Nice work Kyle. Very informative! We have 4 KFX450r's. (2 XC Race bikes & 2 practice bikes). We do this procedure twice a year. Enjoyed your coil video as well!
Any idea what the part is at 13:26. I’m referring to the sensor looking part that has a black rubber boot covering it. I lost the black rubber boot and am wondering if this will work if I reinstall fuel pump with out rubber boot?
So my kfx450 will run perfect, but when it gets warm it starts sputtering and no power, if i let it sit for a bit it’ll start and run fine, then maybe a few minutes later it does the same thing. I changed the coil, no diff, i did change my fuel pump a while back, got the pump from ebay, could it be a pump issue since I installed the new one? The fan turns on, no fi lights stay on.

Hard to tell what your talking about but if it's what I think you are talking about it would be the fuel level sensor. I wouldn't think that would effect whether or not the quad runs. It would just not let your fuel light light up when low on gas.
@kyleholtmeyer7292 thanks, the positive 12 comes in on that pin it's the red wire at the plug, I got 12 volts at the pin that feeds that silver part and nothing out. If I put the 12 volts on the other side the pump comes on, I just don't understand, if that's all that is I can jump it out and be fine with it
@kyleholtmeyer7292 sorry I can't figure out how to screen shot your video, watching it the part comes in to view at 13.22 in the video. I have 12 volts at the bottom of this piece, nothing comes out, if I put 12 volts on the top of that part the pump runs
Just did mine and now it won’t start? Before I changed the pump it bogged if given more than half throttle figured new pump/filter and now won’t start? Any ideas?
@@claytonberry5932 no it’s was the throttle cable .. I backed it off and it would started.. might wanna mess around with it.. I clean injectors and everything before I found out that’s what it was… good luck brother 👍🏻
Good video.Helped me get in there to see that the previous owner wasn't running a filter on it.

Great job!!

I hate to be the one to break the news, but it’s the piston rings . You need to rebuild
I’m having the same issue I just did a compression test and it’s reading 60psi when the owners manual says it should be 80

What is the function of the silver part with the black rubber cover. My pump won't run if it's in the circuit

@kyleholtmeyer7292 I also have bought a new pump assembly and it has the same problem, I'm at a loss
Can you screen shot the video and point to the part you are talking about?

Jared Mercer tps?
Joseph Freeman actually it was the throttle cable... I adjusted it all the way back in and it fired right up.. took acouple days to figure it out
Did the filter solve your bog problem mine is doing same thing half to full throttle bogs. I've ordered new pump and filter hope that fixes it

@@claytonberry5932 just adjust the throttle all the way in and see what happens 🤷🏻♂️
Thanks!! Make more videos like this :)
