Coolant issues
I'm sure the topic has been beat to death, but I haven't found anything quite like the issue I'm having.
8 months ago I wrecked my bike and took the next few months rebuilding. Mostly cosmetic fixes, and nothing mechanically. Or at least I thought.
Since the wreck, my bike hasn't been staying very cool while riding. It rarely drops below 200F and will reach HI just idling at a stop light for even just a few minutes. The coolant levels are fine. I haven't tried burping the lines yet. I had the first service done in October (I bought a 2013 model with 444 miles on the odo). The bike just doesn't seem to be staying very cool. I can't hear the fan turning on so that may be the issue as well. But even at cruising speeds, it doesn't dip below 200F. Isn't 180F about normal for a 75F temp day?
Don't know what to do from here.

200F is normal at low speed and idle, when you get going then 180-190 should be normal.
How did you bleed the system? I am sure you used the bleeding bolt next to water pump?

Just took a few minutes to look around and what not, see if I could find anything wrong. The fan is pushed into the radiator. When I wrecked, it must have pushed the radiator back and the fan isn't able to spin because of that reason. What can I do to fix that?200F is normal at low speed and idle, when you get going then 180-190 should be normal.

Interesting. I don't run any coolent in my CBR, and it runs fine. Sure if I let it sit at idle it will jump to 250, but cruising even on hot 90+ days it is between 168 and 175.I'm sure the topic has been beat to death, but I haven't found anything quite like the issue I'm having.

well, the fan should have a distance from the radiator in order to pull air ,and if there is any damage to radiator then that need to be fixed too.Just took a few minutes to look around and what not, see if I could find anything wrong.

You don't run coolant? No water, no wetter, no nothing?Interesting. I don't run any coolent in my CBR, and it runs fine. Sure if I let it sit at idle it will jump to 250, but cruising even on hot 90+ days it is between 168 and 175.

Seems like the old girl would get hot plenty fast running bone dry...:dontknow:You don't run coolant? No water, no wetter, no nothing?

YES! Bone dry for YEARS! Does it run temp wise like it did when it had coolent? Yes and no - only when sitting does it get hot, so long as I'm moving it is fine (above 15 to 20 mph).Seems like the old girl would get hot plenty fast running bone dry...:dontknow:
I am assuming an animal chewed through the reservoir while the bike was getting serviced at the dealer. When I finally noticed the issue (about 6 months later from when I first noticed a difference in temperature management), I saw that the reservoir had a big hole at the top of it, and inside was a tiny amount of coolant combined with a some dirty rain water. I've since replaced the reservoir, but the same dealer never filled it up when repairing other issues as I requested.
To this day it is completely empty.
My CBR has been a beast of a bike, put through all kinds of hell and back. I hope my Kawi can perform equally as well over the years.
I can't resist the urge. Because your reservoir doesn't have water doesn't mean your engine doesn't. It is only a reservoir for coolant being pushed out of the hot motor and allowing it to return when cool. Surely there is at least some water in the cylinders or it would melt the pistons. Air cooled cylinders and heads have direct contact with air through heat sink fins that cool the cylinder wall and combustion chamber. A water cooled engine with its water jackets empty has no way to cool the cylinder wall or the head. It would detonate like crazy just before the piston crown started drooling down the cylinder wall.Interesting. I don't run any coolent in my CBR, and it runs fine. Sure if I let it sit at idle it will jump to 250, but cruising even on hot 90+ days it is between 168 and 175.
My apologies dood, I just realized you were only talking about the reservoir and not the engine.
