Bike overheating & dying
I've scoured the internetz for answers on this and basically took my bike apart top to bottom. Not sure what the issue is yet but would def appreciate your thoughts on this issue.
Details: '09 KLR650, recently acquired used (was fine during purchasing, only recently started acting up). Recently, when out riding on city streets, idling at stoplights, etc., my bike temp gauge will start to rapidly move towards the red zone and eventually cut out completely. Like, I can visibly see it moving upwards which makes me die a little inside, lol. I can restart it again while rolling and giving it some choke and gas but it keeps up with the dying every few minutes. It dies while stopped, while moving, doesn't seem to matter. Fan kicks on fine.
So far, I've:
Replaced air filter, oil filter, oil change, topped off coolant in radiator and in overflow, cleaned and rebuilt carb, seafoam in gas tank, new radiator fan and fuse (fan wasn't turning on, I think the motor was bad), new spark plug.
I've ordered a new thermostat water temp sensor, new thermostat, and new radiator fan switch (I think the old one is fine though since the fan turns on, replacing it anyway cuz new parts!) and will replace all those this week. I've burped the radiator and the coolant circles fine.
Tomorrow I'm going to take the cover off the water pump and see if it's moving properly. Does anyone have any other ideas on what to tackle next if the new sensors and thermostat don't fix the overheating and dying issue? TIA! And sorry if this is repetitive. I searched through most of the hundreds of threads here related to overheating and nobody seemed to have the dying issue like I'm having.
