Easy start is an aerosol which contains "a mixture of volatile aromatics which ensure initial firing under artic conditions" basically you are supposed to spray it in the air intake of your car to aid cold starting, most autostores and garages sell it for about £3. its not curing the problem but working around it but it seems to work with my bike and it beats kicking it over about 50 times.Like I said I just spray a bit in the lower cylinder through the plug hole and it fires up in the first couple of kicks!bit of a bodge but it works for me!
