bike was bought new Aug. 2016. I bought it used Feb 2017 with 214 miles on it..runs hotter then most bikes I've owned so changed out the fan and removed the plastic veins in front of the radiator ....when starting to go for a ride the heat comes up to 7 bars on gauge....temp in 80's outside. when getting off interstate to my first red light the temp of gauge goes to 8 bars and fan kicks on then off...continuing on the bike stays at 8 bars and never goes back to 7 and fan stays off unless I stop again for another light at which time the fan will cycle if needed...is this the normal temp.range I can expect and when the outside temps start to be 93 avg. in summer is this going to change the engine temp?? I usually run about 75 to 80 mph on hwy to my destination 35miles away...also what are the symptoms of a blown head gasket as it happens ?? really enjoy this bike as much if not more then my 690 Duke
