There is a proper way to start an engine. Most bikes have four controls to assist in starting.

  • 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.
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 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), until the bike starts. Go ahead and give it another primer shot after the 5th kick attempt. A good battery, a clean spark plug, a clean carb and clean air filter will also aid in starting.

I can't get my 06 crf 250 to kick start but it


the same thing happened to me its probably your valve clearance and need to be shimmed or if they worn really bad they need to be replaced..regarding roll starting your bike it damages your bike further and your engine could seize.

Hello,

This is a common problem depending on the area you live in.

Try this; quickly snap the throttle 3 -5 times and kick start it immediately. Do not open the throttle while trying to kick start your bike. You can open it about 1/4 of the way just before you kick start it, but let go of the throttle just as you kick start it - kick back sux and can hurt you.

You may have to run the bike a little richer (Carb adjustment).

Hope this helps. Please vote if this information was useful to you. Thanks!

I have a real hard time getting the bike started. When its cold i can kick it...but once it dies out I cannot rekick it I have to pop start it. Its also very choppy does not run smoothly.


Many of those CRF have problems with the valves, check the valve clearances, as well as all the general maintenance items, clean carb, clean air filter, new plug.
If the clearances need more than one number smaller on the shims, it may be the start of valve regression.

1. First thing is when was the last time you had your valves adjusted
2. On cold start up twist about 15 times on your throttle, as you do that the accelerator pump in carb will shot gas in cylinder, I have a 2003 yx426 & 2005 yz450 have to do to both of them when cold out to get started

My 2005 Crf 250 r will not start by kicking when cold if you roll it it will fire right up like it should runs great after you get it started the first time what are some simple things that i could try to...


Add water to the battery. Enough to cover the plates in each cell.
The battery may be on its' last legs. If you don't have a 1 or 2 amp charger, push start the bike and ride for a few hours. This should charge the battery < IF > it will still take a charge. If it won't take a charge and hold it then it's time for a new battery.

The reason you can push start the bike is that the flywheel is able to spin fast enough to generate enough current to provide spark. Kick starting won't do that. Just because a battery has SOME power does't mean it has ENOUGH power to do as needed.
