no vacuum hoses/lines on carbs

[Daniel88bishop]

how bad does this affect my idle problem..? it either high revs or dies, and I can't find that sweet spot inbetween . I've rebuilt the carbs and replaced all gaskets and don't kno if it has 2 do with it missing the vacuum hoses/lines.i bought the bike this way and already fixed/replaced everything else but don't kno what 2 do now cuz of the idle problem..is the missing vacuum stuff all that's wrong..?

Vacuum caps for carbs 1,2,3 and vac hose from 4 to back of petcock. That's a start.

i put the new hose on the side of carb 2 the remaining peticock . it's wanting 2 idle but still will hold a high Rev and slowly come back down 2 a bog,then die again..do I need 2 remove the cap from #4 and put the hose there or leave the hose on the side..?

What year is it?.

4 sync caps,1 on each diaphragm cap. vac port on the side of carb 4. Which leads to the back of the petcock. Did you sync the carbs yet?

[Daniel88bishop]

yes,they synch'ed.

Are all four cylinders firing? You can check by measuring the header pipes. truely, I think you need to reservice the carbs and check everything, float heights, emulsion tubes (o not 0) reclean them with a carb dip.

I guess I should have asked if it was a pre or post..lol

[Daniel88bishop]

how many carb adjustments is there..? I kno of course the warm idle adjustment,is there a cold idle adjustment other than using the choke..? and yes all 4 cylinders are firing..!

[arsenic]

how many carb adjustments is there..?

More than you're doing

[shpielers]

You can adjust how synced the carbs are to each other, the A/F needles can be adjusted, the float height can be adjusted, needle position can be adjusted with a jet kit, idle and choke can be adjusted as you already seem to know.
