took it for a ride last night after i removed the thermostat cause i thought it was running a little hot at 223 on local streets any way now even when im on the highway its constantly going to 221-223 and the fans keep coming on to keep it cool and i feel alot of heat coming from the exhuast specialy my left foot any ideas? its an 05 r1 by the way.

 

yamaha's run hot but on the highway??? thats not good

 

i know that why im kinda worried i might have a blown head gasket

 

and other than the temp what factors makes you think you blew a head?

 

just the temp it still runs fine besides that

 

are you suposed to bleed the coolant system on this bike like a car ?

 

i never heard of that but worth a try.


does your oil look like milk kindof?

 

nope ive never heard of bleeding the coolant on a bike but it has the same symptoms as a car

 

i wouldve already tried it

 

i didnt see a nipple to bleed it out of

 

are you burning the colant out of it?

 

not that i can see every time i check the rad its full

 

your prob fine, these bike run hott

I had a 99 and it would get super hot, if i would wear shorts i would burn my knees on the frame it would get soo hot

if you had a blown head gasket you would know it

 

if you blow a head gasket you would be blowing white smoke out the exhaust lots of it, also your oil would look like one of your buddies nutted in it. my friend had the same problem on his 07 R1 he got an exhaust for his bike not to try to fix the problem but just cause he wanted it but it did run about 20* cooler, but the real problem turned out to be he had air in his cooling system.

 

how do you bleed the air out of the system is there a nipple somewhere?

 

im not sure if its the same on a bike as it is on a car but whenever change a radiator, coolant line or am just doing coolant flush i use a machine to suck all the old coolant out and shoot new coolant in and usually no air is in the system afterward but when there is i let the car run with the radiator cap off(the air will escapre from there) till it reaches opperating temp and let it keep running for about 5 mins, as im letting it run im under the car with a rubber mallet tapping the bottom of the radiator so the air gets out of the system quicker. after the 5 minutes it should be good and if not i take repeat.

 

just take it to a shop though and tell them the problem, and that you want them to flush and fill your cooling system and theyll do it for you with the machine, or have them look at it for ya. but if you fan is kicking on than at least your t-stat is working, now wether its kickin on to late i dont know but at least its kicking on.

 

well there is no t stat cause i yanked it out thinking it would solve my problem

 

you yanked it out? as in you didnt put it back in? hmmmm put it back in, the t-stat is what controls your coolant flow takin it out will just make your problem worse.

 

ill put it back in and see what happens
