now after cleaning all the vents for the gas cap, rechecking the ground on the battery (still no throttle acceleration) I am going to completely empty the tank, clean her out and get her ready for some total fresh petrol, and c where we end up then off to the carbs and jets. thx for the replies, very much appreciate the time.
here is a mechanic 101 question, why does the bike idle so dang smooth either full choke, half, or closed choke, but the acceleration is unobtainable and the bike dies? why does the idle not keep the bike running even if I pull the throttle?
There are usually three jets, or metering systems in carburetors. It appears that your idle jets are clear, but remember that idling uses very little fuel. The pilot and main jets are the critical areas where the real flow is. When you open your throttle beyond idle, the air/fuel ratio changes to mostly air, starving the engine of the ratio it needs to run. Quit wasting your time and take care of the carburetors that sat neglected for a year!
Once you drop the bowls, you'll see the mess inside. Gummy gas, water, and the chemical reaction between the water and the various metal parts in the carbs create real havoc. Take the carbs off. Take them apart. Remove the jets. Clean them with carburetor cleaner and blow out with compressed air. Look through the jets with a strong magnifier to determine if the holes in the jets look clear and round
. Don't try to run any drill bits, wires, etc. through the jets. The most I will do is to take one strand from finely stranded copper
wire, and very gently try to clear a jet hole.
Get a manual and follow it for the reassembly and float adjustment.
