Front End Feels Loose

Started noticing this season the bike feels loose. Started noticing it at highway speed, but under 60 it felt good. My chain and sprocket were in pretty bad shape and making noise, so I replaced them and rear wheel bearing. Now the problem seems to be worse. Front end tends to wander, even at lower speeds now. Does anyone have any idea what this could be? Also have put the forks up an inch through the trees, and installed 11.5 inch shock from the stock 13.5 shocks. Could this affect the tracking of the bike?
