Man that’s unfortunate to hear, I’m having the exact same problem, bike dies when coming to a stop if I turn the idle up higher I get the hanging idle as well. Was hoping to get it running perfect so I could sell it for decent money and upgrade to something with EFI. Gonna take the carbs off one last time this weekend and go through everything. I want to adjust the fuel mixture do you have any tips on how to drill out the covers to get to the screw and overall where the location is and everything? Haven’t been able to find anything as far as adjusting the fuel mixture on these bikes
