Despite the presence of some notable members, the year did not produce an abundance of quality information. Instead, the
pickings are a little thin, which probably owes more to my move from a Unix system to a PC for collecting posts. You will find an occasional nugget or gem, there's some useful stuff on Amal Carbs, (always a hotly debated subject), information on unleaded fuel, the disappearance and reappearance of the sump filter on the 750, and increasing the power of the Commando.

Appreciation goes out to all the Brit-Iron stalwarts, with a special mention for Steven R. Schoner, John Mead and Ben English.
