issue is often only felt when doing the hands off check, whereas a "pull" that you need to constantly fight the bars to keep straight is indicative of a bent or broken motorcycle.

Considered a sticking left caliper?

My bet is the rear wheel alignment. How are the hand grips? If one is slightly bent it will aslo cause a feeling of a pull.

It is just barely pulling if i let my hands of the handlebars. Its not bad at all, but i just wanna make sure it gets fixed and doesnt get worse.
