  • DT25C SUZUKI rough idle and sneezing

    i have a 1996 model suzuki dt25c that starts fine cold but after normal operation it becomes hard to start and then will not idle smoothly before sneezing then stalling.have had carbs cleaned and replaced all fittings,checked throttle sensor,also it seems to be blowing more smoke then before.goes fine wot but somtimes stalls when backing throttle right to idle to start trolling!

    sounds like a lean sneeze to me. look closly for any air leaks and on the suzukis you turn the screws in to make it richer instead of out like the rest of the world. the oil is injected aft of the carbs so even if the pump was misadjusted a bit it wont affect fuel delivery, float setting will though.the throttle switch controls ign advance and wont make it sneeze. that sneeze is actually an explosion on the wrong side of the piston due to a lean air/fuel mixture in the crankcase.
    no tech questions by PM, they wont get answered.
    you have to be trusted by the people that you lie to .
