ImIf my bike wont start but does start when I use the wrench on the solenoid trick; does that mean I need to replace the solenoid? I'm having trouble working this out as ImI'm new to mechanics and trying to learn. If this is the case some people say its not the solenoid and its the starter relay. I cant seem to work out the difference because if you search for motorcycle solenoid parts and starter relays they look exactly the same. Any advice?
