I posted a carb question here a few weeks ago in regards to a stuck float.
I took 'em apart and sure as shit found the stuck float.
After cleaning the carbs I cranked the bike and now a new problem.
It runs at low RPMs. like the choke is stuck on, kinda bogging down.It's sorta like when you run low on fuel & have to change over to the reserve.
Once it' opened up and you get moving the bike really takes off.
Maybe gettin' too much fuel??
Everything in the carbs was cleaned and put back together correct.
Is there a chance one of the jet needle e-rings got pushed down when the tops were being put back on????

Anyone got an idea??
A carb sync??

When you tore them down I'm sure you did a good job running air through the passage ways...but did you put any new parts into the carbs? Seals? Needles?

No.
I just cleaned all the floats w/ carb cleaner.
I also took all the diaphrams out & cleaned the tops of the carbs/jets out.
Then put 'em all back together the same way they were.

I just came back from a short ride & it's gotta be gettin too much fuel.
At low throttle it runs kinda boggy, then when you open it up everything smooths out.
Then when slowing using the gears it kinda rumbles again where it was smooth.
Also got a real strong fuel smell like it's flooded.

I did notice the petcock was developing a tiny leak.

oh well, too late now. It would have been good to check for any wear on the moving internals. Certain years of carbs have a reputation for the emulsion tube seat getting worn. or it could be something else. I'm no good at diagnosing carbs. I prefer to tear them totally down and refresh them before hooking the bike up to a dyno for proper jetting.

It's also pretty easy to eff up the float-height ...did you check that while you had it apart? synch and check the fuel-air screws, and if that ain't it, pull em back out and check the float-level. just a mm or two will make a huge diff.

Everybody is on the right track. Another thing to look at is the o-rings on the floats themselves. Did the floats push in easy or was there drag on the o-rings? I also like to set the float level between 14.6 & 15.6mm. If it's below 14.6 it won't run right.

Thanks for the input...

I'll do some checking next weekend & hit you guys/gals back.

I'm thinking the jets myself.
After the sync I'll know for sure.

You guys R the best.

Let me be the first to say HAPPY HOILDAYS to the best friends one could find all over the globe sitting in my den.

Peace.

You know Cat..you might be right.
But what would explain the heavy fuel smell?
It really seems like it's running rich. I think this because it evens out when the throttle is opened up.
Also, I went thru a set of coils last year & the bike would shut run shitty for a few seconds then shut down.
But, I replaced 'em with stock zookie ones.
I know, I know..WTF was I thinking.
Live & learn. I put about 15k on the new ones.

Anywho, thanx for the input & keep up the good work.

The O-rings on my float bodies were wasted....I will replace this week.....

I have a metric dial caliper to use for setting the float height.........just rest it on the carb body and eye it up?

Is this the correct way?
