Had the same situation at 35-40. Read about problem on this website, but casually took hands off bars before thinking and front end went into severe wobble. Kind of scary if your now ready for it. Heard of varying degrees of satisfaction with local HD dealers service quality and didn't want to risk life, limb and my BSR on getting this taken care of on a "good" day. Was researching a switch from HD synth to Amzoil (didn't like the fact that HD uses 20W-50 in all the sumps) and was told about an ex-HD mechanic, that decided to open his own shop, and was a big fan of Amzoil. Talked with other HD riders and heard nothing but mega cudo's about him. He did the fluid change and told me I had a 5 pass swing in the front end. Told him about the wobble and he suggested I take it to dealer and get it remedied under warranty. I told him to go ahead and do the fix (while I waited). He also checked tire pressure and balance. Hit the road and the difference in ride and control was amazing. Worth every penny of the $150 labor charge. He mentioned some other simple fixes to make the ride even more enjoyable. Will get those done @ 10K. Nice to find someone that knows what they are doing.
