Test if you need to adjust first.

On even pavement, with the clutch pedal to the floor, parking brake released, put it in first gear and rev up the engine to your redline. If your car moves your clutch is dragging and is causing poor syncro engagement. If it doesnt move then theres a good chance the syncros are worn.

If it is your clutch dragging, adjust it immediatly as driving it this way kills syncronizers.
