Kick start has no compression but runs fine once i get it going

They mean if you run it then remove it.

First thing is check your oil pump if function properly maybe sum damage on rings and pistons in your engine.

complete cylinder compression test. should be approx 120 psi
if low you will have to replace piston rings.

was bike running good before?

hi, will the shift lever shift up when the bike is being pushed along, is it stuck in neutral, if its in neutral then push it down make sure it goes into 1st gear then can u get someone to push u whilst holding the clutch in then release the clutch and see if you can jump start the bike that way.

when you push the kick start down is it turning the engine over properly and if so if the compression is really to low then the chances are the piston ring has broke and scored the side of the cylinder if this is the case then you need to get new piston and rings and a new cylinder.

The problem with moto x bikes is they are high power and work at really high temp so parts need changing more often the piston rings need changing every 25 to 35 hours of riding time you need to do this as they ware and brake if used any longer.

you also need to make sure you get the petrol and oil mixture spot on as if its not getting enough oil it will blow the piston and rings so you need to measure exactly the correct mixture.

these bike are expensive to maintain and need new parts on a regular basis so remember this the next time you get the bike running

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.

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), 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.

the bike might have to much oil in the bike so when you try to kickstart it, it sends oil to the piston and soaks the spark plug in oil. But when you push start it the spark plug is going alot so it catches, just kicking it doesnt give enough spark tho. my bike doesnt the same and then somtimes i have to take the spark plug out and clean it with a wire brush then usually its fine. Or you could have the wrong oil in the bike, i would read the maunal to find the perfered oil. hope this helps

It sounds like you cooked her. If you are jetted lean, and run it wide open for a long period of time, it melts the ring to the piston.
Do a compression test, remove spark plug, thread in gauge, and hold throttle wide open and kick untill the guage stops climbing (Around ten or so) Less than 100 psi is bad.

Could be low compression due to head gasket leak, worn piston rings. Or bad spark due to dirty plug, wrong gap, plug breaking down, lead or cap breaking down, ignition fault. Choked air filter, fuel filter.
Try these in easiest order I.E. remove air filter and see if it starts easier, do a compression test, cahnge plug, lead cap. Check the fuel filter.
I am sure it's a simple solution.(high milage engines tend to be difficult to start so take this into account)

It sounds like time to do a top end job. The head will need to come off, then the valves should be re-seated. Carbon should be removed from the head and piston crown. Since you did not mention any engine smoking, I assume the rings are okay. If you are going to do anything with the cylinder, piston and rings, now would be a good time. But remember, if it isn't broken don't fix it.

If you do the work yourself be sure to start with the piston on TDC compression. Note the timing marks stamped on the overhead cam. The piston and marks will need to be in the same position when reassembling.

Go to the site below where you can see a parts diagram for your specific bike. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site. In the event no price is shown on a particular part, the part is not in stock.

• If a hole in the piston then install new piston and rings. Next, clean the carbon off the head and install a new head gasket.
• If cylinder wall is scared the piston has seized up. Pull the cylinder off and take it to the dealer. Have them bore the cylinder and return it along with a new oversize piston and rings.
• While at the parts counter, get a new stock spark plug and a supply of Yamalube Two Stroke Motor Oil. You need to add 4 ounces per gallon when filling up. This will be a 32/1 gas to oil ratio. NEVER ride the bike without at least the needed 32/1 mix.
