So I let go of the grips, bike is in gear, above 40 mph, and as the bike decelerates, the front wheel starts to wobble and gets worse the longer I leave my hands off. I, and another guy who use to run a shop, have gone through the front end; checked the tire, checked the wheel, checked the forks, checked the steering head. Looked for anything obvious like mis-alaignment, bent forks, weld breaks, bearing stick or slack, and it all checks out. Changed out the tire and balanced, checked the wheel 4 straightness or damage and wheel bearings, forks are straight and fork brace is correct, no play in the steering head and no broken welds. When you are riding the bike the steering is same as it ever was since new, the bike tracks through corners, there is no stick or grind when turning, and the wheel stays stable on acceleration and deceleration, as long as you keep your hands on the grips. Take them off when decelerating, front wheel wobble and head shake. Any thoughts?
