Have you checked for a spark? or done a compression test? You may need to adjust the idle screw or tick over screw slightly 1/4 turn at a time (remember where you started.)

Could be heaps of things.

Check clean fuel is getting to carb.
Check air intake is actually "sucking" air.

Call a Honda dealer with the frame number on the bike. They should be able to tell you where the bike was manufactured. The valve settings should be the same no matter where the bike was made. There is a proper way to start the engine. Four controls are on your bike to assist in starting. Below are generic instructions.
  • The choke, used when the engine is cold. Pull the red knob for choke.
  • The " Hot Start " Lever, used when the engine is hot. Pull the lever to lean the fuel mix when the engine has been running.
  • The de-compression lever, always used.
  • The throttle, used to prime the cylinder, (power valve).
Don't kick, instead, push the kick lever downward. You will feel the back pressure as the piston is going upward on the compression stroke to the point the pressure is great enough that the kick lever "locks up". You are very close to TDC. NOW, pull in the de-compression lever. Push the kick lever a little bit more to get the piston past TDC. Now release the de-compression lever. Give the throttle a 1/4 turn then let it snap closed. A diaphragm, (Power valve), in the carb gives a shot of gas when this is done. DO NOT do this multiple times because you will flood the engine. Leave the throttle closed when kicking. A flooded engine will often backfire. Now give a strong kick through the full sweep of the kick start lever. Quickly get your foot off the kick lever at the end of the kick to avoid any chance of "kickback" from the kick lever. This happens in the case of a misfire, aka > backfire. It can be very painful, and can even break a leg. I am serious about that. Repeat the process (but without the throttle priming), for six kicks. After six kicks go ahead and twist the throttle again for a second priming. A good battery, a clean spark plug, a clean carb and clean air filter will also aid in starting. Note that not all carbs have a power valve. When a power valve is not present you should crack the throttle open only 1/8 inch from closed on each kick.

Put in a new spark plug and check plug wire connections and ECM ground connections.

You probably have weak spark and when bump started the plug sparks strong enough to run the engine.

A weak battey can also cause this. Your ECM needs a minimum of 9V to work. (the ECM gives spark and timing) When kicking over, there is not enough volts to spark. When bumping over the alternator provides the extra volts to start the bike.

Hope this helps!

2005 250 f 65 kicks to start


Several things can cause the problem. First, spring for a new spark plug. The stock plug is NGK CR8E. Now the plug is eliminated as a problem. Next, pull the slide out of the throat of the carb. Now remove the jet needle. Put the needle clip on the 4th notch, (this is the stock setting). Use only premium gas. Next, follow the starting instructions below.

This will likely tame the beast for you. Please rate this answer. Thanks!
