Noticed this when removed the carbs... expert advice needed

[Stepkevh]

Decided to do the cleaning of the carbs and meanwhile set the TPS as suggested here at 500 ohms.

So i took them off and checked the resistance of the TPS, i was shocked to see a whopping 1076 ohms


Followed the guide here and after some fiddling with the lower leg of the valve i was able to get it at 497 ohms
I bended the leg because i didn't have a dremel at hand, lowest point was 385 ohms
So first mod is done

Next i turned the carbs upside down and noticed this



The other carb has those nozzles as well (also cluttered), they are connected with eachother with a hose and go seperatly to the waterpump.
As i could guess already those cluttered holes aren't normal because coolant has to flow trough it.
But what are they exactly used for ?
Is it to cool down the carbs ?
And most important, what caused it to clutter those holes ?
My guess is that it comes from heated up water and the "chalk" that sticks together....
Any advice is welcome

I believe the water from the engine to the carbs was to warm the carbs up in cold weather
I think some people have removed them to make work on the carbs easier and have noticed no different
In the bike
I would get the two working or remove it from them altogether
Good job on the tps
Have you look at your cct and regulator yet

[alanfjones1411]

Hello and welcome to the forum.I also think they are to stop the carbs icing up in cold weather.

[Stepkevh]

Was already cleaning all the clutter out of those holes and the tubing so that the coolant is able to flow properly

I noticed that the regulator was already changed by one with cooling ribs just need to check which one it is exactly.

The CCT's havent been checked yet as the engine ran properly without chain rattling.
But as i dont see any colored marks on them i'm not sure if it still are the original ones.
Can hardly believe it that it are still the original ones as the bike has 59000 km's on it (36660 miles).
But will check them anyway while i'm busy

[macdee]

you cant tell when a Honda cct is going to give up the will to live
best options are to do the stopper mod or go for the mcct either of these will save you a rebuild

[Stepkevh]

Will do one of those anyway, dont wanna risk another engine like with my first Storm

While further stripping the carbs for cleaning and checking what jets etc i had i noticed this



Shouldn't there be a washer under the needle and no it didn't keep hanging in the cap i checked
Is this the reason why it smells like it throws out fuel trough the exhaust, running to rich in idle ?

[macdee]

That's a standard needle no washers under it if I remember right
If the carb is rich then a washer under there would make it richer
I would check out the workshop for card set up
Hawk does a good standard set up

If you want to lean the mixture the fuel screw could be the way to go
Info also in the workshop

What air filters are you using

[Stepkevh]

Well i checked all the rest of jets and mains and i see numbers like 48 175 178.
So thats all standard as well
The airfilter is an orange/reddish aftermarket one, it was in there when i bought the bike.
Eventhough it looks like rats have bitten in it, dont know what the previous owner did with it
And i know the standard airfilter is grey/black with alu mesh over it
So i will install a new one either way.

I checked the workshop for settings of screws and i saw 2 1/4 turn and 2 1/2 , 2 3/4 (front / rear carb)
So i did set the screws that way, probably need to turn them in a bit by bit.
That's something for when i can make it run again.
Going to check CCT's first and do stopper mod while the bike is stripped

[macdee]

If you don't want to spend lots of money on dyno time and jet kits
Put a standard air filter in and standard jetting
Then tune what you have
Standard carb works best with the standard air filter

they normally go just after you join this forum

Well, a good thing i'm not driving it yet as i'm waiting for my plates.
Meanwhile i'm doing a good checkup.
So wanted to look for the CCT's today, everything removed, removed camcovers.
Set the timing on the RT mark for the back cilinder.
Check the markings on top and guess what ....



They aren't even lined up
So i know what to do next... put everything on time again

[tony.mon]

Yes, just reset the cam timing on both cylinders, following the guide in the workshop knowledgebase.

I followed the KB guide for installing MCCT's, saw the pictures of the markings there.
That's how i knew directly that it wasn't correct

[Stepkevh]

The back spark plug doesn't look that good either anymore.
Completely burned black and a verry tiny white tip
