Well here we are, halfway through March, so, the 400 was re-introduced to the wonders of daylight. Last use was late November. After checks on tyres/chain/battery etc., the petrol was turned on and left for about 2 minutes, no drips, OH JOY!. I had not kept the battery on charge at all, so, seeking forgiveness for all my past sins, it was ignition on and press the starter. Engine turned over about three or four times, and it only bleedin' started eh? Couple of trips round the block then back into garage to change oil and filter. Last time I rode it I had absent mindedly left a key in the steering lock, bad idea. So,as everything had gone well so far today that I dug out the new replacement I had bought earlier this year. My bottomless gratitude to all the people who have contributed to this forum on the subject of lock replacement, I wish you had warned me that I needed the Oxford Concise Dictionary of mechanical obscenities!! But I got there eventually. Thanks everybody, have a great weekend. Mike.
