my cases were away for a long time and Ive worked on many bikes in the time. the '69 A50 being newer than the older ones Ive done.
q1.. the bimetal timing bush, should the inner flange be up against the inner cast face? I didnt remove or refit the new one... oil flows around ok.
q2.. the bi metal thrust washer on the timing side, presumably bronze side to crank face. Should it fit in the recess above the bush? This ties in with q1 as it will not stay in place . Ive measure the crank and inner faces for end float and there isnt any difference.
to answer my own questions...
good job I took pictures
