Thats good, its therapy for me thank u ;) iam restaurating old bikes too, if you allow me some advice: the krankshaft need to balanceing it seems to be bent, it causes high vibration and damaging the alternator/gears/bearings. If u put the bearing in the case u need to heat up the aluminium, but this case is worn out . the bearing popped in freely. (it causes rattling noise) . And the last one change the upper rod bearing from bronze to roller type, cheap and it lasts well. ;)
