Rich Oliver’s Mystery School has a fleet of 40 Yamaha TTR’s for you and your friends to ride. Lindemann Engineering has been one of the sponsors since it’s beginning. That’s a lot of fork and shock work. Here’s another rebuilt and re-valved shock about to go back together. Rich has been doing his Mystery School thing for some time now. One of the behind the scenes tricks is to have extra forks and shocks ready to go so a leaking seal does not leave him short of rides. This lets me do my work in batches.
