Street fighter/ Bobber build 2.0

Help fuel spitting out the back of all 4 carbs. Spraying out the hole in the 10 o'clock position. It started spitting fuel on last jet change. So i took apart the carbs again and blew out all the openings all were fine no blockages. Decided to raise the floats to 26.2 from 25.7 on 1979 carbs. Reinstalled and problem still exists....could use some help. I've removed the carbs a bunch of times and never had a problem after reinstall.

I hear you on those pods...
Ok pods on and air screw out 1/2 turn improved response but not that good still loading up. I'm going to step down to 42.5 pilot and see what happens first.

Then the pods may just not flow the air you need. Look at the surface area of the pods, and see if there are some with a little more area. I seem to remember XS650 had some that were oval...

Sorry a while ago before i started with carb tuning.

[Fearthepack]

I did the stock air stacks modification to the pods so that should have eliminated any lip interference.

[DiverRay]

+1 on the pods being the problem! Look at the inside of the pods. If there is a smaller diameter within 15mm of the outside of the lip, there is restrictions at the air jet. If you still have the harden rubber from the stock airbox, cut them to about 1.5" long and mount them on the carbs first, then mount the pods to those.

Maybe the rubber on the pod is restricting the main air jet in the carb bell. If not, I would try a different style of pods that are more free flowing.

.....tried larger mains 147.2 and 150 to no avail what next. I put the 145's back in which should be correct with my setup. This time i left the pods off and it ran like a bat out of hell...WOW finally got to experience big pulling power. So no pods with unrestricted air flow leaned out the excessive rich condition causing my poor running issues. I think my 145 mains are correct because strong constant pull to redline. I had to stop at this point ran out of time.
So when i resume i'm planning on working on the correct pilot size which is one up from stock 42.5 to 45. With pods back on I will screw the air screw in from 2.5 turns out to lean out conditions. If it corrects running conditions from 1.5 to 2.5 out pilot is good. If I hit 1.0 or less the pilot is to big and needs to be switched back to stock 42.5. Can I get a yes or no on the direction I intend to go before I start. Thanks in advance. Carbs are confirmed earlier 79's.

[Fearthepack]

Was hoping to get the carbs dialed in today looks like a no go. Stock engine with pods and 4 into 1 with a small muffler.... looks like the 145 main is to small doesn't pull well at upper rpm's. Also have 45 pilots it pulls well from 2-6000 rpms so appears that is correct. No use going any farther until I get the mains right. I'll order 147.5 and 150 mains.

To be safe, you could put a hose to a "Y" fitting between them, and put a paper fuel filter over the third end of the "Y" to keep the critters out.

[Fearthepack]

Thats what i was thinking thanks....

[bikerphil]

Leave them open as they are bowl vents. Capping them will result in a flooding condition.

[Fearthepack]

I'm using modified pods on the carbs so what should be done with the carb tubes that would have run to the stock air box. They are just above the fuel intake connectors. Nothing or do they need capped? hope i explained that good enough...

[xs11lover]

Pretty cool!

[Fearthepack]

Back in the saddle again....LIFE is what happens to keep you from completing projects sad put true...I got the bike out of storage again and onto build 3.0.
Took the carbs apart very clean still, did find a clog in the float bowl vent of number 2 carb.... reset all the float levels they were way rich which should explain the sooty black plugs. Fired right up but wow the belching of raw gas out the tailpipe so rich. I'm running pods and 4 into 1 with small barely a muffler. took the carbs back apart and finally, finally, finally, finally found I was missing the 4 large screw plugs at the bottom of each pilot jet stack. I can only imagine how much gas was being sucked up the through the pilot jet. Installed the missing screws,Started back up and what a difference, no visible signs or smell out the tailpipe. Now onto dialing it in with sync gauges. Small battle won. Hurrah Looks like time off gave me usable wisdom.
