Title: CARC ICV Bypass
Post by: tris on February 05, 2018, 06:37:33 AM
Did anyone who put a valve in the line also loose the ICV completely and fit a Tee connector, but leaving the ICV electrically connected?

My ICV is playing around and I'm trying to avoid the £300 for a new one until I've explored the other options

Cheers

You can do that but you need a valve to crack open a bit to let in air for it to start cold then close it off once warm.

Could someone explain the above for me?
Electrical connection to the Carc?

CARC vintage bikes.
Idle Control Valve. (not an actual CARC thing)

I didn't bother removing the stepper motor, I just plumbed the shutoff valve into the hose going to the airbox. The stepper itself still works, just not like I'd like it to.
I turn my valve open for cold start, then when the popping on decel begins I close the valve and am good for the rest of the day.

Jeez that's a pain in the arse to have to do.
Is it not possible to clean the old one ?
Pete gave me a new one  :bow: and since he and Beetle have had their grubby paws on it, the bugger runs as clean as a birds bum.
No more contamination of the stepper.

2007 Griso
Should I pull the stepper off and clean it while I have the tank off?
Does it come apart?
Pulled the pump out, someone has already done the metal filter thing.  :thumb:
Cleaned the ignition switch, that's no easy task.

Peter

Its had carb cleaner shot through it
The valve bit stuck in a ultrasonic cleaner and buzzed
Plus I hooked it up to a stepper controller and ran it back and forth

On the back of that little lot it appears  to work OK on the bench - except that it leaks a bit one side.

If its idling OK them probably all good

If the TBs and ICV haven't been cleaned recently though its worth doing - there's a MG Service Note that says you should but I can't remember where I found that

Thanks Tris,
                 No it doesn't idle that consistently although it may be better than it was (parked for a year) so I will pull it off and give it a blast while I have access.

I'll do the TBs as well I guess

The list keeps getting longer.

Strange that isn't it

One of the reasons I sold my 95 Cali was because I got fed up with fixing it.

I've had to "fix" the B11 loads more than I did the Cali - pesky electronics.

Still I had some good news the other day. The LCD on the dash suddenly burst back into life!

So it must be a dodgy connection and a good candidate for Carmo to heal - permanently

Good luck with the Griso I love my B11 when its on song and I'm sure the Griso will be as good
