OH YEAH ITS A 07 450ER

[440ex. ehhh!!]

Do you always have the fan running??

If so, you might not be running it hard enough and that coolent is getting too cold and making the motor not run hot enough. I am not completely sure on this as i just got my 05 450r about a month ago, and i did the same thing, except i wired my fan in to a switch so i can turn it on and off whenever i want. I noticed that if i am not running hard enough and the fan is on, it WILL make it run a bit crappy like it was just started after sitting for a week.

Hope you understand what I'm saying.

i totally get u, today while i was looking at it i did exactly what u did by wiring to a switch. figured it was the only thing i changed. unfortunatley i couldnt ride today but will tomorrow, ill post whether it worked or not.. thank you for ur time to answer me

how do you wire it??

[smokinone951]

first i used a single pull single throw switch, basic two terminal switch, ran one terminal to sensor wire( spliced into it not cutting it) then ran other terminal to ground. basically it allows sensor to run normally, but if i choose to i can hit switch and give current a path to ground. when i rode today it ran great started good idle really good, ran excellent. rode for bout 20 mins( jus a quik ride, when i got home i stopped and no problem , but when i went to rev it it died. im at a total loss..........
