Balancing Carburettors With Home Made Manometer




What do you think about this video?

Bajnokable: Red White Green= Hungary :D

Conrad Kritzberger: Correct:  Your narrative of what you did with the carburetors (left/right or front/rear; leaner or richer fuel mixture) is EXTREMELY non-existent.  So, you're leaving it up to "us" to experiment... without giving insights as to what you're doing with the carb adjustments (up/down... to raise or lower one side or the other.)    Poor narrative.

kfs240sx: Hey man this helped me so much thanks for explaining so well great job on the video

Clay Atkins: Good job, I should make one of these for myself. very handy.

Dan Barclay: sirhaggardly - you make a four bottle version

mike smith: Nice pretty smart to know how to do this.

Timosbi: just got a virago 400 did your manometer trick with two coffee jars. it worked perfect! it was easy.  Thank you   

L2fish: i had a spearco water injection system on a camaro.  they got it from the ww2 aircraft

stephane talbi: Thank you for the carb sync. tool, I did do one exactlely the same and used it on my v-star, works just perfect, I'll keep this precious diy Tools and show it to my buddys
Thanks for your help Steven

ThrasherGnar: moron lol

David OToole: Agree with RedNeckHippie.

David OToole: Concerns about fluid getting sucked into engine. Only use sufficient fluid or position the tubes so that when one is nearing the top the level of the other falls below the tube (and is then sucking on air). Tape them or fasten them to a board or box so theat they can't fall over. Elsewhere people have questioned the use of water and suggested petrol.. DON'T. It is NOT the nature of the fluid water/oil but the incompressability of fluids which will cause problems in any case.

David OToole: Two comments: As far as I can see the carburretors will be balanced when the level is UNCHANGING (indicating that the pressure above each fluid is the same). NOT when the fluids are at the same level. HyzerGlen says this but it is easy to miss. Also - He says that when they are in sync the revs DROP to their lowest level. This can't logically be right. When they are in sync they will work better together. Shouldn't the revs rise? Not a good explanation of how to make it but still very useful

jimmy Forero: VERY VERY BAD CAMERAMAN!!!!!!!

phxxr650r: hold the camera still

redneckhippiefreak: Water is used to clean the head and valves and in some cases adds power.. no harm just a lot of back fires and sputtering if not atomized correctly.. The old spitfire planes got that name from the WATER injection system that added lots of horse power. " Push the button and climb like a wild cat" was an expression I've heard when relating to these systems.

Jerrold Adler: Here's a tip for making this setup a little safer: Don't use water, which will suck water vapor into the carb (changing the mixture) or suck actual WATER into the carb if the bottles get tipped over (you don't want that). Instead, use Marvel Mystery Oil or a similar oil-based additive. One: It's red, which is good for visibility. Two: if it gets somehow sucked into the engine, it won't hurt anything! It'll just burn with the fuel, maybe smoke a bit.

davnroxie: Absolutely brilliant! I have a 75cb750 That I have had for years and I know the carbs need synced. I can't wait to try this!!!

Brenton Telford: I have set my mixture screws to the recomended setting then i played around with that til the bike felt the most powerful

Brenton Telford: Thanks Dogastrophe, I ended up figuring that out and making the design successfully but does he change the mixture screws or the balance screw? I ended up bench balancing the carbies (taking them off and using a needle to adjust the butterflies to open at the same time) and the bike runs much better and kets an extra 20km's per tank..Is there a way to use this method with the manometer to adjust the mixture screws or is it just for the balancing?
