hello i just bought a 81 kz 550 and am a new rider.the problem i have is trying to get bike running when cold.it will start right up when choked.the rpm go upto around 4000 then settle down.if i take the choke off it will stall right away also when i give it gas it will stall.after a while it is like hitting a switch it will run fine and idle fine without the choke.but if it sits an hour it is hard to start again.once it is warm it runs great.not sure what to try i have replaced the plugs and ran some seafoam thru in the gas.any advice would be much help.
