On my 81 xs400 special, I have 2 factory mikuni carbs. Thing is, it was running rich but still managed to score the plugs as if it were lean and rich. Cruising speed was a no problem. But anything over 35-40mph at around 1/8 to 3/4 throttle seemed like the bike had to catch it's breath before taking off. Mains are at 142.5
And the jet needle is a Y316S set at the middle position. How do I tune these jets to make my bike do 60 at least without bogging down?
Will post pics later. I'm stumped on what to do so any and all help, helps! Lol thanks guys
