Since I posted the tools and items I used to lower the G310R, I have returned to its factory height last weekend. My daughter is now tall enough to not need the bike lowered. The only detriment we have found with the lowering is the side stand stability, causing one tip-over to the right hand side.
The only handling difference in the 8000 miles put on the lowering link is the lean angle. In either position, the bike is more than capable, with the stock tires, of leaning over far enough to fold the foot pegs upward.
Give a man a milling machine, a lathe, and other dangerous tools and he shall create the greatest pile of useless chips ever conceived.
