Bike 87' zl 600
rode bike in rain, before the cold weather set in,FL. I been trying to get the bike to a least idle with out the coke. I have tried to use starting fluid on it sparinly, it will race when i spray carbs 1,2 it will bog out when i spray 3,4.
done all the things before this, checked plugs,wires, changed gas, drained bowls. I thinking it might be valves. If any of you out there got other ideas, let them fly,want to go to daytona with it this year. thanks for your help.

 

Start with draining the bowls and inspect what comes out of the bowls, such as water or debris. You may get lucky by adding some fresh gas and an additive to clear up the slow speed circuit. Good luck
