Got a nice lead (100 miles away) on a 1973 Tiger. Did some web research but still have questions for that model year. First, I'm only 5'6" -- barely tall enough for my dry-frame TR6 (seat height of 30.5"). Anyone know the seat height on a '73 Tiger? Was the tall OIF frame still being used in '73 or had it been lowered? Any special or major problems for the '73 750 come to mind? Both a 724 cc then a 744 cc motor were available that year. How does one tell which is which? Was it the '73 that had the infamous brittle gears in the 5-speed box? Any help appreciated.
