Overheating... Help/Suggestions, Please!
Bike:2006 GSX-R 750
I recently had a lowside and took the bike over to a friend's place to have the parts replaced as well as getting some parts anodized and powder coated.
He was supposed to put coolant in it, but forgot to and I managed to put some in before I rode/started the bike.
Was planning on taking it to work this morning, a few minutes later at a stop light I noticed there is coolant on the ground and on the side of the bike, temp got up to 235ish...
I looked and I must not have tied the rad cap tight enough, it was just sitting there...
Got to a gas station, tied the rad cap, put gas and headed back to my place. At this point it was up to 235-240*, it reached 248 and that's when the warning light started flashing, I shut off the bike and coasted for a while before I started it again...
While it overheated, it didn't go over by much, reached max of 251* before I shut it off and coast again.
I was literally 1.5 miles from my house before I turned back.
As soon as I got home, I put coolant in it and let it idle, the fan kicks in when it's supposed to (220*) but the temp is still climbing.
I looked on the ground and saw a lot of coolant on the ground.
I took the fairings off to look for leaks and I didn't see anything dripping.
I attempted to top up the coolant but it wouldn't take any more. it was full.
When I did add the coolant the first time, I filled up the top and ran the bike for a minute or so with the cap off.
Topped it up some more and called it a wrap.
I'm guessing it's either air in the system or a thermostat issue.
I did have the water pump cover powder coated, but I don't know if he changed the gasket or not.
There is no way I damaged the engine/head gasket etc. but I'm a little worried.
There are no signs of a blown head gasket, coolant is not mixing with the oil and no antifreeze smell coming from the exhaust.
It's cold here so there was some steam coming from the exhaust, but it didn't smell suspicious at all.
Any help on what I should look for would be appreciated.
