This is a GREAT video. Seems to be a very common problem. Recommended a must watch to everyone I know. Keep up the great work, it ain't easy doing the YT vids but you'll be rewarded with subs.
@@lowerclass4182 you know what thanks for that! The oil is milky and I was thinking head gasket or waterpump, I'm thinking more head gasket. It's an 08kx 250f
Figured I’d just come to here I’m a little stuck on the bike, I got an 08kx250f bored out 290cc Athena, she’s also got a full fmf 4.1 cherry bomb on it. My cousin (previous owner, not in good contact) used to ride it all the time with the same components, same jets, same exhaust and bore, I cleaned out all jets so I could see through them, I cleaned the bowl, floats, etc. and she still bogs down without the choke, and backfires when I take the choke off and feed gas, without gas it shuts off. My bike also still runs while the fuel screw is all the way in, I’ve tried adjusting it between the 2-3 turns but no difference
My vm26 mikuni carb starts on half choke once it's running I take choke off it's dies, fuel mixture is turned out 2 and half and also the idle screw. Pilot jet is a 20 will I need to install a bigger pilot jet like 22.5? I have a yx140 engine
I cleaned my pilot jet and I could see through the hole. My crf150r still won’t start and idle with the choke off. Anymore tips you have that might help?
Hey man idk if your going to see this but I got a apollo 125cc I’ve look for so many videos on how they can help and really I’ve been so stressed out I’n life but the bike starts on choke up but when I put it down it turns off or sometimes it stays on with choke Down but when I rev it it dies and also when I ride it with the choke down it sounds like popping noises like popcorn I thought it was a misfire so I thighten the muffler also keep in mind I thought it was the carb so I bought a new one put the new one on and still having the same problem help?
I'm sort of knew to dirt bikes, rode mine for a while but don't know how to work on them. My 2018 crf 150rb wont start without the choke on and just a touch of throttle even on really hot days. If I don't use the choke its really hard to start and dies the second you try to even budge on the throttle. It runs great when it gets warm, bogs a little until its hot. But is it normal for me to have to run it with choke on even in warm weather, bc if I don't it wont start?
When my rm250 is on choke it idle when I turn it off it dies out. I can hold the throttle open a little when the choke is off and hold jt at idle rpms and its fine. Can I just adjust my idle?
Thanks man this is what’s been happening to my 06 RMZ250 , it only runs when the choke is on and once you turn the choke off , it bogs out and my bike also leaks gas when i kick it over and idea on that ?
I just brought a 05 rmz250 yesterday the guy said it’s been sitting for a while but I start it and rode with the choke up soon as I put it down it dies.. and suggestions
Yeah, did all that a million times, does not fix the problem. Want some other answer that says its something other than the idle jet being clogged, because it's not. I can fill the idle jet well with solvent and it will siv right through it. Rebuilt this thing with new parts 50 different times, putting it on and off again, with the same problem. Only runs on choke, and stumbles when you twist throttle. It's not the idle jet, pilot jet, or master jet. I replaced that whole jet with one with clean holes., and made sure fluid goes through all 3 jets.
Just like landen p mine is doing the same. I blew it apart cleaned it air hosed out. I know it's clean and clear, see day light. Anyone have a idea on what it is. All new 125cc chinese 4 stroke
Hell yea man been subbed scince last year you just fixed my bike thx 😊
That’s awesome!!!!
I love this dude videos he is so chill and great content..keep it up %
Thank you!

Thank we we have been working hard to get new content out a lot of good content on its way
if you cant see through the pilot jet its because its still blocked lol - use some wire or a thin baby bottle brush to clean it out properly!
Not entirely true. I have a bran new carburetor and won't Idle unless the joke is turned on
Just rebuilt my carb cause the bike ran like junk and still only runs on choke
@@danthisguy8541does it have a radiator ? If so check for bubbles prob a head gasket blown
@@lowerclass4182 you know what thanks for that! The oil is milky and I was thinking head gasket or waterpump, I'm thinking more head gasket. It's an 08kx 250f
Same here......brand new carb

im having the same problem with a yzf 250 rn
If there is bubbles in the radiator you need an new head gasket

Pilot jet is a 20 will I need to install a bigger pilot jet like 22.5?
I have a yx140 engine
Yes sounds like you are not getting enough fuel at low rpm
@@throttlefamily4655 okay I will swap out the pilot jet, I will double heck my float height also
@@high_lyfe8546 sounds like a good plan you will get it figured out and it will run great soon
But my motorcycle is brand new and I have this problem? I have only driven 20 km with it what can I do ? Beta rr 50 2022 motorcycle
I cleaned my pilot jet and I could see through the hole. My crf150r still won’t start and idle with the choke off. Anymore tips you have that might help?
does it spit flames and pop without the choke on
@@onlysnaps420 it pops but doesn’t spit flames
@@codybui1907 i adjusted the valves nd she not shootin flames no more lmao
My yz 250f runs finds with choke on but when chokes off it dies or if I give it gas it’s backfires like crazy? Can you guys help me
It could be a few reasons but the number 1 problem I’ve come across is valves may need to be shimmed

Did you get it fixed? I have the same problem
were do i find an aftermarket fuel mixture screw cause the one i have rn is so hard to get to
Mine runs fine without choke if I try to start it with choke it will not start can someone help

No your not supposed to run the bike with choke on. The choke is only to cold start bike. Running the bike with choke on causes engine problems.
yes this is a normal thing the choke is helping it gas to the carb temp does not matter
When my rm250 is on choke it idle when I turn it off it dies out. I can hold the throttle open a little when the choke is off and hold jt at idle rpms and its fine. Can I just adjust my idle?
Possibly but I would say you need to clean out the pilot jet
@@throttlefamily4655 what if you installed a completely new Carburator.
And when the bike it's with injection and did the same thing , what is the problem?
Thanks man this is what’s been happening to my 06 RMZ250 , it only runs when the choke is on and once you turn the choke off , it bogs out and my bike also leaks gas when i kick it over and idea on that ?
Check carb drain plug or feul line

Check your engine compression and also check that your valve are adjusted correctly sounds like your issue could be with the motor itself
my pilot is 35, can i go bigger?
Cleaned my carberutor and bike still won't idle without choke
You may need to adjust your valves
@@throttlefamily4655 i adjusted my valves, and cleaned jets and still won’t run without choke on, is it possible it needs new valves?
@@brandongrkman593 head gasket?
New engine? @@brandongrkman593
The choke acts like that carb on my 125 brand new carb any help
Sometimes from the factory carburetors have metal shavings in the pilot jet try taking it apart and cleaning it.
did you get it fixed landen?
@@silentlyfe3660 nope gave it to my mechanicly inclined friend

@@antoniogonzales9065 could just be your idle bro screw your idle screw all the way to the right then do 1 full turn to the left then try it
