Hey Folks, so.. I’ve replaced the shims, throttle cable and stripped and lined the tank on my Yamaha fzx250 zeal. When I start the bike with the choke out fully it isles at around 4K, when I bring the choke back halfway revs go back to around 1600. As soon as I give it any throttle or push in the choke the engine cuts out (It was doing this before I replaced the shims and other parts). I’m assuming the carbs need balancing? Is there anything else I should be looking or listening for?
