Hello, I am kinda new here so please bare with me. I have a problem with my 80 yamaha xs400 mikuni carbs i believe its the carbs ??? the bike is sluggish in the idle to taking off stage or idle to 1/4 throttle also on the right carb according to the plug it is runnning rich now the pilot adjustment is at the factory settings and i believe it is 1 1/4 out (bottomed then 1 1/4 out) still rich real rich im guessing this is why the bike is a little sluggish in the starting off stage it seems to run good in mid throttle range and upper throttle range no new exhaust the only thing different is pod filters???maybe this not sure , also from the look on the plugs it appears the plugs are running cold from the looks from the plug ground tip only sparking not at least half of it so carb r clean should i go with maybe a smaller pilot jet??? sorry for all the babble just want everyone to know the facts Thanks for reading Eric From Burlington Iowa
