I've rebuilt my carbs like 3 times and doesnt turn on as easy as yours but I also have battery issues. Anyways this video is by far the best video on carbs I've seen. Tip my hat to your SIR!

My CB 100 has a bent exhaust valve and a cracked guide, do you have a source fo parts? These are some of the easiest engines to work on.

This video was amazing. So helpful and good music taste

Fuel line is here this other thing is here

Have watched all the cb videos! Great information! One question, is their only one o ring seal between the cylinder and head? Or one on every dowel? Thanks!!!

This video was great to watch, as I get ready to do the same. Thanks for making and sharing it.

I just put a new Chinese fairing on my 1993 Honda F2 motorcycle. The job was labor intensive and took a lot of hours to complete. The paint job on the different plastic pieces was excellent. Most of the holes needed to be filed out and enlarged. Some were off in location by as much as 3/16 of an inch. I started to use a small soldering iron to enlarge the holes by melting the plastic, this was much quicker than filing out the holes. This fairing was injection molded, it's supposed to be better than compression molding but it was still a big hassle to install. The stock Honda fairing would fit like a glove on the bike. It's to expensive to buy a new bike nowadays so I just tried to fix this one up to make it look better.

If that's the way the air filter was fitted it was upside down...

He mentions using dishwashing liquid on the manifolds to get them to slide on. My Dyno jet kit recommended using WD40 instead. Dishwashing liquid will leave residue on the manifolds. They are selling the carburetor slide with the rubber diaphragm assembly for the F2 on ebay at a reasonable price at the moment, I bought two. When putting the carbs back together I used cut up pieces of electricians tape to secure the black rubber diaphragm to the top of the carbs and used a small amount of Seal All automotive sealant as cement before removing the tape. The center hole in the plastic slide that secures the needle needed to be reamed out a little bit with a round jewelers file bought at Harbor Freight, the center hole was just a fraction of a millimeter off which prevented the slide from moving up and down. If that little loop on the diaphragm is a bit out of alignment I think you can heat the assembly up with a heater and yank the rubber in the direction you want the loop to move. They were selling black rubber diaphragms with no plastic slide for a very long time on Ebay. To attach those I think you need a credit card and some dental floss wrapped around the very top of the slide to try and wedge the rubber diaphragm into the very narrow gap on the plastic slide. I tried to glue mine on which was probably a bad idea.

iv learned to mark each hose with a different color market and connector. it has worked very well. Also mark the location it goes to of course.

Is it the same steps for the 1987 600f?

Thank you, excellent video!

Very good video!! Just got my first bike honda cbr 600, doesnt run.... Before i have only worked on outboard and moped carburetors so a little scared to open it up😬 little less now thanks to this video!! Greetings from Finland!!

hey, i am hoping you see this soon. i just finished watching your video on the cbr600 F2 carbs and i was wondering if you could show us how to change the valve shims for it. i also have a problem with my F2 spitting flames. it sounds and acts like a tuned fuel injected bike by spitting large blue flames. it has some very noticeable valve tap at idle cold and operating temperature. I dont know if it’s the valves or carbs but i think ima redo both. i was wondering if you had any suggestions on how to fix this issue. i mean i truly love the large flames and the aggressive sound but it worries me a little much.

the reason the screws are stripped is because they are JIS screws (japanese industrial standard) different than phillips. They are identified by the dot on the top of the screw.

Just came into a 71 CB100. Pretty excited. Its super clean. I do vapor blasting and build bikes. Would be curious as to where you are with your build.

I want you to know you are the absolute best, there’s absolutely nothing out there for these motorcycles to watch

The rebuild kits work, i just did mine and it runs good! Only thing that was junk was the seals. I didnt use those cause the size was way small for some reason

Did you balance after the rebuild

I have a 1971 Honda cb100 can you repair the engine

I have a question how do I change the diaphragm on the slide I'm having trouble taking it of the slide

Great detailed info.

An amazing guide! Thank you very much!

Is the rubber o ring inside the choke plunger also included in the kit? I've got 2 plungers where the rubber has hardened up and fallen out.

Excellent video, I saw it complete. You are very good at explaining, it helped me a lot. Thank you so much. Greetings from Buenos Aires, Argentina

thank you sir its may 6, 2023 and i just rebuilt my carb for my 93 thank for the videos and thanks jim for the rules!!

This mechanical job turned into a nightmare scenario. Do you have any updates on the status of your work on the motorcycle? I have a 1990 Honda NS50 50cc water cooled street motorcycle. The bike has a couple thousand miles and is in mint condition. Being a Honda motorcycle a collector would probably pay a lot of money for a bike in this condition. These bikes were popular in Japan but not here in the USA. I don't know if you can even obtain parts for the bike. It was sitting in a dusty garage unused for 5 years. I put a new battery in the bike and it started right up! I bought new tires as the original tires have cracked sidewalls from age. Yamaha had a small 50cc street bike in 1990 but the NS50 had more horsepower and could outrun it.

