- Watching another channel last week I thought "That might be my problem too!" so I take another attempt to sort carbs, then go for a short test ride.

Been loving your journey with the Super Dream. I’ve binge-watched, from the start when it was in parts, for the past 4 days. Well done.
Thank you for your feedback,, much appreciated. Ryan.
For future reference, a bolt has a plain shank, as you have there. If you want them fully threaded, you ask for set screws.
Thank you. I didn't know that.
Great to see you out on the Superdream looks like it’s running better too , Happy Days 🤟
Thank you. It is. 👍🏻
Buy the smallest hoop , cut in the middle of the bend , insert a small dowl and weld back up and grind back , that you can do with out a bender , also recommend buying the largest ultrasonic cleaner you can afford , will pay for itself in no time
Good advice, thank you.
Great job, remember it's a 40 year old bike having no more than 27 HP, it sounds like it's running smoothly 😊
Thanks KI, itis certainly running the best I have had so far. Still feels its holding back a little, but maybe that is because i ride modern bikes.
Well done with the carbs Ryan👍
Thanks Derek.
Ryan have a look at the 1971 Norton Commando 750SS it has the sort of exhaust system you are interested in with the heat shields. Look how low it is, and please note this model only lasted for a year as it was not popular, and I believe it may have been the hot exhaust pipes that prevented its popularity. All the best John
Thanks, i will try to find an image of one.
I ve done same rebuid on a SD250N around same time. Followed your build as well. I only got the point of even running and tickover when i softened the inlet and airbox rubbers so i had a better seal and no air leaks. I have also fitted twin silencers and collector box as original set up, as i had the Motad 2 into 1 like yours. I'm sure that also makes it run and idle better, but I could be imaging it
😊
Well done David. Hope you will get it riding sometime soon.
I've followed Flint's build from day 1 with it all in boxes - you are now getting what you deserve for all those hours of the build - thoroughly deserved!
Thank you Tim, I appreciate that.
Im glad the carbs are improving on the cb. As for the scrambler exhaust, you can put it anywhere you like. It's your bike. Have fun brother. 👍❤️✌️
Thank you, once again. 👍🏻
Hi Ryan many moons ago I had a CB400N it wasn’t the fastest of bikes even then when 2 up you struggled to do 70mph without dropping down through the box BTW love your videos they are interesting and knowledgeable keep them up
Rich ( Richards home mechanics )
Thanks Rich, Mine is only the smaller 250cc, so I don't feel that getting it near 70mph is far off as much as I can expect.
Great bike for sure 🤟
Cheers Paul, I am pretty happy with it now. Thanks
Well done. It all takes time 👍👍👍
Thanks, it certainly does.
Hi Ryan, Another useful video as usual and the bit on the air passage for the carbs was something i wasn't aware of but i am now and will look to do now that im close to finishing my 1982 Super Dream build. Have you considered putting the pipe the other side with a 2 into 1 system and using a short tail pipe low down rather than up high? Appreciate your trying to keep the pipe up for ground clearance but i suspect you will have to have something bespoke made in order to achieve that and the radius might restrict the exhaust gasses. just food for thought.
Hi Neil, thank you. Your exhaust suggestion is not a bad idea, just not what i am aiming for. Although maybe my abilities will ultimately limit my options.
I really feel your pain with those carbs . I have had so many issues with the single CV carb on my 250 Rebel . Had it on and off about 10 times before I was happy with it . Can't imagine the stress involved with two of them . Well done . Hope yours is ok now . Carbs can be a real pain .
Thank you, it seems so simple, but then feels like a black art when they don't cooperate.
Not that I have a lot of mechanical knowledge. But won’t the heat from that exhaust affect the fueling to the carb closest to it?
Hi Donald, I guess it could yes if the exhaust was too close the to carb. I am hoping that with an exhaust wrap and it should be okay.
Are you running the CB250N on E10 or E5 petrol.
Hi Jon, I am only running E5 on this bike, I am no expert but I understand that E10 can cause damage to some of the Carbs internals.
