Balance Bing CV Carburetors

[@tomphillips2608]

I watched with amazement as a gentleman balanced the twin D'ellorto carbs on my 74 R90s many years ago. He'd use two screwdrivers while putting his head on the gas tank. When done, the idle was silky smooth. I asked him to teach me. He'd laugh and say that he couldn't explain it. He was service manager at a local BMW dealer. If his old bike(with the Earls forks /2 I think) didn't fire with one kick, He'd tear into it. Great video, BTW. Thanks

Great video, love that home-made manometer. Useful idea to build your own spark plug extender, I was shopping around for those with no luck.

Very informative video. As well as smoothing out the engine, I’ve found that setting the air/fuel mix correctly is critical in preventing the engine from wanting to bog out and stall when lifting off idle. Have you experienced this with these carbs?

I will try to answer as I helped Brook with the video. Yes,getting the air/fuel mixture set correctly will prevent the "bog" just off idle. After i finish the carb balance, I go back and double check the idle air/fuel settings, once I'm sure they are correct then, double check the balance again, as idle air/fuel can affect the carb balance. It is a "balancing act" between all the adjustments. We have developed a written, step by step procedure. If you are interested contact me and I'll email a copy.

Nice video! Try to get yourself a Katdash Harmonizer. You won’t regret it

I have the Grok, harmonizer, which is what Katdash got rights too after he died.
