Replacing Solenoid?

[the chi]

Here's the deal:

Bike wont start.

Replaced the battery as it appeared the battery was just old and losing juice. Still wont start.

Turn the key, lights come on, the gauges prime, fuel pump primes, but when I punch the starter, I get absolutely nothing. (Other than the F1 light and some unrelated clicking). Kickstand is up, clutch engaged, tried in both neutral and in gear, so that ruled out the safety switch.

I stopped by the local shop to get their take, they think its the solenoid.

So, how hard is it to replace this on my own?
