i was wondering if anyone knew the right way to adjust an S&S carb on a 1980 1000cc bike. i tryed messing with it and it idles a little lower now but in first and second i have to play with the throttle because the bike starts bogging down. wide open the bikeis fine but once i back off the throttle it bogs down. any help would be appreciated. thanks

 

Is the bogging down something that just started, or has it always ran that way? If it just started happening, I'd start off with a good carb cleaning to insure all jet passages are clean and flowing properly. Also check the float level, a low float level can cause unstable flow between idle and 1/2 throttle when the main jet starts to kick in. I don't have s&s, so I don't know any specifics for adjustments, but in general most carbs use a fairly simular tuning procedure, wether it's mikuni, keihin, bendix, s&s. the mikuni carbs have a pretty decent tuning guide on their website, not sure if s&s offers anything, but you could try e-mailing them, i've heard their costumer support is pretty decent.

 

thanks i will try emailing them. the bike has done this a little for a while but just recently it has gotten alot worse
