Suzuki gs500f, 2007, wierd sound in idle
I have attached a video of the weird sound my motorbike makes. The sound first appeared after we pulled the carbs out to clean them.
whenever the sound comes, the revs dip down a bit, and then come back up. the sound seems only to be present at around 2000rpms, and is never present much higher than that. it also seems to get worse, the warmer my bike gets.
I have tried looking for a vacuum leak, but I don't seem to be able to find a leak when I do a test.
I did a carb sync also, but it has not removed the sound either. for info, the bike is a Suzuki gs500
I would really love some help, as i have almost pulled out all my hairs on the top of my head.
Kind regards, someone who wants to ride with his friends and not be an amateur mechanic any longer.
