What else to check, carbs off

Postby kane67 » Sat Nov 14, 2015 10:48 am



Winter project continues...
Now I have carbs off, heat rubber off. Replaced one "modified" spark wire to new original. All coil wire connectors needs cleaning. Rubber hoses look ok (red) from intakes to ign unit, but I will put new hoses anyways.
Some carb hoses (white) needs replacement, some feels thin like it's about to brake soon.

What else would be wise to check/replace at this moment...?

check all of your vacuum lines, they are probably getting brittle by now. :D :D

Yes, now it's easy to change all... especially those under carbs and intake.
And new carb boots.

What a mess of tubing under there. I can hardly wait until this winter to tackle what you are currently doing. Good luck. :D :D

OK,

You have the carbs off - great achievement to perform that task. I would get new float bowl gaskets and the O rings for the accelerator pump assembly. When mine were serviced a while ago I had a strong smell of fuel and terrible economy - the O rings for the accelerator pump had deteriorated and leaked fuel, seeing they are a handful to get in and out - while you have them out - a strip and clean would be my recommendation. It is probably not necessary to separate the carbs unless you really want to.

Make sure all your jets are clear and all carby passages are cleaned thoroughly, blow compressed air and brake cleaner through. Pay particular attention to the two tiny jets at the tops of the throats (these are fed by the accelerator pump) - and you need to make sure these are pristine or you will have a stumble/lag when you try to accelerate. There are also very small O rings and springs under the idle jets - make sure you don't lose those, and one final mention - if your carbs still have the adjustment/mixture screw caps in place - remove the small lip over the cap that prevents them turning - you will need to adjust these once back on the bike, as well as the sync.

Replace all the vacuum hoses - make sure you replace just one hose at a time to get the right length.

Good luck with it.. :)

I'm going to check carbs, acc pump I did few months ago.
Today I replaced all tubes (white ones later when carbs are back), about 4 metres :D
There are few tricky place to replace (yellow).

The slow jets thread into the carb body and have an o-ring on the end that seats into the jet holder. The pilot screws have a spring, washer and o-ring
and one final mention - if your carbs still have the adjustment/mixture screw caps in place - remove the small lip over the cap that prevents them turning - you will need to adjust these once back on the bike, as well as the sync.
If OP removes the float bowls, it's better, imo, to grind down the boss on the edge of the bowl instead of messing with the limiter cap flag. If they don't have the limiter cap, grind the boss off anyway. It can keep your slotted screwdriver from turning when you adjust the mixture

More than a few ;)

BTW, I was looking Honda manual for mix screw adjustment, noticed a SW model mentioned as in vacuum line drawing also... book says SW is Switzerland model :idea:
I have that AICV Valve in middle of carb boots so I must have a SW model?

My bike is imported years ago, would never guess it's from Switzerland ;)

Swiss frame numbers are SC22-2000934 through SC22-2001743 and the engine numbers are SC22E-2002438 throughSC22E-2008950

Ok, engine matches Swiss numbers. But where can I find frame number? It's not VIN number or...? VIN number says it's US 49-state model 1HFSC2209...(3/88).
Sticker and right side steering head matches. Last 7 digits are -A005420, maybe a engine swap?

Carbs under work today, bowls already done so no need for grinding. Limiter caps still there.
Looks nice and clean inside. Tomorrow will clean passages with brake cleaner & compressed air.

Original 50 slow jets, planning to update 55's...
I think the -88 recall was not done, can't find any X marks in frame.

Then float level check and parts back together.

Carbs are done, all vacuum lines done, packed back and project continues...

Forks next, first one done. Disassembled totally, cleaned with brake cleaner, also antidive.
New bushings and seals, made a hole to cap so easier oil change next time ;)

Last saturday got engine running, all good. So my project did go well, no extra problems because of me :D
Synchronized, adjusted fuel mix and again synched. Runs nice so I'm happy.
Pilot screws now 2 1/2 turns open (replaced slow jets 50 => 55). In this bike the -88 recall is not done.

Replaced timing belts last week.

Steering head cleaned and lubricated, last thing left is front brakes. Ordered new EBC rotors, I will replace all seals to calipers.

You might want to order some EBC pads for the front as well. From what I have heard, the OEM pads will wear the EBC rotors quickly. I have had personal experience with the EBC pads on the front but not their front rotors. I did have a rear EBC rotor on my '99 and I always used the EBC pads as recommended by a local mechanic. The wear was not objectionable.

In the front, I had the EBC organic pads and they would typically be in need of replacement within 16,000 miles. I never tried the sintered pads for fear of wearing the rotors too quickly. Pads are a lot cheaper than rotors ;) .

I now stick with OEM rotors and pads. With OEM the wear is predictable. The pads will last in excess of 40,000 miles and the rotors will last well past 100,000 miles in my experience.

Yes, I did put new ebc semi-sintered pads rear and will put semi's to front.

Noticed yesterday that one tube was not connected (right side to close rear brake switch).
Damn, I forgot to connect carbs bowl drain tube :x

Well, with a "dentist mirror" and small hose pliers I manage to connect it under carbs :D
