I live in Spain and even if we have the ++30c summer i have heard the fan come on 2 times, the second time was just a idle test in my parking place after fixing a slight coolant leak from one hose, it was frustrating to wait 15min(after a long ride) for the fan to finally come on! But i prefer it this way, my ex- VFR800 was running the fan all the time even in the winter(and leaking coolant from under the rad cap until the bloody fan stopped coming on due to loss of coolant) what a crap bike it was....
If it was chucking out coolant with the fan constantly turning on then i'd guess your cooling system was clogged up!
Hi darssi!
the coolant system was completely flushed and new coolant + rad cap and still it kept doing it. Head gasket was ok. Its the "benefits" of side mounted radiators, they run hot immediately once you are in city traffic. seems to affect VTR1000's too. Being a big honda fan since the 80's i was really disappointed with the bad quality(reliability issues), slowness and high fuel consumption of the vfr800, i have owned 2 cbr600, cbr 900RR(super fun!), cbr1100xx,vfr750, vf500 and few Suzuki's and one Kawasaki..
I did lot's of searching before deciding to buy the Fazer, it's a budget VFR but in many ways much better! Down sides are horrific idle sound of the engine(mine has done only 24.000km=15.000 miles) compared to a honda and the cluncky gearbox.
I have managed to get 4L/100km= 56mpg and the relatively torquey 600cc engine is great, excellent bike for little money!
