TYteam

Hi, We have a recently restored TY250 ('78) that I am trying to register for road use too. It now has an MOT and I am struggling with some technical info to complete the DVLA forms, to hopefully get a sensible plate for it. Please can anyone help, if there was a workshop manual available for this bike then I am sure the info would be in it. We also have a similar age TY80, Haynes do a manual for it, does anyone know of anything similar for the TY250? Yours hopefully, Grant & Oliver.
