I´ve shelled my inner primary as well as tranny bottom bracket. I´m having a difficult time finding another inner primary that matches up and I can´t even locate a part # on the inner primary.....I´m pretty sure it´s a 60441-79 (not positive) but I can´t seem to find an exact match with the primary chain oiler tube which I do want to continue to run. Any helpful advice would be appreciated!! Y141972@aol.com
