Personally, I have never noticed heat coming from either side of the engine. 🤷♂️Being new to the FZ 09, I noticed what seemed to be more than a usual amount of heat coming from the left side of the engine and really warming up my foot and lower left leg. Is this a FZ thing?
Good question. I haven't had a water cooled bike before (Harleys) so I'm not familiar with the fan operation. What is normal operation with that? I know what it is but when will it come on and cut off normally?OP, are you feeling a current of air like maybe your fans are running?
Holio, That's what I was trying to get at. If I'm moving at speed, is that enough to keep the temp at a level where the fan is not needed. How are ya'll getting the cut-on-off temps by the way?2018 MT-09 here. My fan starts at around 219F and turns off at around 215F. So it does not matter your speed. What matters is engine temp. If you reach that threshold temp, the fan will turn on. Once it goes bellow the "off" threshold", it will turn off.
So unless you are riding in ridiculously hot weather, at 35mph, there should be enough air flow to keep temps well below 200F and it will never turn on. I only get my fan turning on at city stop and go traffic. Any steady speeds at or above 35mph and my temps never go near the engagement threshold.
With an ECU flash, it is possible to change the on/off thresholds, so if yours has had an ECU flash, take that into consideration. I'm thinking of flashing my ECU solely to adjust these temp thresholds as I think they are unnecessarily high. I would much prefer using the crap out of a fan and replacing that, than having some major engine component fail due to high temps.
Wait till you ride something like a Duc 899 in traffic. I swear I could smell BBQ.
