Best video on the subject. This guy breaks it down in the clearest, step by step, real world application. Watch all 4 videos, and if you don't totally understand this carburetor. Then you should go sit down and not work on motorcycles. Sorry, but it's true. This guy explains everything absolutely perfectly.. Great job
@@souperdoo , I went with the KLX mod. I have an after market exhaust (2 Brothers) and UNI air filter (and pulled the snorkel from the airbox). Eagle Mike says 42 pilot jet and 142 main jet. I put in the 142 main... but the 42 pilot jet is blocked so I'm using a 45 that I have on hand. Can you foresee any issues with the 45 pilot jet being part of the mix? Thanks!
@@searchingfor6thgear44 , Nah, probably not. You'll be a bit rich on the first half of the throttle is all. That's better than too lean. The worst case I can see is that you might have a bit of a stumble from it being too rich. When you can you ought to replace the 45 with a good 42, though, but no reason not to ride it. Tom
I like everyone who has commented on all 4 of these video, I loved them. I learned a lot and felt 100% capable of rebuilding my carburetor in two sessions. One night of taking it apart and the next day reassembly. I did soak mine in Pinesol and it works great. I would love for you to do a tuning video as most of them make no sense. Thank you and keep up the great work and videos. Have a great and blessed day brother...
I've relied on this video series once again! I've dove into my carb or my son's KLR carb four times in the past year. Each and every time, I refer to this series on how to take it apart, clean it and reassemble. You have presented us with an exceptional resource. Thank you!
Tom, it’s fine. I don’t have to use the choke to start! Pulling the carb out, around the crash bars makes tinkering a pain. I’d like to swap in a 42, but will wait for winter maintenance season.
I've watched these videos three times now; once for each time I've left my KLR sitting for too long without riding. Thank you so much for taking the time to make these!!
Hi John, I am glad that they have helped you out, but I think you'd be better off just riding the dang thing so the carb doesn't get gunked up! ;^) Stay safe out there, Tom
This is very well done; am redoing the carb after my garage guy installed a new slide; the bike hasn't started properly since then, although it runs reasonably well. Many thanks
+souperdoo I watched the video and took the carb apart once again. I put the dang needle on top of the needle holder! I don't know what I was thinking. I still get a little pop on the deceleration. I have 1993 KLX 650 C I did the 22 cent mod with one washer. The bike is stock do you think I should try to bump up the main jet? I haven't even run it yet. It has been sitting dormant since 2007. Thank you I really do enjoy your videos and I subbed you. Aloha, jusride7
+jusride7 A little pop on deceleration is fairly normal and doesn't hurt anything. If you really want to chase after it, you would need to go up one size on the pilot jet, not the main jet. I would leave it be unless it is severe. Tom
+jusride7 The stock pilot jet should be sufficient unless you've done something significant to either the intake or the exhaust. Any changes to those? Have you tried adjusting the idle mixture until you get the highest idle, then backing it off a half turn?
Thank you Souperdoo for this and your other KLR videos. Carb rebuild was souper simple with your video! Souperdoo, Eagle Mike and Tim2Wheels may be the KLR Holy Trinity!
Hi, Thanks for the kind words and I'm happy that the videos were of use to you. Have a look over at the blog site where you don't have to listen to me talk ;^). www.souperdoo.com Tom
That was a great series of videos for the carb. I have been having trouble with the choke intermittently malfunctioning and battling to start. Otherwise it runs perfectly, good consumption and idling. Is there anything special one needs to do with those starter jets and air vents in terms of cleaning? Must the whole carb. be disassembled. Thanks for any advice.
Mal - It doesn't need to come apart. Just drop the bowl and remove the brass bits. Soak them for a day or so in a bit of PineSol to loosen any deposits. Ream the holes out with some fishing line and/or a strand of copper wire. Tom
@@souperdoo ou have an email address to send you a picture of my carburetor cvk40 of my klr 650 2013. Where I think that the screw that regulates the air-fuel mixture has a lid. and I have the doubt if there really is the screw that regulates the mixture and if so, how to remove the lid to access the mixing regulator screw
@@rajafari , Yes, there is a lid over the screw. It is to prevent you from turning the screw to satisfy the EPA people. It is easy to remove. Simply drill a small hole in it (drill slowly and be careful not to punch through to the screw underneath the lid) and then insert a sheet metal screw into the lid and pry the lid out. See this video th-cam.com/video/Sb3WJjmVK4Y/w-d-xo.html at 2:30. My email address is contact@souperdoo.com if you have any issues. Tom
@@souperdoo thanks for your help. First time in my life that I do maintenance on a carburetor. I did it because I saw your videos and I was encouraged to do so. My bike hard unused and without lighting 3 years.
Hi,,,watched this with great interest,,,my other half has a Honda CB400 super four, she doesn't ride it much so it's got one poorly cylinder on it,,,,going to have to clean the carbs,,,wasn't familiar with carb stripdown so I've learned a great deal from you,,,very informative,,,I don't think it'll vary too much from this carb shown, but i've got the jist of it now on what to do ( and not to!!) ....Will let you know if I succeed ! Regrds,Paul,
spudgapix Paul, A CB400 Four! Cool. My first real bike was a CB350 and I always lusted after a 350 Four or a 550 Four. Good luck with the carb rebuild. Tom
Awesome video set! Can't wait to start. Unfortunately my CVK40 took a 5 foot fall into a wooden surface. Do you think any parts would be damaged at all?
Anything that could be damaged in a fall would be on the outside. The fuel and vent elbows could be broken or cracked. The throttle plate/shaft could have been bent. The intake or outlet could have been dented. If there's no evidence of any of that, I'd bet you're A-OK. Tom
That's a drag. I just came across your safety wire tip for the drain plug...Thanks. Definitely going to try it. I didn't look at the torque setting last time and turned the bolt 2 full rotations after finger tight :O
Hello my friend!! Great videos, congrats and many thanks. Could you help me in one short question? I have a 1994 Klr 650 and something is wrong in the carb. When I perform a cold start with absolutely closed choke , the engine starts but i need to open the throttle to keep the engine idling. There is a lot of gasoline flowing from the vent and drops to the floor. I think there is something wrong with the bowl. What do you think? Can I fix it without removing the carb? Thanks a lot in advance for your coopertation. Regards!
very well done video, very usefull, there are no that many information for this bikes, thank a lot for your help. keep going very profecional even a child could unterstand, thank you.
What do you use to clean the slide assembly and the multi-pronged plastic thingy that goes into the slide? I'm guessing you don't want to spray or soak them with carb cleaner.

Absolutely the videos I was looking for.
I'm glad you found them and hope they are what you need!

@@souperdoo exactly what I needed just the right info. She runs smoother and more responsive than it ever has since I've had it.
This is the absolute best carb series on TH-cam. I can work on my carb with confidence, knowing this series is available, when I need it. Thank you!

No, you don't want that! I use a tooth brush and a bit of PineSol to scrub anything that doesn't get soaked. Follow up with a warm water rinse.
Still the best!
