Title: Air mixture valve
Post by KINGPRAWN on 03.11.13 at 10:06:35

Is is possible to remove the air mixture valve? Building a cafe racer and have a different fuel tank. If I use a yamaha rd 350 lc fuel tap that has two outlets, could I blank off the vacuum connectors on the inlet manifolds and carry on as normal???????

Thank you... So until I have different fuel tap can I block the large vacuum pipe on the manifold to see if it's causing a problem??

You remove all the tubes, close hermetically the large pipe at the intake socket.
the two thin tubes, you connect with a petrol tap each tube.

Greetings from the UK.

I have a problem with the fuel/carb system on my bike. I think I may have a problem with the Air mixture valve. I was considering getting a replacement valve. But if the valve is not needed then I can simply remove it to diagnose the problem.

But the question I have is: if the vavlve can removed what does the valve do? If it can be removed then it didn't do much for the engine!

If I remove the valve and could be introducing another problem I would like to know what it my be.

Thank you
Kevin

You can removed it ....  but  you must close airtight, the thicker tube, which was for the Airmix.
Your engine no harm can get.
The valve was task to ensure, that when the throttle while it does not come to misfire.

Drive for years without the valve, and have no problems.

I've noticed on the onside of one of my inlet rubbers a crack, which was a split right next to the clamp making it invisible... Reckon that's my problem!?!?!?

Very, very likely! And if it may not be the only issue, it's at least part of your problems!

Just spray some brake cleaner or any highly inflammable stuff on this crack, while the engine is idling. If this makes the engine run faster, You are on the right track.

Good luck,

Stefan
