Knowledgeable, very thorough, and calm. It’s easy to let the frustration of working on machines get the best of you yet you allowed yourself to remain calm. No cursing, no slinging tools, just cool and collected;very respectable sir. I enjoyed the video and thank you for sharing. Have a blessed day.
Thank you! Appreciate the comment and thanks for watching! I have a YZ450 2024 I will be digging into today. It was dropped off and I was told it need a new coolant spout and coolant engine temp sensor. The plastic one melted (its very close to the exhaust header and the rider is very very fast) and it lost its coolant. Well just last night I got word the bike also does not run. They didn't tell me that on drop off so now I'm thinking its going to be more than just a coolant senser. The good news is its friday, Hope you have a great weekend!
You’re very thorough, for sure. Love the display of determination. Great video!
Thanks Anthony!
Kudos to you for figuring this out. Electrical issues are no fun to sort out.
Thanks and that surely is the truth. And when you add protection circuits in the mix 😮. Not sure why but it seems that aftermarket stator was causing the protection on the computer to reject the fuel pump too easily. My brother seems to think maybe the voltage or amps was too far off but who knows.
When you mention "noise" in the generator, that is what we call dirty power in the electrical industry. When it comes to sensitive equipment, noise can absolutely wreak havoc. In ac voltage, we use isolated grounding conductors. These grounds go from the devices on the branch circuits all the way back to the furthest grounding electrode in the system. This eliminates, in theory, all of the other "noise" in the system. By noise, I mean things like objectionable voltage or current on the grounding conductors. Tricky issue you have on your hands. Doing that Upallnight magic!
Geez I bet chasing down noise in AC is probably a nightmare lol. On this KX is so strange the computers protection circuit was being overly sensitive and all I did was put the OEM stator back in and that went away. It was a guess and a shot in the dark. But I have seen aftermakrt stators cause funny things to happen so it was worth a try. Hey wanna do 74 sat?
That was a tough one for sure. Good job sticking with it!!! Awesome outcome. Joe.👍
Thanks Joe. That one surely had me chasing my tail lol
Man…. Talk about a gremlin for reals! Thank you for showing us 😮💨😮💨 I would have gave up on the voodoo bike lol
LoL.I felt like throwing in the towel a few times lol
Nice job!
Thanks Mike!
@@UpAllNight91 You're welcome! love watching your videos
@@mikekraz6193 I appreciate it and glad to hear. That was a tough one lol
You should take the 125 out. Just nothing like the 125. Awesome diagnosing skills man. Electrical issues are my nemisis...lol.
Holy cow you surely tempted me too. But I did have it planned to do some jetting changes on the 250 this week. But I almost bailed on that idea and took the 125 thanks to you lol. She sure is fun. I think I will next week.
Another great video!!!
Thank you Sir!
Brilliant video thank you. The front sprocket and chain look very worn. Probably losing some power there.
Thanks and oh yeah, sprocket and chain was shot. The own delivered the bike with new chain and sprockets and I installed them after doing this video. I wanted to get her running first lol. He picked it up yesterday and was excited to have her back!
@@UpAllNight91 Cool. Keep uploading please. Your videos are so helpful and interesting. I thought I would just skip through but I watched the whole thing.
@@jakebennett4307 LoL, thats awesome to hear!
I went through the pain of figuring out how NOT to use dielectric grease. Exact same as what you dealt with on that bike except mine was the coil connectors on my vmax. Thought I did a good thing sealing out moisture, but I also put it on the inside of the connector where the wires intersect. The vmax started running on just 3 cylinders out of the blue and long after I applied the dielectric grease. I narrowed it down to coil #3. So, I pushed on the coil connector and the cylinder started firing again. Took me about another 30 minutes to figure out it was the dielectric grease. Then I commenced to cleaning the other coil connectors and removed all traces of the grease. Never had another issue since.
Oh man yeah. Surely it can cause connection issues. The only place I have found dielectric grease works good for me is spark plug boots, to help keep the moisture out and the spark in. And thats only when its needed, otherwise I dont use it much.
Walbro 400-766 , is the fuel pump kit i was talking about, not sure itll work actually. i thought they had a more similar rubber foot adapter . might be able to cut it, but for the price and effort , better off just going OEM . i knew it wasn't exact , but thought it would be a easy local accessible part . i tried.
Yes sir. Thanks. The owner of this KX runs a Oreillys, I was surprised to hear he orders pro X air filters and stuff like that right from his store lol
Yes great looking for the fault!
Thanks! That surely was tougher one
Hi Chris ! Where can we find the right connectors male and female and the terminals for our bikes ? It's not available on OEM so how do you takes the good ones ? Thanks a lot for your work. Greetings from France !
Hello. Yes OEM does not sell them. Not sure if someone sells them aftermarket, would be nice if someone reading this knows if there is someone selling these aftermarket. But what I do is collect old wiring harnesses. When I replace a harness for someone I ask to keep the old one. And I use them for the connectors when its needed.
@@UpAllNight91 Thank you man 😊
@@juju-of2by Yes Sir! 👍
Have you done any work on the air cooled YZ’s?
who hasnt?
Only thing I rember about the old air cooled bikes is how much power they loose when they get hot. Glad your trying to keep one alive
@@tndeereI restore the old Yamaha Enduros and race bikes, I have two 75 250 Mx’s and two mid 80’s YZ 250’s.
I never really noticed any loss of power.
@@donbridgewater2988 Thats great i'm 58 years old and a life long trail rider.The last 2 air cooled bikes i had were a 1978 PE175 1999 Honda XR250. Wish i had never sold the XR think it was the best bike i ever owned.Was like a tractor in the woods.I road it for over 10 years.
@@tndeere I'm 48 now and havent had too many air cooled bikes come through my hands for repairs except for little play bikes and such. But I did own a 1978 PE175 for like a week. I bought it because the owner somehow got it street legal with a tag and all. But after riding it around for a few days I consistently had cops trying to get behind me to check me out lol.
try MAP sensor brow
Hello. Chased it down to the stator.
hi, need help. new fuel pump, brand new. where is the problem? works for about 4s and goes out.
What make and model? Also what happen that it needed a new pump (was it sitting too long)?
Hi
