HELP! - 92 to 94 GWE [A] carbies

Post by PedroTQ » Wed Nov 06, 2019 2:27 am



G'day to Everyone! :D

I have put a pair of 92-94 GWE [A] carbies on my 88, all wiring and black box changed to suit,but she runs like crap up to about 2500 rpm.

There is a hose from the base of the left carbie but I don't know where it goes, I think it may be for the Secondary Air Injection circuit?

if so I can block it off as I have de-smogged her (much less hoses and crap to work around).


Can anyone recognise this hose, I have a service manual for the 88 and the 90 but don't want to buy another manual for the 92 as my funds are short.


Thanks in advance, Peter.

If my memory serves correct that hose goes to one side of the 3 way (one way check vlave) vacuum fitting for the flapper in the intake duct. It's on the left side of the air cleaner assembly on my 92 interstate.

That is correct. I replaced my 1990 carbs with a set of 1996.
The only differences from a piping point of view was this pick up for the IAT valve. On the 1990, and likely on the 1988, this pick up is located on the left manifold. This hose should be connected to either one of those points and the one not in use should be sealed. In my case, I choose to remove the spigot on the manifold and replaced with a M6? screw. I plugged the pipe at the carb.
Now if someone could tell me how to check if the valve in the air cleaner intake actually does open once the engine warms up, I would be very grateful as it would explained why my bike is running so rich...
I should take more pictures when I do those things!

Many thanks Gentlemen,

I had a feeling it was something like that, so I will just blank it out.

Here is how to check your Hot Air Control Valve. I removed mine completely, it never gets that cold here in the Oz.

Thanks for the reminder... I have already check the actuator and it seems to work. I will had checking the hot air control valve to my winter list... I am planning on replacing the "O" rings on the cross over tube and check the engine temperature sensor on the right intake/cooling tube anyway.
What I was asking is a way on making sure it is open when the engine is running and up to temperature... I'll find a way :D
