Honda 125 innova kick start problem

Picture a lawnmower. Pull the starter cable with the lawnmower on its side. Envision the movement being the same on the kick start. Removal of the cylinder housing requires removal of the starter arm. Many scenarios the arm connects to a gear with a bolt. Recommend bike shop. So as not to damage gear.

My ( 2008 Kawasaki Kx 100 ) kick-starter won't move down.. I tried Push Starting It and It's Seem To Lick The Back Tire... The GearBox Seem The Be Fine it's goes in neutral &' too gears 1-6 ... Also Moves...

Think you have simply frozen your piston from lack of proper fuel and 2 stroke oul mixture. Bike will move in neutral and with the clutch in, just won't kick or bumpstart ! Time for a top end rebuild my friend...good luck !

1974 suzuki ts 185 when you kick the kickstarter the front sprocket moves but the piston doesnt

i presume the bike must be in gear to move the front sprocket. does the piston move if try and bump it in gear..if not.the piston has somehow seperated from the krank, need a visual inspection, head needs to come of, possible more. if it does then need to look at kickstart mechanism

Well the motor locked up and i couldnt kick it at all shifted threw all the gears just fine but i wuz messing with it and i ran through all the gears trying to turn the back wheel and knock it loose didnt...

If you are running 5th gear mid throttle the compression in the motor wasnt enough to push the piston back down

for the record ( i run a ts 250 savage 2 stroke ) i,ve done it my self it happends

try to keep it the power band you will be fine

good luck.

2008 rmz 250 4 stroke i was riding it and all of a sudden it cut off and now the kick start wont move but shift through gears just fine i think the top end is locked up i'm not sure could the piston of...

Remove the spark plug, put the bike in fourth or fifth gear then try a jump start but with the key turned off. If the rear wheel locks up when you jump on and release the clutch then the piston has probably seized up OR the kick start-to-clutch hub gearing is messed up. The best thing to do is to remove the left engine side cover and look at the kick start mechanism. You may need to remove the clutch assembly for a full inspection. With the clutch removed the rotor ( crankshaft flywheel ) should turn. If it will not turn then a seized piston, broken cam chain or dropped valve is likely. If the rotor does turn then the kick start mechanism is the problem. Please rate my answer. Thanks!

Ii was riding it earlier and i shut it off then when i got back on it a went to kick it and the kicker was stuck it wouldnt kick. what could it be

The most common causes for this are a ceased piston (for instance, if there was an oil failure, the bike probably wouldn't have ceased until it was turned off) or if an internal bolt has gotten into the bottom end somewhere jamming the crank or kick mechanism itself.
Try removing the cylinders first, as that is the most likely cause of the failure.
If the piston is stuck in the cylinder, you may need to put a block of wood onto the piston and gently tap it out of the cylinder to effect repairs on the bike.
If the pistons come out of the cylinders without sticking, then having the cylinders removed will let you get a look into the crank area for loose bolts etc.
Don't forget to tie off the cam chain so it doesn't fall into the crank, because that's a pain to fish back out.
If you can't see anything wrong in the crank area, you will likely have to open up the bottom end to see what has gone wrong.
I wish I could be more help, but you didn't specify which bike you have.
If it's a 2 stroke, chances are the gas/oil mix was off or it ran out of 2 stroke oil and the piston ceased.

Kick starter has no compression, will not shift

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

Kick start wont move

Oooh that's bad, there are a couple of options. The best case senario is that your carburator floats got stuck down allowing the fuel to fill up the cylinder and exhaust pipe. This creates too much compression for the piston to move inside the cylinder. You can check this by pulling the spark plug (MAKE SURE THE BIKE IS OFF!!!) then kick it over. If fuel sprays out of the plug hole then you're in luck. If you don't turn the bike off first, the spark plug will ignite the gas squirting out of the hole and catch on fire... I know from experience. Tip the bike over and let it drain out of the exhaust and plug hole of the cylinder. If the kick starter will not move with the plug out then it's time to remove the flywheel cover. With the flywheel cover removed and the plug out, try turning the flywheel. If it turns then the kickstarter gears are jammed or broken. If it doesn't turn, then the piston or the crank is seized. Good luck.

03 CRF450 R push starts and runs, will not kick start.

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

I have a cr 125r and i have boared out the cylinder and put a bigger piston in it. i installed the pistion and new ring in the cylnder and it fit tight but was a good fit. i pushed the kick start a couple...

I assume you mean that you put fresh oil in the gearbox, not that you put oil in the cavity the piston rod is connected to. Putting oil in the crank area would cause a hydraulic lockup. The fix is to pull the cylinder then turn the motor upside down and dump the oil out. Flushing the crank with some gas wouldn't hurt. The crank and piston get lubrication from the oil mixed into the gas.

Position of the rod does not matter. If not a hydraulic lock up then only three things come to mind that would cause lockup.
  • A piston ring hanging up on a cylinder port.
  • Something dropped into the crank area and is now binding up the crank. Got all your sockets?
  • The bike is in gear.
Let me know what you find. Please rate this solution. Thanks!
