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

Thanks for the shout out mate

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.

hi I've been fixing bikes since I was a kid and I've took the leap to fix bigger more powerful bikes and to be honest very detailed and easy steps and the carburettor synchronize kit I have a works great thanks to your other video and I am in the process of doing my carbs on a Yamaha XJ600N hope to see more as I'm happy with everything you state and describe with easy to follow instructions keep it up I'm now a subscriber thanks again regards Julian

Great info!! Few things I would have ever known w/o this particular video! My gs550 has a lot of the same issues! Guess I'll be buying a carb synch next! Thnx UM!!!

Thank you very much for your GS550 videos! I really appreciate this.

Thank you very much. For the knowledge. Thailand...

Hi there, it was a great idea to use IR thermometer, would try on my XJR 1300, since i don't have a CO tester. Thanks

A lot of great info to synchronize my GL500. Thanks a lot :)

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.

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

Where do I find the follow-up to Part 102? How did you address the carb not delivering fuel?

Thanks sir ❤

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

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

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

Going through the same deal on my Kawasaki Voyager 1200 now.

What was your final jet sizes and what were they stock

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?

what did your issue with the dead cylinder end up being?

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

Just because your building a cafe racer doesn't mean you have an excuse to look like a beatnik, get a haicut kid! (Lol).
