collecting the parts slowly to do a conversion during the hols. Thanks for the info. So the early cowling from the 126 won't do, because they used a dynamo tooo right? I will need to look out for the later ones then... I assumed wrongly that the 126 alternators as they had a "flange" that mounted on the side of the cyl block were a straight awap! I'm aware of the electrical mods. Many thanks.
So anyone out there with an alternator they wish to part with?
