I have an 1986 90 and a 1955 S1 currently being rebuilt after spending 43 years in a barn. With the current situ I am spending some time on the 90 to bring her back into shape.
As always, plenty to do. No spannering experience so it is all fun and games. Currently have a broken rocker valve and duff hand brake. And leaking pipes. And leaking gaskets. and ....lots pf parts on order.
