Whoever invented those long reach pliers needs a medal, I have them, not used that often, but when you need them, you need them! Its a good thing the hose burst when the bike was not on the road !

[@harryw9598]

at 3:05 the (2?) liitle black box on the right, inside is a filter, over time it falls apart, and pieces get inside your cabs, replace / check it

[@stuartbailey9941]

Fate is strange! Had that hose blown on a ride and wasn't noticed in time, the consequences could have been disastrous. Your videos are improving all the time. Very enjoyable, thanks for posting.

[@davidsandilands1285]

Great vid, customer was very luck you picked up the leaky hose, could have been very inconvenient and expensive if it had blown while on a trip out.

[@themobilemotorbikemechanic]

Thanks 👍

[@boardwalker72]

I'm impressed with your skills, information delivery and also that you are happy to leave the little mishaps in as well. Looking forward to your future endeavours. Excellent work Steve. 👌

[@RoobieRoo2]

lolz as a gas installer it reminds me that things are hardly ever ever ever straight forward. Good to see that other engineers also get roasty hands , all the best Steve to you and all the ones you love!

[@themobilemotorbikemechanic]

Things get a bit hot sometimes but you just have to get on with it

[@arnoldhausler7039]

​@themobilemotorbikemechanic , could I please get your number my bike is I'm need of carb trouble shooting

[@PaulMappud]

It was that pleased it's carbs were in sync at last that it wet itself... 😂

[@leavemyrightsalone]

That could of been the mechanic..😆

[@unexpected.suffocation5175]

Good day, Sir. How did you manage to get to the carb middle balancing screw? It looks like you skipped this episode in the video. I could get to the middle carb balancing screw only while rolling on a throttle a bit and it was very difficult. Please, share with us the way you did it. Thank you.

IIRC, vacuum ports on carbs #2 and #4 are blocked. #1 goes to the fuel shutoff and #3 has 2 ports. On carb #3 one port goes to the fuel tap and the other goes to the PAIR. This is a 2003/2004 bike you're working on. Absolutely luv that Candy-Apple Red. And, yes, getting the tank off can be a little, repeat "little" awkward with the vacuum hose and 8mm fuel hose. The cracked coolant hose is just a 90degree 1" (25mm). Cut the legs to suit. Little wonder a 20year old bike has rotten original rubber hoses (vacuum and coolant).... So...to the owner.... PULLEAZE REPLACE ALL RUBBER HOSES!

[@fuzzybrain8274]

I have been scratching my head over this too... I dont have that hose set up on my 99.

[@N269]

@@fuzzybrain8274 Ok. I don't have a 98/99 set of carbs to compare, so I'm a little useless there. Does the Haynes manual help? Have you a copy of the CB600F-W service manual? (it's available online). On the 2005/2006 the vacuum on carb #2 is on the head, not the carb, way underneath.

[@N269]

@@fuzzybrain8274 Sorry late reply. They (Honda) changed the carb system (vacuum lines) in 2003 then again in 2005.

[@thomasedward9065]

Loving the higher quality of filming and you have someone doing the camera work so you can get on with the job in hand but if possible like me others might like to see more close up filming has I like to see what's what how and where etc but other than that great work

[@themobilemotorbikemechanic]

Thanks for the feedback. The camera lady is improving but first and foremost we are there to work so sometimes it is difficult to show everything when we need to get the job done.

[@dannyhaigh472]

Have the same engine in the CBR F3, an absolute ball ache to put the caps back on after a balance, need some long needle noses!

[@willswheels283]

Just found your channel, interesting viewing, that’s a nice example of a Hornet. I own and ride an old Honda NTV650 Revere, one of the best bikes I’ve owned despite being old and tatty. Nothing on a bike or car is ever as simple as it looks when it comes to servicing and repairs. Good video mate.👍

[@themobilemotorbikemechanic]

Thanks for watching

[@1234567marks]

This channel is getting better all the time, it’s damned difficult to make a good video, I know because I’m starting my own channel and I’m usually happy with about 20 percent of my footage when I’m editing , anyway keep up the good work 👍 PS , where are you based and what radius do you travel out to?

[@themobilemotorbikemechanic]

Thanks for watching and commenting. We are based in Leamington Spa, Warwickshire, UK and cover the Midlands region.

