Took the B20 in for a few things. Exhaust gasket had let go, luckily had a spare, easy fix. brake adjustment, seems like it always wants this. A few cables to be tightened.
Most interesting was adjusting the rear shock absorbers. Thanks to William Corke's posting on the LMC site, we were able to find how to adjust the shocks. He showed where the little adjustment tab was on the shocks, under a little cover, and settings varied from fully closed to two turns open.
We tried one turn as a middle setting, and it was way too soft, so in the end, we settled for just 1/4 turn open on both sides (one had been fully closed, the other a bit open). The change was lovely - the car is back to its comfortable, but informed, ride and no more jarring over rough bumps.
Key to this is also setting the tire pressures. Too often people think firmer is better, and set them at 30psi. The real setting is 25psi, and the sidewalls at this setting provide part of ride comfort. Its important to those of us who live in cities, with our less-than-perfect roads. Set right, the ride is just right. One can always firm things up for the high speed runs on smooth country roads.
All good for now!
