I have a 2011 RGC with Harley 19" front rim and 18" rear. Both tires are Harley Dunlop. I intentionally used Harley wheels and tires to avoid any problems with ride and handling. I also chromed the fork and when I did I asked the tek to replace the stock fork oil with Screaming Eagle oil. When I am riding at 70 mph or more the fairing starts to shake...the faster I go the worse it gets! I have dyna bead in the front tire, changed the front tire, going to change the fork oil back to stock today and see if that is it! Going nuts with this....anyone have any thought please? Thank you!
