- In this episode, I have a ball cleaning out the carbs on my bike.
Important Note: Don’t forget to clean the idle jets like I did! Jdamage68 pointed that out to me in the comments. It’s very important to clean those, so be better than me.

Great video. There are not a lot of videos of this kind for the ZR7s. Got my like.
In love with this series, I LOVE my 2003 zr7s, perfect speed for me. This series has helped with some repairs already and I love seeing how much your channel has grown!
20 years later and these bikes are still running
How many miles does your have? Fixing one up right now amd try8ng to ballaprk their longevity
@@kmachakaire my bike is 24 years old and i love it
7:20 its very easy if u warm them up a little bit with a hairdryer or smth like that then they will easily fit in the hole. if the rubber is too cold it gets stiff.
Wow that is so helpful! I'm more than likely going to have to clean out the carbs again at some point, and I will definitely remember this! Thank you so much!
Main jet holders and jet needles are DIFFERENT for 1/4 and 2,3 cylinders. You possibly switched jet holders
New Rubber gaskets?whered did you get it
As a man with large hands I never want to have to work with those boots again... Seriously a PITA to reinstall the airbox boots FS!
Todtiger you would be surprised at what you can do when you make your mind up to do it. There's plenty of help out here in virtual space just look at all the videos you can stand, and pick and chose the parts that you feel comfortable with.
cheers
Great video.
Greetings from german zr7s-biker.
do you have one on replacing starter clutch for the zr7
I’ve got all the boots off and the carb is moving freely but did you undo the throttle cable to get it to move completely to the side ?
I did not! You most definitely can do that, but you don’t have to. You should be able to just wiggle everything out with a little bit of finagling. The cables are actually what’s holding the carbs up when it’s on the side
Omg you are so patient
My carb boot partitialy cam off tried putting on and all four came loose.
Straight to kawasaki
Am I old impatient or useless.
Like all your videos
Got same bike...bought it a few months ago. It had torn rubber manifolds on both sides of the carbs. Had them replaced and the carbs cleaned. New feul lines mounted and all hassle was gone. 😊
To bad it coast a lot.😢
How's your bike going just blight one I'm fixing up with some new rings and stuff. What miles is yours at?
@@nathanholm7584 My bike runs fine but at the moment its Parked in the garage for winter. Its now like 1deg. Celcius so just above freezing temp. in The Netherlands.
Is it a Keihin carb?
Yes! If I recall correctly...
dude...if i had talent like you..i would have opened a UA-cam channel
Sounds like some home made music almost fell asleep but Thank You for the vid. L.A.
It's by the artist Artificial Music on soundcloud! Very calming yes haha. But you're welcome!
Awesome video. I'm in the middle of the reassembling but these boots ... how can I put them back to positions? I spent an hour without success. I hate this construction.
There really is no good way! It helped a lot that I have long and thin fingers, but it’s really just a matter of squeezing them on carefully after pushing them through the inside of the box. Someone told me that it also helps if you use a hair dryer or heat gun to warm up the boots, it apparently makes them softer and easier to handle!
@@RonaldFinger Thanks I did it. Took almost 6 hours from my life.
You missed one thing:
-lnstall the needle jet holder, noting the following:
The #1 and #4 carburetor has 0.7 mm x 14 holes [A]
The #2 and #3 carburetor has 0.6 mm x 18 holes [8]
I want to marry you
Do you mean emulsion tubes.....?
Did the exact same stuff, started it back up and 2 of the carbs seems to be leaking out of one of the screws on it(not the 4 that connect the bowl) is it a float issue or gasket issue? Any help please
And by leaking i mean pouring out gas
Fixed it, a while ago, need to fully push the carbs into the engine, thats the result if you dont lol
That's a nice zr7s, what year is it? I have a yellow 2003 at 46K km and just cleaned my carbs, with every part undone, went back to your video for reference for some tube routing I forgot hahaha
@ 1:45 ...May I give you some advice?
Be careful with that screwdriver. Keep your head/eyes always away from a tool/screwdriver.
To get those bolts off the carburetor easier...you could use a torch... that usually how I do it... :P
Why didnt' you clean the idle jets?
