I had to replace the plastic pull cord, and so I had to pull out the solenoid (actuator) to do it. I recommend you DO NOT remove the fender.
Here's an excellent DYI (which unfortunately wasn't available when I did mine):

For the REALLY tight work of loosening the two screws holding the solenoid I used a small bit that comes with a multi-bit screwdriver and and a small boxend wrench that went over the back end of the bit. Be prepared with patience, it's a very tight spot. But it can be done - if I did it so can you!
