2013 HARLEY-DAVIDSON Flhtcuse

THIS MOTORCYCLE IS UNSTABLE AT HIGHWAY SPEEDS. I AM NOT SURE IF IT IS IN THE TIRE OR THE WHEEL BUT MY DEALER HAS TRIED OTHER FIXES, ALL TO NO AVAIL. FIXES HAVE BEEN MADE TO THE NECK BEARINGS, SWINGARM, ETC. THE FRONT END DOES NOT HUG THE ROAD AND ALWAYS FEELS LIGHT AT HIGHWAY SPEEDS. WHEN THERE IS NO TRAFFIC IT STILL FEELS AND HANDLES THE SAME WAY. OCCASIONALLY THE FRONT END WILL "DANCE" WITHOUT WARNING. IT'S NOT EXAGGERATED AND DOES NOT LAST LONG, BUT IT DEFINITELY MAKES YOU GRAB THE HANDLEBARS TIGHTER AND SLOW DOWN. WHEN NEAR OTHER VEHICLES THIS HAPPENS MORE OFTEN, IT'S LIKE THE FRONT END IS BEING LIFTED AND MOVED. THIS HAS ONLY BEEN HAPPENING TYPICALLY AT 60 MPH OR HIGHER. I HAVE NOT HAD IT OVER 70 BECAUSE OF THIS CONDITION. I FEEL UNSAFE TO TRY TO PUT ON THE CRUISE CONTROL AND TAKE MY HANDS OFF THE BAR TO REST THEM. AGAIN THIS ONLY HAPPENS AT HIGHWAY SPEEDS AND TYPICALLY ON LONGER TRIPS WHEN THE TIRES GET REALLY HEATED UP. MY FEELING IS THAT THE PROBLEM IS IN THE TIRE ITSELF, BUT I KNOW OTHERS WITH THE SAME ISSUE THAT HAVE REPLACED THEIR WHEELS (RIMS) AND THAT HAS SOLVED THE PROBLEM (BUT THEY ALSO CHANGED THE RUBBER AT THE SAME TIME). WHATEVER IT IS I WOULD LIKE IT TAKEN CARE OF SO THAT I CAN TRULY ENJOY MY MOTORCYCLE.
