Re: [St] Plug problem

[Al Garvin <agarvin@xxxxxxxxxx>]

Mark,
   Do you shut your bike off with the key or the kill switch? I have 
read that the switch should be used as this gives the system time to 
update the computer before all power is removed from the ECU. Also is it 
running at normal riding speeds OK. Not missing or spitting back when 
you roll off the throttle?
