| My ST4 was idling low in hot weather here and sometimes stalling in traffic. Took it to the dealer and he was going to adjust the idle, but instead he shot carb cleaner into the air intakes and also used some carb conditioner (foam) to clean them off. I got an instant 200 rpm increase on idle. he said that slow speed running can build carbon up near the air intakes of the injector and that is what slowed the idle down. COuld this be similar to what is happening to you? |