Lapse of thinking! It just completely escaped my mind
I need to do this on my ZR7s, Im not the most confident mechanic so this is really helpful.
A couple of questions.
1. Do you need to drain the tank, or do you just need to turn the petcock to off.
2.Where are the idle jets.
1) There actually is no standard off position on this bike’s petcock. The On and Reserve position is the “off” position. Fuel will only flow on those settings if there is a vacuum pulling it, so only when the engine is running. As long as it’s not on Prime, fuel won’t flow. So just keep it on either of the other two settings and just drain the bowls.
2) The isle jets are right next to the other two jets I took off. Basically just take out the three brass fittings.
I hope this helps!
Thanks for that, it does really help, its one of the main things that has been concerning me about it.
Now all I need to do is get some carb cleaner and a few free hours (the hardest thing to find :) )
.
Many thanks.
No problem! I know it’s intimidating at first, but once you get started it really isn’t that bad. It gets way easier after you’ve done it multiple times too!
@@RonaldFinger you know all the sizes and tools for taking this apart and synching the carbs as well? Bout to buy one of these babies and she will need a thorough cleaning
Hey JJ, I can't recall the exact sizes, but a standard metric socket set should be able to take care of the brass fittings and a screwdriver for the bowl screws. I've never actually synced the carbs when I did this, so I'm not sure what the tools would be for that.
Have fun with the bike though! I really enjoyed mine.
Did you end up having to resync the carbs?
That’s probably something that should have been done, but I did not. It hasn’t been running rough though! But to do this job the right way, I do recommend doing it.
Thanks! I have the know how, just not the tools or the time!
Definitely will have to balance the carbs.
Hey im working on a bike just like this one but i have 3 screwed that won't come out ive tried the impact driver and it just made it worse.. Would really appreciate the help...
Are using the correct screwdrivers, JIS size and form?
Yeah as Richard said before me, they are not normal Philips head sizes, you need the correct tool, and once you have them out get hex/allen bolts to replace them.
thanks a lot for this video
Also, it would be good to clean upper part of carbs. I can bet that needles are not in good position. They should be the same on 1&4 carb and 2&3.It seems that here there are same at 1&3 and 2&4. Thanks for video, but this is half done job. And lost of time if You leave it without sync.
Cheers!
I couldn’t agree more. Next time I own a bike, I’ll make sure to do that. Also, I should’ve made it more clear that this isn’t supposed to be a tutorial by any means haha. When I owned this bike, everything was very much a learning experience and this was just a video in a series of “this is what I’m doing” rather than “this is how to do it”.
@@RonaldFinger I watched it because I was wondering can I reinstall air box/carbs with tubes mounted on a/b. Clearly not! 😕
I do a lot of mechanics but sometimes YT is ussefull. 😊
P.S. I always put carbs on table, never do it attached on bike, it's perfect way to mix or lose something... 😂
wish i had the confidence to do mine
It might be a little frightening at first, but it's not so daunting once you start! It'll just take an afternoon at the very most, maybe a little longer if your float bowl bolts are all seized and stripped like a few of mine were. But impact drivers and heat are friends! :)
thanks the reply :)
Where are the other parts ?
water....what do you think it could be :)
Hmm? I’m not sure what you are trying to say
@@RonaldFinger the "thing" in the fuel moving side tovside
Ahh, okay! I never knew what that was. Thanks for letting me know! The bike ran perfectly fine for the next year of me owning it, it’s sold now, so I’m assuming no more got in there. Very interesting how it got there in the first place though
humidity in the air, rain water, and most likely...water in gasoline
@@RonaldFinger humidity, mostly. Water is heavier than petrol, so it gets to the bottom of the tank. This way it arrives in the carbs pretty fast :)
спасибо друг. senk you my friend)
HE Didn't remove pilot screws for cleaning. Typical amateurs with non-running bike afterwards.
He didn't clean jet holders side holes and idle jet holes!!!! Video how NOT to clean carbs. Bike will NOT run after this job!!!!!
Why couldn’t you just show the whole process
Why don't you remove the bank of carbs and work on them on the bench , your not helping yourself working upside-down on your knees .
