I attempt to synchronize the carburetors on my Suzuki GS550, but run into a problem. All the steps for doing a carb sync are here however. In my particular case I get derailed by an ancillary issue.

Thank you for giving me hope that I may not have to tear my carbs apart until I fiddle with the air screw.

Great video,I've nearly finished a year long restoration of my 76 water buffalo, & i had a fuelling issue on initial start up,& I sent a set of carbs off for a refurbishment & I found a video on KZfaq channel classic octane , he showed an in depth instructional on stripping & repairing a set of Honda cb550 carbs, I watched it through twice & thought,maybe I could do that,so I have a spare set of carbs from the water buffalo so I stripped & cleaned them through & put all the slides & the tops back on, then set up the intake butterflies, I'm just waiting for 3 keyster kits to arrive,and right in the middle of my restoration I bought a 1978 gs550, non runner, mainly sorted,just a clutch/pushrod problem to sort.

I'm familiar with Tyler's channel. I've been a subscriber of his for a while and recall the episode you mention. Yes, I'll be tearing these carbs down and cleaning more thoroughly. Was trying to avoid splitting them as new fuel rails will run me $50, but seems it'll be necessary. Was a risk I took and this time it didn't pay off. No biggie. Fun! 🙂

Thanks for your response. I was amazed that for your having rebuilt the carbs, the one wasn't delivering upon start-up. I've had those "cold exhaust pipes too...and was wondering what you did to address that problem.

@UrbanMonkTV 2 жыл бұрын

As I recall it required more tweaking of the air and fuel screws on those cold cylinders and eventually they got fuel and got hot. It's been a long time sorry.

Hi, I had the same problem on cylinder 4th cylinder 1 - 3 had 240 degrees, No. 4 only 50 degrees. All cylinders had ignition sparks and all had fuel. I experimented a long time until I changed the complete carburetor No. 4. Now I have the same temerature on all the bends Greetings from the Bluesky

Makes me want to build a custom intake and run a single carb on mine.

@UrbanMonkTV 3 жыл бұрын

That would be a fun project! With the airbox removed, there's plenty of room under there. Maybe throw in a small aviation turbo while you're at it. 🙂🚀

Had would you do a dual carb hs 550 only have 3 vacuum connections on cylinder 2 it's sealed completely.thanks

@UrbanMonkTV 2 жыл бұрын

I'm not familiar with your specific machine, bit you'd only need 2 connections for 2 carbs. Just be sure they are between the carb and cylinder head and they are the same on both. Use only 2 gauges. Sync the same way. Thanks for watching!

What was your final jet sizes and what were they stock

@UrbanMonkTV 3 жыл бұрын

Only change I made was mains - 80 to 95. I don't recall the secondaries offhand, but I left them stock. Altitude at my shop 830 ft. Uni-Filter pods and Emgo mufflers.

Isn’t the intake vacuum a little low in this video?

@UrbanMonkTV 2 жыл бұрын

Thanks for watching. Yes, with the pod filters, intake pressure is reduced while volume is up. This the need for change in Jets and air screw settings. Once it is running and warmed up she runs great.

Hi UM, Fantastic video really helpful! I have identical issues with my GS550E here in the UK. I have done a compression test, results as follows: No1 95psi, No2 95, No3 100, No4 100. Yours is considerably higher at 150 is this because you have fitted high comp pistons or has mine got a problem? No3 on mine isn't firing either & is running cold when measured at the header pipe. New plugs fitted all sparking, did you cure yours by turning the fuel screw out underneath to allow in more fuel? when I adjust the air screw it has little effect. I have vac gauges, colour tune & an ultrasonic cleaning tank so carbs are clean. I'll be in the man cave tomorrow trying again your feedback would be appreciated. Cheers Rob

@UrbanMonkTV 3 жыл бұрын

Hi Rob! The good news is your compression numbers are very consistent across all four cylinders. However, they are getting pretty low. Mine are higher because I rebuilt the top end of the engine (honed cylinders, new rings, ground valves/seat). I kept everything stock though. Given your carbs are clean...Yes, you can open the fuel screw underneath to see if you get #3 to fire. Best of luck! Enjoy the adventure! :)

@MastaKeahi Жыл бұрын

I wanted to reach out to you because I always do lol. I finally got my bike back together and I’m having carb issues if I take my air box off and put tape over the back of my carb on the opening that goes up to the diaphragm my bike starts I cleaned the carbs and bench sunk it. I really don’t feel like doing it again. Should I just rebuild the carbs totally?

@UrbanMonkTV Жыл бұрын

Have you cleaned them once already?

@MastaKeahi Жыл бұрын

Yeah I even cleaned out the pilot gets I think I used a a B or e string to clean it out haha. I’m wondering if It’s a diaphragm issue or if I’m just not getting enough gas?

@UrbanMonkTV Жыл бұрын

@@MastaKeahi Assume from you comment that your have CV carbs. If sliders are stuck it Shouldn't affect starting too much. I'm guessing you have a fuel or air or both line clogged in it circuit. I forget, did you ultrasonic clean the bodies?

@MastaKeahi Жыл бұрын

@@UrbanMonkTV no I don’t have the ability to do that

@UrbanMonkTV Жыл бұрын

@@MastaKeahi You may need to pull them off again again and use carb cleaner in all those passageways at least. It's difficult for me to know exactly what you're dealing with from here but a no start (with all else working good) is usually a clogged idle circuit.