The govoners of cb 100 and xl 125 are the same ?

My idle screw won’t go bacc in the hole please help

Hi just a question for you I have a 2003 Honda hornet 600f a 599 to you lol and my air filter is drenched in petrol do you know what is causing this. Thanks Liam

Thanks I am going to attempt this on my cb600f hornet good video thank you

Hi, could you do a tutorial on how to change the fuel tap on the cbr 600 f2...

Hey if you could help me with my bike please my f2 turns on turns off on back fires wa u think I do have great spark

I'm currently working on a cbr600 hurricane f1 that has sat for a an indefinite amount of time, when I reinstalled the carbs after cleaning them I had trouble reinstalling the cables 😅 , I also noticed o had a leak to but it was due to not setting the carb flush to them silicon couplers 😅😅

Nice video-- I have a '91F2 that I am going to tune up, but I don't have the patience to remove, clean, re-gap and reinstall the plugs as you did!! I'm just going to put a set of NGKs in there & run 'em until the mileage interval is up. Just curious--what is your oil preference for your cycle? Thanks again for the video.

Hi David, really helpful, thanks I was just looking at mine and found your video. Can I ask if you know about the black lining on the edge of the weights. Bits have peeled off on mine. I was wondering if it was insulation and if it will affect the spark/ function of the advancer? Or to reduce friction? Thanks, Dan

Great video, helped me more than you know

The rebuild kit I got the reviews say the gaskets are too big. I'm gonna take a little time to try to shrink them a bit with a heat gun and if that doesn't work I'm just going to use some gasket maker shmoo to make the bowl orings.

Part 2 pls

Just came across you channel, love your videos. Keep up the good work. Subscribed from Scotland

I don’t know what I’m doing wrong but my top throttle cable the cable when I hook it up I can pull it back far enough to get it where I’m supposed to tighten the bolts to have it in place

I bought my Honda F2 sportbike back in 1994. It has the original brake fluid in the lines, it's never been changed. I'd say the bike is due for a brake fluid change. I watched about 3 KZfaq videos on how to do it and went to Ebay to buy some clear bleeder tubing. They have these 8 dollar bleeder kits on Ebay that have the tubing along with a one way metal bleeder valve. The thin diameter of the input tubing would not fit over the bikes bleeder screw so I had to cut a small piece of the fatter tubing that connects to the other end of the bleeder valve and slip it over the end of the thin tubing in order to connect it to the bleeder screw. None of the KZfaq videos I watched were using a one way bleeder valve kit. It really seems like the best way to change the brake fluid is to use these one way bleeder valves. The whole process of changing the brake fluid is much simpler. I just installed a 6 Sigma jet kit for the carburetors on my F2. The jet kit works well on the bike but the extra 2 or 3 horsepower it provides is not really noticible or needed for everyday use. If the carbs are off the bike I have heard it's a good idea to slightly raise the main needle that connects to the vacuum slide by adding an additional washer.

Very good guide thanks, I'm about to strip a US import xl100 which is the same I think

I finally got my F2 up and running. The bike only has about 21,000 miles. I think about buying a new motorcycle but they are all very expensive to purchase, except for those cheap Chinese motorcycles you see advertised on the internet. If you buy a carburetor rebuild kit it's best to stay away from those Chinese made deluxe kits that sell for $10 dollars. Regardless of the description shown these $10 carburetor kits are notorious for having wrong parts added to them. I saw a complete K&L carburetor rebuild kit for $80 dollars on ebay the other day. I would think by spending a little bit more money there would be less likelihood of the parts in your kit being messed up. The use of dish washing liquid for the installation of those rubber manifolds was a good idea. I had good luck getting those rubber manifolds to stay on by tightening the clamps for the no.1 and no. 4 cylinders first before tightening the clamps on the no.2 and no.3 cylinders. I was not sure how to install that lower throttle cable in regards to the position of that one nut. This video did a good job explaining the proper way to install the cable. The throttle would probably still work if the lower cable was installed wrong but it's better to have it hooked up the right way with the nut in the correct position.

Thanks!

To me this is pure gold, thanks! 🙏🏽👍🏼

He says not all the way for the choke cable retaining thingy and I totally lost that piece 😂 still trying to find out the real name

One thing I can say about these current Chinese motorcycles is that they seem very under powered for their displacement. The CB 100 and the CB 125 that I owned had good power delivery and good top speed for such a tiny bike. The Japanese really did a fine job getting a lot of power out of a tiny engine, something I can't say about these low cost Chinese bikes produced now. My 1991 Honda NS50 street bike has a tiny 50cc engine and I used to get it up to 54 mph on a slight downgrade.
