Removing restrictors on a CBR600f-y

[Noxious89123]

Is it a big job, or do-able by a novice?

I haven't done any major mechanic typ stuff myself.. biggest thing i've done really is to adjust my chain tension

I've no worries about taking off the air duct covers and getting the tank levered up, that looks rather simple (haynes ftw).

It's fiddling with the carbs / airbox that has me a bit uneasy.

Any advice?

If it's a carbed one, and just washers, no problem.

Tank off, Disconnect associated gubbins which are connected to each other, (air box lines/bits of seemingly unimportant rubber which you later will realise ARE important)

Airbox off(if it is under the tank and above the carb)

Take the entire carb assembly off from the intake. Washers sit inthe rubbers between the whole carbs and the head (I think)

This was how it worked for a zxr400 I helped do the other day, can't be that dissimilar

If you google how to balance carbs on your bike model, you can probably find a step by step guide of how to strip down to your carbs, then its a simple case of carbs off, rip those washers out, then put back on. You can do it from a haynes, just if you do, get some postit notes, go through and find exactly what you want. It's annoying fiddling with oily fingertips trying to find the page when it says 'now refer to chapter 9'

No help on restrictors.

I've got as far as taking the top off the airbox in the past but wasn't brave enough to take it off. I'd suggest a couple of things.
Firstly, make sure you have plenty of padding and an extra pair of hands when getting the tank off, I chipped the paint on the bottom seams of the tank rather infuriatingly.
Secondly, it's probably worth inspecting/changing the plugs whilst you have it apart as I think you need the airbox off to do that.

Just a bit more info for those interested, my restriction crt. says this;

Device: Inlet blade + Carb Caps
Device code: 02-PC35-K25
Device details and dimensions;
Outer diameter = 44mm
Inner Diameter 1 = 11.5mm
Inner Diameter 2 = N/A
Hieght (thats how it's spelled ) = 22mm

Max power = 33bhp @8800rpm
Max Speed = 96mph / 154kmh

Inlet blades! EDIT: Ignore this, i was wrong. I'm a noob.

I thought i could get them out by removing the top black part, and removing the air funnels. Turns out it's not that easy, it's slightly further into the carb than that

Might have to take the "top" (front?) of the carbs off, which seems alot bigger job!

Dunno if there are washers between the carbs and heads, will find out if i can work out how to get the carbs off! Seems to be alot that will need disconnecting, ehich i'm trying to avoid; Was hoping i'd be able to just lift them up an remove the washers with out any major dissassembly of the carbs, or removing all the fuel lines, air hoses and coolant hoses.

EDIT:

The "inlet blades" seem to be just before the butterflies. I can't remove them just by removing the air funnels, they're just inside the actual body of the carb.

Do i need to remove the carb top, and the piston/diaphragm to get these out? More importantly, can i partly dismantl the carbs without having to disconnect fuel lines / coolant hoses etc?

Hope for a fast reply! Want to get this sorted in the morning.

You shouldn't have to remove the stacks, all you're trying to get to is the inlet manifold locking rings, which sit directly between the bottom of the engine and the carbs.

Undo all eight of them using an ELS (Excessively Long Screwdriver) and rock the carb bank back and forth until they pop off. You might have to remove the choke cable and bracket at the front of the carbs, but there is no need to disassemble the throttle cables which run up through the centre of the carb bank.

If it's anything like my F3 then you'll also need to remove the centre fuel feed t-piece and the carb heater pipes at the thermionic valve end which is bolted to the engine next to the starter motor. If you have to do this, drain the coolant first.

Be careful with the rings, they mash real easy, if you've rounded any of the screws off getting them out it's always a good idea to buy replacement ones from honda, they're about 2 quid each. Even tiny air leaks will trash your fuelling.

I tend to replace them as an entire set if I've rebuilt engines or carbs if they've been in situ for a few years.

I was advised by the gf's dad to use lots of vaseline on the inlet rubbers, to help get them back on the heads.

Wouldn't this then get drawn into the engine and do funny things?

I'm out of my depth a bit here

Might just do the CCT and put the rest back together and get a mechanicly minded friend to help me do it.

Atleast now i know how to get the tank and airbox off

Apparently those black things are the "slides" and they shouldn't be removed.

I'm not really sure, i'm not a mechanicm i'm just going by the haynes manual.

Doesn't show them in there! Just had a look at a microfiche for this bike, he was right

Just as well i never got as far a removing them then...

Got the carbs off the engine, but cannot for the life of me get the rubbers off of the carbs, to remove the washers.

Put them back on now, and am just going to do my CCT, and do the derestriction at a later date

this has been quite fun to read

usually, the inlet manifold rubbers stay on the engine, and the rubbers are released from the carbs.

you have got the carbs off the EXTREME hard way.

Just levered them out of the carb rubbers with a 1/4" drive short extension bar. There is a small lip inside the rubbers, that mates with a groove on the heads. The washers sit just behind that, quite snug in place, but very easy to pop out.

Won't be selling them, might need to put them back in at some point.

Will go measure them now... Wouldn't be hard to make your own tbh.

1mm thick steel, 42mm OD, 7mm ID, 3mm ID for the pilot hole.

Haha, this may come in use

So now moves like shit of a shovel now eh?

what are the inlet blades?
and where are the blue spots on the CCT as mine makes a racket too! am properly going to get a manual CCT

in future, make sure you remove the rubber manifolds.

you can literally lift out the restrictors then, rather than prising them out with tools that will potentially damage the rubbers.

i had to do the same thing when removing the restrictors from my rvf the other day, of course we spent ages looking in the carbs for the restrictors and gave up for the day only to find out that the washers were below the carbs and were in plain sight the whole time

Even if you fully loosen the clamps, or totally remove them, the rubbers are an incredibly tight fit to the carbs.
