Motorcycle Repair: 1982 Suzuki Gs550L engine problem, 1982 suzuki gs550l, mikunis


Question
hmmmm, well, im not exactly sure for 100% but id say it starts bogging at 1/2 maybe a lil more, ok if this helps as well, if i maybe use about 1/3 of the throttle it'll climb up to the mentioned rpms no problem, but then if i try to just wind it out full throttle, it just about stalls, my brother in law had taken the carbs apart and soaked them in carb cleaner, maybe he didnt put them back together right? or didnt clean well enough?

ok last question (and this is gonna sound dumb...on the mikunis which one is the are mixture? i have a repair manual, but it doesnt show where they are and says not to mess with them, it idles fine, starts right up, but just doesnt like opening up the throttle up

thanx again
john

Answer
John,

The air-fuel screws are located on top of the carbs and to the rear of the carb caps (diaphragms).

You may have the infamous Suzuki charging system problems causing your improper running problems. Take a peek at this site and consider performing their electrical tests.
