Hey guys has anybody been having trouble with front tires? I bought the bike last year with 5400 mi. The front tire was all scalloped so I replaced it at a local shop. I put about a thousand mi. on last year mostly back roads. This year I take the bike out on the highway for a spell and the front end shakes up and down like a bad shock on a car between 60-80 all is clear above or below. I was thinking wheel weight so I take it back to local shop who said my front end and newer tire are junk. I had them rebalance the tire and have not been out on it yet. 50 miles/ hour winds and rain. last three days welcome to new england. Thanks in advance for any help.
