Running rich?
After doing forum research I think my bike is running rich. However, it doesn't seem quite right, it's like a mix of too rich or too lean? I've listed symptoms as well as I can.
Has to have almost max choke on to start: lean? Smells really gassy at idle with choke off: rich? Engine dies unless RPMs kept above 3.5k for the first 5 minutes of riding: normal? RPMs drop to almost nothing, then slowly drift up to 1200: rich? Engine bogs below 5.5k until very warmed up, with and without choke: rich? Really poor gas mileage, partially from choke duration: rich? Runs way better when warm: lean? Can take almost full throttle within 10s of starting, with no choke: rich? Sometimes stalls after getting off freeway from a 10m ride: rich? What steps do I take to confirm or fix the problem? I think looking at the spark plugs is the simplest? |

Cleaning the carbs is in your future... I feel.

Ah, my bike did sit for about a month while I looked for a new engine. Seafoam is in my immediate future I think. Totally forgot about carbs.
Stock everything except cosmetic. Thank you for the responses |

Also consider Star Tron fuel treatment. Be sure to increase your idle speed as well if the outside temps have dropped.
