1958 T110, completely refurbished, and with adjustable front dampers.
Over 45-50mph gently, over 60mph it weaves a bit more.
Not each time, but most times.
When it does not weave, I can start it weaving by moving around in the saddle, as I found out last weekend during some hard motoring up to Devil's Bridge.
Disconcerting yes, possibly potentially dangerous, Hmm!!, annoying certainly,
Does anyone know the cause and the cure.
Cheers. Mikey
