broken choke lever

[bluehose2012]

hi, my choke lever broke. I was able to start the bike by manually holding the cable. I'm in search of a replacement-apparently I may have to change the whole left sided housing-the lever comes with the housing, $100 unfortunately.

how hard is it to change the housing? will have I have to mess with the clutch and electrial stuff. I think changing the choke lever is easy but I'm not sure about the rest. will I have to remove the grip?

thanks in advance.