[@fuzzybrain8274]

Fabulously informative video. Thank you for doing this. I will book you when I get stuck!

[@LeeremiteR]

Great work! Can please share the vacuum hose brand/type you have bought? Maybe a link too? That would help me a lot, as I am about to replace my vacuum tubes. Thanks!

[@themobilemotorbikemechanic]

It’s just 3mm vacuum hose, nothing special

[@jesterxfan]

if you didn't have a vacuum issue like you encountered here, would you have first removed and cleaned the carbs (pilot jets), then moved to a carb balance/sync?

[@themobilemotorbikemechanic]

Yes most likely.

[@EvendimataE]

its my first tim to see sliders that big

[@paulbudford]

That's unfortunate. But better for the customer to go now. Then when he is riding the bike later.

[@arnoldhausler7039]

Have you got a number for the buissness? Need a hand with my honda Hornet!

[@themobilemotorbikemechanic]

Contact details can be found on Google 👍

[@williamfitzpatrick7248]

Another top job

[@davidkirk9187]

Glad that aged hose decided to let go at standstill would have made things iffy if it had peed coolant over rear tyre on the go 😢

[@chr11sf]

👍

[@chrisscott1547]

I've never understood why 4 cyl 4-strokes in cars can use 1 carb but motorcycles need 4. Carbs can be a real pain - and 4x is just that much more fun.

[@certainlynotvin]

🎉🎉

[@imoldgreg13]

😃

[@SuperbikeSurgeryTV]

Why in gods name are you increasing the idle speed to balance the carbs? You need to be doing the exact opposite! The correct procedure is to reduce the idle speed as much as possible, this amplifies any discrepancy in balance between cylinders. And at that sort of RPM you are nowhere near running on the main jet 😂 You are 100% still on the idle circuit. And what's the main jet got to do with the synchronisation of the carbs anyway? You are measuring inlet tract vacuum in relation to butterfly position at idle (although not in this case because you've set the idle speed way to high) 😂

[@SuperbikeSurgeryTV]

I think the misunderstanding comes from various workshop manuals saying that an increase in RPM is required, this is to smooth out the readings seen on the vacuum guages. 2-3 hundred extra RPM is all that's needed. Once the carbs are balanced, you should reduce the RPM to the point of stalling to make any final adjustments. The better set-up the carbs are, the slower it will comfortably idle. Obviously, then set it back to the normal idle speed once you have finished adjustments.

[@themobilemotorbikemechanic]

Thanks for watching the video and commenting. This is the way I was taught to balance carbs and have been doing so for almost 30 years. And you’ve also answered your own question in your own reply. Raise the revs, balance the carbs, drop them back to tick over. Thanks for watching 😊👍🏻

[@SuperbikeSurgeryTV]

@themobilemotorbikemechanic By a couple of hundred RPM at most, not 2000! and even then, it's usually not required. Having a bike revving like that on it's stand is a guaranteed way of getting it to over heat. There's no way the cooling fan could keep up.

[@Alien937]

Carbtune instructions, say to adjust the carbs at 1,500 rpm, also make sure the idle stays at 1,500 rpm as you make any adjustments, then reset the idle after to whatever your manual says.

[@adivarso8175]

Didn't you see the part with the vacuum hoses that were needing replacement due to leaks? Get off your high horse for a second and offer some help instead of giggling like a little bitch, you are not the be all and know all you like to think you are the fact is carbs are set from the factory and they don't even recommend touching them, but of course we're going to ignore that and rebuild them , stick them in the ultrasonic, sand blast them, powder coat the float bowls change out the jets, mess with the needle height etc etc no one is an expert on these there's too many variables. OH and. At least he's not a whiney little troll going around hating..He did what the customer asked him to do end of story. to be honest you've surprised me I didn't realise you had a dark side like this you come across as an amicable laid back type of person but hey what do I know about human nature! i'll be unsubscribing from your channel.@@SuperbikeSurgeryTV

[@livewire..]

I would never suggest such a repair on that hose; the hose is obviously rotten, a safety issue and a liability. I have no doubt there are other hoses and rubber components that may need replacing. Are you licensed and insured? You are doing yourself and your customer a service by refusing to make irresponsible repairs.
