Hi guys I didnt mess with the throttle position sensor but someone has. This bike has been modded a bit but ran half ok before I cleaned the carbs it is now so rich I had to turn off the fuel when I took it for a ride to clear out then turn it back on. I have checked the two diaphrams countless times and the little diaphram around 5 times they all seem sitting well and seated.Needles are home and retained by the plastic holder. Where is the little filter as described and thanks for assistance from you all.
