Excellent video monk will be a great help on my build . Really appreciate it
Thank you for watching!
Hello (jean-marie in France), Concerning the adjustment of the anti-pollution screw at 5 minutes 30 seconds of your video, it is indicated in the technical reviews that this screw is factory-set and not to touch it. changed all of them and I don't have the settings, you saved my life by mentioning the 2-turn setting ..
I have not yet reassembled, I am waiting for the delivery of the intake pipes ...

Merci for watching! I'm happy my video was helpful.
Thanks! Been thirty years and I damn well couldnt remember how the jets went! Great video!
Building one for my son. Pissed my wife off but you cant ignore the call!
Thanks for watching!
@@UrbanMonkTV Us "old" motorcyle hounds have to stick together. We're disappearing too damn fast as it is!
@@rockyborn_on_flag_day3832 Right on! And my mother's bday was flag day! :)
When you take out the pilot jets (size 50, next to the main jet), there should be another, smaller jet mounted in the same recess, behind it. This would also need to be removed for cleaning.
That is correct. Thank you for watching.
I am having difficulty finding carb parts for my 79 GS550. O-ring kit, float valves and jets. Can you please post your source and part numbers? Very well done videos. Big fan.
Thanks for watching. Your 79 will have different carbs than mine (assuming you're in the U.S.). Slide carbs in 78, CVs in 79. So my part numbers won't help you. I had good luck with cruzinimage.net, Jets-R-Us and eBay.
I know I’m very late to the video. But I’m just wondering is it just the carb shoes that hold the carbs in place. I’ve inherited an 81 that has been disassembled without any regard towards labelling for the rebuild. Lucky me.
I have been binge watching your videos tho and they are an amazing encyclopaedia of knowledge on the 550.
Thanks for watching! The carbs are held in place by the insulators on both sides (airbox and intakes to cylinder head), but when air box is removed for pod filters then only from insulators hold them. They are capable of that though.
@@UrbanMonkTV thanks for the reply. That’s good news so. I’m not missing as many parts as I thought. He stripped the frame and threw everything into a bucket every nut and bolt just thrown lose. And then dumped all the brake parts. You’ll get plenty of views from me trying to piece it back together. Thanks for the great quality content 👌🏻
@@Rebius1 If you find you've got a bunch of bolts and nuts and don't know exactly where they go, I often use the parts diagrams on suzukipartshouse.com to find location and size. The item description will say something like "Bolt A 8x120" followed by a part number. That would be an 8mm diameter bolt 120mm long. A cheap machinists caliper will help you determine which goes where in a hurry. Hope that helps!
@@UrbanMonkTV yes. That’s super helpful thank you 🙏
Top job
Hi! I love your videos! On my carbs the fuel screw was screwed in tight in all carbs. Do you know how to adjust these? My manual just say dont touch this screw😅
Thanks for watching! I would start with all them two full turns out from fully seated. Then adjust each from there as need to achieve a good mixture at idle. Remember they only affect idle. Getting the right mixture is easier with a colortune, but you can also check spark plug color to see how it's burning.
I never would have learned this if I wasn't reading comments. Thank you! @@UrbanMonkTV
@@lindsayspates8907 Thanks for watching. And reading!
For the float height my clymer manual says 26mm without gasket and 25mm with.
It's been so long since I built Mr. Kortan I don't recall the details. But that sounds about right.
Rocket Surgery 🤣 youre the best
So after you preset your fuel screws at 2.5 turns out how did that run on the bike? Did you find yourself adjusting further?
It runs good at that setting but I did need to adjust air screws further during carb syncing. Bike runs really good now but is difficult to start cold. Gets too much air. I choke it further by squishing the Uni-Filters. Works good. Thanks for watching!
@@UrbanMonkTV thank you!
You might want to consider using K&N Filter oil, but would check to make sure it won't eat the faon material on your filters.
I reckon we are both at the same point in our builds, ive shot footage for the Carbs 😂mind you ive just had to change fuel rail O rings as they had pretty much had it.
Yours had orings?! Mine are rubber and plastic moulded together. Maybe a difference in markets? Or perhaps year and model? Question...Are you attending the Bike Shed Show in May by chance?
@@UrbanMonkTV Aluminium sections with replaceable O rings, must be a year or model difference or maybe an aftermarket fitment. Its great to hear about how these models differ. Yes will be attending Bike Shed and will be filming for the the channel
@@dtaylo4517 I'm considering flying in to do the same! Would be great to connect if I do.
Urban Monk TV Really?!?! thats dedication 👍yer that would be great. I can see the title now, UK GS meets US GS 😀
@@dtaylo4517 Would be great! We'll see if everything falls into place for me.
Did you have to rejet the carbs since you used the pod filters ? I’m having a heck of a time getting mine tuned right.
Yes. I went with 95s mains. All else remained the same except fuel and air screw settings on idle circuit. Hope that helps.
Urban Monk TV where did you pick those up ?
@@OutdoorsmansParadise I got a whole set (75-125, X4) on eBay for cheap. Otherwise, jets-r-us or cruzinimage.net.
I'm not sure how you attached those hoses but just zip ties they're black like the frame and it will be under the seat
Thanks for reminding me I need to order some hose. Misplaced original. 👍🙂
sorry I keep posting more comments instead of just one but my carbs look completely different then yours. as I said an '81 but you have to hook up the throttle cable and choke cable before you set the carbs into place. but your's has I'm gonna call it a stack on top like a chimney I don't have that at all. when I say completely different even the internals is different. nothing looks the same. maybe they figured something out in 3 years lol IDK but anyway thanks for the video
You said that the one part was the air screw but I think it’s the fuel screw I think the air screw on carbs that have then instead of a fuel screw, anyway I believe the air screw is flat not tapered. Anyway doesn’t really matter but I don’t understand why it has a spring your screwing it it’s not going to have spring. Btw I have an 81 gs550e I got it on a trade with ‘88 plates on it. If that tells you anything
Thanks for watching! Yes. I correct myself at one point in the video. I've restored a Honda CB900 that sat without running for 7 years and it ran fine after cleaning up the carbs and brakes. These engines don't seem to mind much. 🙂
@@UrbanMonkTV I just got to the point where you corrected yourself. I did get it started but its running lean but I didn't adjust anything I cleaned everything and put it back as was I wanted to get it started before spending too much time tweaking.
@@skidz8426 Always fun to hear that first start after spending time working on it. 👍🙂
well I traded the bikes for 3 pottery classes and my wife had doubts said I was starting a junk collection. when I started it she was like ok I know your happy. funny think I went out the next day took the carbs off calibrated them put them back on bike wouldn't start. just a clicking noise. hmmmm starter went bad??? started to take the starter off and thought let me check the fuse yep fuse burnt up probably sitting so long then activated it and it didn't like it.
