i read through tons of old posts for hours but really never found a "final answer"... mine and my roomates 05 636's are overheating within 20 mins of riding....did anybody ever figure out what's up with these things and how to fix??

any help would be greatly appreciated..

dan jackson fixed it.

and i do believe it was bill d that showed dan how to fix it with a radiator cap that has 1.3 on the pressure rating not 1.1 and it does work well.

sssshhhh keep this under the lid.

!!A2K!!

hook ur fan up to run as soon as ur bike turns on.....or gut the thermostat...and i heard that diff cap works alright..

could be a malfuctioning thermostat. my friends 05 636 used to spit coolant even with the fan hard wired.. if all else fails get a new radiator.

mine used to overheat a lot. turned out to be the radiator neck that was slightly tweaked so the cap didn't seal properly, wouldn't hold pressure, etc......new(used) radiator fixed it

i know this sounda REALLY dumb, but check your coolant.
my 636 was overheating and getting really hot, i didnt think to check the coolant since the weekend before i just flushed and replaced the coolant with engine ice.
luckily i fixed the problem right away, but it turned out that i got a small knick/cut in my line and lost almost all my fluid on the way to the lot. and i never saw a wet spot or noticed it until the temp got really high.
i checked everthing else first other than the coolant
then finally checked the coolant........ fixed the leak, refilled, now i run around average 208-212 in the lot at a high idle, which is pretty low.
MORAL OF THE STORY......CHECK THE EASIEST MOST OBVIOUS STUFF FIRST.
