Running on one cylinder... Honest opinions

So I decided to pull the carbs off my bike to check them out so how nasty they were. I knew that they were causing a rich fuel condition because all my plugs were fouled with gas. The thing is that I have pods and straight headers. So I pulled them off and cracked them open. They look like they have just been cleaned. I did a clunk test and it passed with flying colors first time. I didnt get a chance to really check out all the little passages but I will get to that tomorrow. The best part is the jets sitting in it. I knew they had to be big because it is running rich. They had #136 main, and #40 pilot (stock). I just recieved my #126 main, and #42 pilot from Chacal today. Which is the correct size according to Chacals chart. So I am pretty happy that I found my root to all evil.

 

That's not the root of ALL EVIL, ....

If you want to have some fun with those Carbs; "Vent" them.

Seal the Kidney-shaped Atmosphere Vents on the Intake Horns.
Fabricate Atmosphere Vents - (2)
Connect 1 & 2 ::: 3 & 4
Drill into side of Horns.
Add Hose - T - Grommets etc.

Atmosphere enters GREEN Opening between Carbs and satisfies the need for Atmosphere allowing the Diaphragm to react to Vacuum and MOST IMPORTANTLY ... Flow through the Main AIR Jet to the Void surrounding the Emulsion Tube.

 

Would you really recommend drilling into the carb bodies? If so what supplies would you recommend?

 

NO. This is an untested, theoretical idea. While Rick's theory seems sound, nobody that I know of has used it successfully as yet, and it's untested to the best of my knowledge.

If you're going to do it, I wouldn't do it to my only rack of carbs. Reversing it would not be easy.

I'm surprised to see it actually being "recommended" rather than posed as the theory that it is.
