What did you do with the throttle linkage, did you use the standard cable? Also what changes did you make to jet sizes. I'm very interested in this as our d15b4 in Australia are auto choke and it's hard to find a replacement choke to fix poor idle issues and running rich. If you have a forum write up about it I would be very interested.
Thanks! The car is having a rest since 2021, but I will make it run again for sure. I didn’t really think about the fuel consumption while it was in, but it was higher for sure…
do you have an AFR gauge? I notice on moderate throttle, for example passing someone in local traffic (not wide open throttle) I see it go rich for a second (AFR 8).
@@bozidarbilusic at DanST website they have 30mm, 50mm, or 90mm long trumpets. What do you think that fits? Can you tell me how much space until the firewall after the carburettors? Thanks!
Hi man, thanks for the input. Seen your video, it’s looking nice. I used original pilot jets (42) and 150main jets. At first I used original main jets as well;132-135-135-132, and it was also ok, just a bit lean at wot
Brate Bozidare pa ja tebe trazim :). Molim te za pomosh. Imam D14a1 Dual carb. Problem, obrtaj mi ne stoi na hladni motor, pada, ako ga shtimam ondak na vruci motor idi do 1200. Zapushio sam sve vakum rupe, dobar mi je bubanj za kochenje, novi dightung na usisnu, nashtimao ventile, nashtelovo i paljenje. Desni vakum port je advance, to jest retard, a ljevi plus 4 stupnjeva za hladno paljenje. Zajebavam se veche godinu dana, jel moguche da me jebe kaish za jedan zub??? Ili pak mozda ono shto nemogu da vidim, karike, dihtun na glavi ili gumice ventila!?. Znachi opet chu da ponovim, valjda nemam dovoljno vakum na hladnok motora? Ili mozda neshto drugo.... Hvala unapred, pozdrav is Skoplja.
Ja bi prvo probao start sprejom po prirubnicama karburatora, one uglavnom stvaraju ovakav problem. A usput i sva druga vakum crijeva, ako imaš ona s brojevima, originalna, lako je moguće da puštaju. Mogu biti i membranice od power ventila na dnu karburatora, vidi ima li goriva u crijevima koja idu do njih (#14 ako se dobro sjećam). Probaj skinit filter zraka pa vidi kako radi bez njega

I'm currently doing this project on my D15b4, with a 94 Cbr 900rr carbs
Wish me luck 🙏
4 900cc carbs or Carbs off one 900cc Bike?
How did it go?
@pummarinmuidaeng8395
Havnt got it running mint yet, wish I went Mikuni 36m carbs instead
Thanks man!! Will be looking more into this.
lifesaverrr, thankyou so much!
Amazing stuff ! Thank you!
Thank you

Where are you based Eb240, I'm just outside of brissy and currently doing this build also
@@AgentOfMadnes im in NSW blue mountains
Should add on socials, and share our builds ?
@@AgentOfMadnesI know this is a really old comment. But curious if you ever went through with this.
@@EB240did you end up doing this?
Awesome! Is your setup still going well? How is your fuel consumption?
Thanks! The car is having a rest since 2021, but I will make it run again for sure. I didn’t really think about the fuel consumption while it was in, but it was higher for sure…

No, I didn’t use it on this project. However, it’s very good thing to have. I relied on spark plug colors and the sound mostly
Thanks
nice🎉
Hello. I was wondering on ordering a kit from DanST, do you think the 90mm trumpets fit on the same car and engine as yours?
Hi, There’s no much space there, so unlikely
@@bozidarbilusic at DanST website they have 30mm, 50mm, or 90mm long trumpets. What do you think that fits? Can you tell me how much space until the firewall after the carburettors? Thanks!
What is the ignition time advance after you get 4 carbs?
It’s the same as it ever was, I kept the original distributor with vacuum advance
Can this be done to a d16y7 motor
It can, but not as simple as with factory carburated engine such as the ones mentioned here.
Do you have the K&N filter part number??
This foam filter? It’s pipercross, off some old BMW 5. Dont know the part number, it was a large tube of faom, and I just cut a small piece I needed
How can carbs off a 600cc give enough gas for a 1500cc engine?
That’s a good question. However, the problem is how to limit them to giving just enough
Because a 600cc engine revs twice the speed of that 1500cc engine
So they have more or less the same airflow
Brat, snimi sound video.
Hi what size main jets did you use on your car
I used
0.50 idle jet
150 Main and
Moved needle up three spaces...
I think my needle was set to high.
Check my video out of my one
