You may recall my questions of some months ago. Strip of the motor revealed that the crankshaft had moved at the second cylinder giving rise to timing faults for cyl 2 and 3. This was probably caused by a hydrostatic lock from excess fuel introduced into the cylinder when attempting starting after 4 years of no use. Resetting crank at local Suzuki motor cycle shop, new rings and all seals and we have an as new motor that is a dream to use. Thanks to all who gave suggestions and possible solutions.
