My 2012 F650GS pulls left when the rear wheel is aligned using the rear axle markers. To make the bike go straight when I pull my hands off the bars I had to adjust the wheel quite a bit to the left. In fact I am showing three marks on the top right scale and four marks on the top left scale. That is quite a difference. My chain slack is within spec. What is the best way on an F650GS to check that the rear wheel is aligned correctly. I am concerned that the bike may be going straight now because I just masked a different problem. Is there anything that I can adjust or check on the front axle? My bars always fall right when the front is unloaded but I suspect this is from the single rotor being on the right. Thanks for any help.
