You can add a washer or two between the stand bracket and frame on the clutch side to lessen the lean. I also have the 13in progressives on my bike and two thin washers made a big difference in mine.

I liked this idea , and if the bolts on the frame had been some longer, one could actually build up and get any lean you want!!!+
HOWEVER, the bolts only allow a spacer or two ....and it seems like there i not space enough to insall longer bolts eaisly?!!
Am I right?
