I recently acquired 2 750 Hondamatics 1977. They were in dry storage for the past 25 years. I got the engine running on one of them but I can not get it to shift into gear. I tried to move the shift lever on the other bike also with it not running and I can't get it to move into gear either. So what am I not doing right to get these bikes into gear??? Both bikes were in neutral when I got them and I am NEW dealing with the Hondamatic. Thanks for any information.
