motor bogging under load
I dipped em cleaned diassembled everything without unsyncing .......seems like they are overfueled sometimes. Once the carbs get warm it seems to go away. Also bike needs lots of choke on cold starts. I hear this is indicative of the 1100's though. Sometimes I pin the throttle and its like I'm on a hill in high gear and other times it just rips to redline. Any experienses similar would be appreciated. Searched for 30 minutes this morning but there is so much info on the site I get side tracked with other peoples interesting gremlins.Tags: None

from bakersfield?
A friend helped me....took everything out.....jets and what not sprayed with cleaner ran wire through sprayed, dipped anything non plastic.
The hard rubber plugs were in bad shape due to po bone head.....could they be the culprit?......what is it exactly they do? The plugs that sit in the bowls that is

K its impossible to dip the carbs (THE WHOLE CARB BODY NEEDS TO BE DIPPED ALONG WITH THE BOWL) without "unsyncing" them, unless you left them together, and then youd have other problems. All of the Orings need replaced as well. The rubber plugs, if they dont fit back in the pilot jet shaft as they should TIGHTLY, will leak, and you will be feeding fuel to the pilot jet unmetered. Your float levels need to be reset as well. "Lean starting" is not indicitive of "1100s" that have had the routine maintenence done. Did you also check your slide diaphrams for pinholes?? Holes in the rubber diaphram will cause the slide to leak and not lift, or not lift as fast as it should etc...

ok
Now we are talking!
You actually know about carbs....all 4 carbs were spotless with new parts but the po put some sort of preservant in only 2 that messed up the plugs. They looked to be sealing well but I'm not 100% would that explain the bogging? It starts ok on full choke but takes like 5 minutes to idle well with no choke and once off choke if I twist it up it just bogs

D.T.
I'm having the same issue. Between 2-3.5k rpm.
Idles very nicely and rips above 4000 rpm. 1980 850, all stock.
Pilot mixture screw, will this help get rid of the bog? I think they were around 3 turns out. Will turning it OUT make it richer or leaner? Air screw or fuel screw (the top screw right before it goes into the intake boot)?Last edited by Guest; 07-11-2010, 03:34 PM.
