I'm looking for some help.
I just got a set of XR 750 cams that I'm going to measure and start reproducing. I would like any information on these cams that anyone can give me as to aprox. date, who they may have been made for, what racers may have used them, what type of tracks they were used on, and where they fit into the XR development history.
These were made by CR Axtel, with lobes welded to the gear clusters, all lobes are stamped 055, one of the gear clusters is stamped on the lobe side "79" which I am sure is factory stamp and is preceeded by letter? "I" or "J", hard to tell because weld starts to overlap.
Thanks for any help,
