There are no easy answers to this one Ralph so I suggest going with whatever is standard. I have had problems for some time with a conflict between the clutch arm and my right boot, both on the Square and the RH500. The RH500 is now much better after adjustment but if I tell you that it took me half a day to get the adjustment "right" on a bike I have owned and run for upwards of 30 years, perhaps you will see how sensitive this can be. So work to standards to begin with and adjust subsequently to suit yourself ( and the size / style of your riding boots !)
