Anyone ever done it or know how to do it?
I would buy a socket but don't see enough space looks like cam chain adjuster would be in the way? Can you remove the thermostat housing and do it that way, I am really lost on this one!!
Thanks for any help

(can I just leave the fan wired to run all the time while I sort the carb problem out? But I would rather fix it)

I think it's by the thermostat on the right side of the engine low down

Thank you!

just wire a feed from the ignition power to the fan via a switch and inline fuse. put the switch somewhere easy to reach while riding then you can put it on if you want too, no need to have it running all the time and if you power it after the ignition it wont be able to run accidentally when the bike is off.
cost about 2quid for the bits!

Yeah I thought about this but.the temp gauge is not accurate either so I have bought the sensor but cant see a way of putting it in!
