04 running hot, looking to cool it down
Honda sells premixed coolant (car/bike same thing, itís
Blue in color) you donít mix more water in it. Water wetter is for track because coolant is not allowed (hard to clean if spills during crash, it doesnít help in your case, itís worse then coolant as a lubricant anyways)
Check the service manual to when the two fans are suppose to come on, for 2012 they come on around those temps so it may very well be normal. I have seen my secondary fan come on at around 105C
Are you able to do complete flush? Put distilled water, start bike and bring to temp so thermostat opens, shut off, let it cool down, open drain bolt, close and put more coolant in, start again and wait for thermostat to open and keep repeating the cycle keep until clear liquid starts to come out. If you are able to do that and see
Clear liquid coming from drain bolt (you have done the complete flush) then I donít think itís clogging issue.
Make sure when you fill, keep cap open and start and rev the engine a bit just 3-4 times and shut off, fill if level goes down then put cap on and make sure reservoir is full.
All the flush steps are documented in the service manual.
Besides that I would check the thermostat if I were you to make sure itís opening up at the right temp as it should as stated in the service manual.
