Hi All,
I have a 73 850 Commando frame which I'm hoping to use as a basis for my latest rebuild which will use a 72 750 engine and 850 'ANG' yolks.
I was doing some basic frame geometry checks and using an inclinometer and noticed the rake angle is approx 67 degrees whereas the factory spec is 63 degrees. I'm reasonably confident my measurement is accurate as according to the inclinometer the lower frame rails are sitting dead level on blocks of wood and the rear frame loop is also level.
There is evidence of some kind of repair on the lower frame top tube and I'm now wondering whether this frame can be salvaged as it might mean bending the rake back by 4 degrees.
I live fairly near to Motoliner Maidstone Kent who have a good reputation for repairing/aligining frames but before I go there I would like some thoughts on whats happened to this frame and whether its worthwhile reparing.
All info welcome
