@@2strokeguru my English getting better and I don’t have difficulty to understand you. You are very good in vulgarisation, a very good teacher. I just want to do a tune up now. After 5-6 hours of watching 👍🏼👍🏼
Thank you for the video. My two sensor wires were totally disconnected and was only able to find a place to connect the flat connector. Does anyone happen to have a picture where the round connector should be connected to?
Thanks for the video do you have any tips to get that little piece holding the throttle cable out? I saw you used a dentist tool, I'm having a hard time getting that out
Do you have a follow-up to this video? I have this same issue with my Beg Bear and I think the float pin is not seating correctly?? Do you bend the tab that the float pin is attached to??
Do those two sensors in the carb make a big play in the atv running because I got a carb for mine and it doesn’t have the connectors for the two wires that go to the carb
Thank you so much for your informative video. Just what I needed. Keep up the great work. If you needed to replace the float assembly would you use an OEM kit or do you have any aftermarket recommendations?
Can the 3.0 fit a 400 big bear if so im looking into getting another carb because my needle in my carb has gotten jam some how only thing that makes it go is the throttle cable not getting the power it supposed to get because of the needle not moving wen you press the gas
Too properly release the throttle cable from the carb, you need to move the piece it’s attached to into the accelerator position so as to give it enough slack to get the brass piece out
Hey Kevin keep up the excellent work man. I really enjoy watching and learning from your videos. I have a f11250 that's scavenging oil from crankcase smoking like a train. What's your professional opinion on how to approach the rebuild. Thanks for your recent replies.
@@2strokeguru I took the Exuast tip out this winter it was completely saturated with the oil mix residue I cleaned it repacked it.

I can't get the carburetor out because the throttle slide is stuck and won't go forward so I can't get the cable out. I've tried pushing it with a flat head and hitting the gas doesn't work either. It's a 04 big bear 400 4x4 that's been sitting for a few years. Any tips?
Penatrating oil or remove the cable from the throttle at the handle bars pull it through so you can get the carb out then ultrasonic clean up that will free it up
I got the same carburetor I just replaced with a new one but the sensor was missing , where can I purchase a new one ? I lost the old sensor when I took the old carburetor apart. Do I need the sensor to start the atv?
Hey! I have an 08 big bear 400 with only 150 miles on it. its been sitting for years and i was planning on replacing the carb. I keep seeing these cheap 40 or 60 dollar carbs that say they fit my model yet the OEM part is 250-350 depending on retailer. whats the deal with those cheap carbs would it be worth it just to see if i can get it running?
Odds are it will work. Just expect to go through a few lemons till you get one to work. Unless the the carb is rusted just clean it. Parts very accessible for that model. Ultrasound is your friend. Bur a good carb cleaner a carb kit and forced air also good companions.
@@kansascityshuffle8526 got a rebuild kit, gonna try to fix it up first. got to start up with a little sniff of ether so I think it will go with a clean carb and fresh fluids. etc,
@@collinmc90 ha did this a year ago. Ended up having to take it to a shop. My only sin was that there are two jets in my 09. Apparently they can actually be put in the wrong hole and threaded in.

What are the 2 wires you pulled off? I have an 03 big bear 400 and it wont go over 25mph.

Watched the whole dang thing to see how float was set. I don't care about the other jobs you have scattered about. Removal process was helpful.
Thank you
Is that fuel enrichener air sealed if it breaks will it cause the engine not to run

I just changed my carburetor on my 01 big bear and have it idling perfect but once I give it throttle it dies what is causing this?
I can’t find where to plug the two wires in front of the carb?
I have an odd question but shouldn’t I be able to blow threw the line that hooks to the gas tank? I can’t on mine and it seems like I’m getting no gas
Can the 3.0 fit a 400 big bear if so im looking into getting another carb because my needle in my carb has gotten jam some how only thing that makes it go is the throttle cable not getting the power it supposed to get because of the needle not moving wen you press the gas
My bike is running great but whenever I rev the throttle hangs. It’s a new carb so I don’t see how it could be the jetting.
Too properly release the throttle cable from the carb, you need to move the piece it’s attached to into the accelerator position so as to give it enough slack to get the brass piece out

is it burning engine oil and 2 stroke oil at the same time
Yeah
It's got good compression but the spark plug always has oil on it and it leaks on the left side of the bike over time

iF you unhook the cable at the throttle it will release slack to remove it easily in the carb. Easy to release and rehook up.
