Possibly, but not all that likely. The fan load is the only thing supplied by this fuse (which is number 6 - brown 7.5A) and shouldn't really affect anything else. However, if the fan relay is goosed (and causing the fuse to blow) there is a slight chance that other circuits could be affected as the relay's positive trigger feed is linked to the start inhibit system, dash, coil etc. and the negative is switched by the engine temperature sensor via the ECU. The internal diode (connected in parallel across the trigger +/- takes up the energy stored in the relay's coil when current is removed. Without the diode, that energy has no place to go and will cause a potentially damaging voltage spike.

Firstly, are you absolutely sure it is fuse #6? If it is, then what I would do is pull the fan relay from its socket and see if the bike runs without blowing the fuse. Obviously you don't want to be riding in traffic without the fan in operation and keep an eye on the temperature warning light. (If you can get hold of a diagnostic tool you could run the fan relay test.) If it still blows without the relay in place then there'll be a wiring fault and a short to ground somewhere. You'll have to trace the wiring and see if you can find anything amiss. If the fuse doesn't blow, then refit the relay and try disconnecting the fan and see what happens which should tell you whether the fan or relay is at fault. As I said though, I can't see why the fan itself would cause a non-running situation.
