Hey guys,

My MC22 runs great but I need to use the choke to start it even when it isn't a cold day, and I need to use the choke for atleast 30-40 seconds before it will idle properly so I thought it might be worth giving the carby a clean..

What would you recommend for cleaning the carby? Just use a compressor to blow crap out of all the small holes, and then scrub everything with a toothbrush?
Do you let anything soak overnight in petrol? Will I need a manometer to balance them? (I heard this is optional) Are there any parts of the carby I shouldn't bother taking apart/cleaning? Do I need to take all the floats out and clean them as well?

I PM'd studricho about the O-ring kits.. and asked if he sells the jets as well.. If he doesn't, does anyone know anyone who sells the jets as well?

Cheers everyone

EDIT: If any noobs have cleaned their MC22 carbs, any advice? How did you go?

I presume you've seen the existing thread.

The thread off the old forum is pretty informative as well.

Get a tin of carb cleaner from supercheap or whoever. Either spray and clean as you go, or put the carbs in a container filled with thinners to clean out the gunk. Use a toothbrush if required. You can use petrol if you want.

Manmeter not required unless you play with settings etc.

Generally the float seat is where the bits of rust or gunk accumulate - its like a little filter gauze thing (it is on the GPZ anyway).

Good luck. POssibly before you do it though, use a fuel additive - it may save you a lot of hassle, but from the symptoms you mention, you may just need to bite the bullet and clean the buggers.

If it's rubber then try not to get any carby cleaner on it. Especially the diaphragm rubbers. Actually remove them for the carby complete to prevent any getting on there.

Wear safety glasses when your using carby cleaning.

Personally I take the bare carby body to my local carby joint (In my street, very handy) and they blast them with some special junk after they soak in their soup over night.

I've been using this method for years and never had an issue, much more affective than the old spray carby cleaner.

That's my opinion anyway.

It will be good to gain experience, but I'm not too sure that your bike will start without choke after you do it. My carbs are pretty clean and they still require choke, for about as long as you said you use yours for, on all but the hottest of days.

So take the rubbers out and leave in thinners overnight and then scrub everything seems like the way to go. Yeah I could use the spray but I might as well go the whole way and clean everything properly.

Probably a noob question, but where can I get 'thinners' from?..

Cheers[hr]
Yeah, well experience is one of the reasons I bought an older bike as opposed to a newer bike such as a Ninja (plus I heard they handle shit).. I want to get some experience before I get a bigger bike. I don't want to be one of those guys that has a Desmo and doesn't know how to change a headlight bulb..

On a carby cleaning vid on Youtube I heard you can't use a wire brush on the jets because they're made of brass.. Are the MC22 jets brass? And are they the only part a wire brush shouldn't be used on? Or should I just use a toothbrush for the whole thing?..

Are there any decent carby cleaning vids out there? I might even see if someone on these forums would be willing to help out for a carton or something.. I'd rather pay for someone to help me than for someone to do it for me, and not learn how to do it myself..

Cheers

im gonna try and clean my carbs tomo
i'll let you know how i go

 

[aj26]

air compressor, tooth brush (used), carby cleaner

I wanna goto a re-carb day !! like last year

 

[banana.logic]

Yeah don't use a wire brush, I think most jets will be brass. plus the carb body is a soft alloy so I wire brush will be too abrasive

 

[SeeBeeR]

I have to bring this up since im a noob.
Anyone use those fuel additives carby cleaners? Obviously nothing beats a scrub down but just wondering if they are worth the money for a quick fix carby clean solution.

 

[banana.logic]

never used them, but once you get the hang of cleaning your carbs, it ain't no thang...

I would say NEVER use thinners.... they will turn an o-ring into a fruit loop in no time... seriously... don't use thinners, especially don't soak them in thinners. You will soon be pulling apart your carb bank to install new o-rings in the t-piece for the fuel rail....


ps. NO THINNERS!

so do you reckon its alright if i use thinners?

lol a mechanic told me to use thinners.. but i dont really know what 'thinners' refers to.. and even though Im getting an O-ring kit from studricho I still won't use the thinners. im sure a good scrub will clean the carby just fine.

Cheers
