Everything sounds good, thing that bothers me is the "unhooked" air box. Running without airbox and stock pipes is like having pods. You will be running way lean (especially with 97.5's) Are the carb to box connectors missing? When you remove carbs and look down air box side of carbs, does accelerator pump squirt fuel into each carb when linkage turned? Pump was installed to compensate for lean jetting for better throttle response. With factory lean jetting and no air box you may have a very lean condition!

mains are for racing could they and the air box be why it dies when you hit the throttle ? I just want to ride in city driving so what main's should I use and well I have to change the needle's too? Also I'm assuming they are vm
28's.kawasaki made carbs with just a Air screw and one with Air
screw and pilot screw how can I know for sure these are not missing pilot screws? Lance

Thank you for all the good words,the air box,s is unhooked because of trying to get the bike to run. I see that 97.5

The 97.5's would be the stock (not racing) jet size for a '80 F1. Sounds like you have a stock set of VM24's. If they are the factory carbs they will have the "air" screw on the side of the carbs at about a 45* angle. Two turns out is a good starting point. A pilot screw would come straight up from the bottom by the fuel bowel. My F1 has a spot under carbs where pilot screw "used" to be.
If carb parts are clean, sounds like you have a fuel starvation problem. Make sure fuel flows freely from tank, how are float bowel levels? Too low will cause major lean condition.
