The Only way you can have the bike going straight down a straight road AND have the Front fork cocked to either side is if the "thrust angle" (thrust line) of the REAR wheel is not perpendicular to the rear fork & frame..
Checklist: Of course I am assuming your frame is not bent,, you don't have the incorrect spaces on the axles, your tires don't have a problem with them which is causing a pull,, your not compensating for road crown,,and your engine stabiliizer link is the correct length (front & rear rotors in same vertical plane). .
If the thrust angle of the REAR wheel is off, it will push the FRAME to one side while riding down the road.. The only way you would be able to make the bike go straight down the road would be to turn the bars a bit to make up for the rear Thrust angle.. This could be exactly what is happening in your case.
If the checklist above is ok, I would bet 10 to 1 odds, your REAR wheel alignment is off. If your bars are at 12:30 (aerial view) while going straight ahead, then your right REAR axle is more rear than the left side. Where the rear axle cams are means Nothing. Don't go by them.
