Hey guys got back from a gnarly one today and outta the blue the kick starter is seized up. I know this is not good at all, can roll it either. My clutch seems to be intact so do you think the crank seized? My nambo has maybe 20 hours on it so I'm very confused any help would be great!

I assume you mean you 'can't' roll it over. Take the spark plug out and try to turn it over with the flywheel when in neutral. That will tell you if it is crank/piston related.

Take the exhaust off and have a look at the piston.
 
ok well thanks alot keg i took the plug out and spun the wheel in gear cause kick was still siezed and it is moving freely again, if you dont mind can you explain what you think happened?
 
i went out and put the pllug back in and it didnt want to kick but i reefed on the kick and it let go and she started up.do you think something was jammed in the silencer?
 
With the plug out, did the kicker work?

Just trying to work out if the piston is seized or the kick starter is an issue. If you can turn the motor by the flywheel with the plug out, I would think it is clutch, kicker or gearbox issue.

If you have just un-seized it now by swinging on the kicker, I would be pulling the top off it. For the price of a bit of coolant and 2 head orings, I would be having a look....after you have had a look through the exhaust to see the piston.

I blocked muffler wont stop a motor turning over.
 
yes with the plug out the kicker worked but not initially i spun the rear wheel first then tried the kick starter again and it moved freely, i then put the plug in and it seemed stuck at the kick starter and then it just released. i kicked it over and it fired the first time. i went down the block with it went through all the gears and ran like it always does?
 
ill also add that when this first occured i was at the top of a hill and from a roll it wouldnt jump start, the rear wheel would just drag.
 
My 125 did something like what your describing, wouldnt turn over at all, wouldnt bump start, nothing. Pulled the stator cover off, turned the flywheel backwards by hand, and it freed up. Started fine and ran for over 50 hours before the piston shat itself, so considering the gap of time between it locking up and the piston failing, I would say they were unrelated other than the fact that it was the same bike.
Oh and I pulled the barrel off after I got home and the piston and ring were fine.

If you have pulled he head off and the top of the piston looks fine, myself personally, I would pull the barrel and look for any marks on the cylinder wall, and on side of the piston, if it got hot any seized temporarily then there will be evidence of it on the piston.
Also, if you wanted to be extra safe you could pull the primary cover off to inspect the clutch and kickstart mechanism.
 
He just wanted you to take the pipe off so you could have a peak at the piston back in there. You need to not ride it any more. If there was coolant in the bike then you have problems. If you didn't have coolant it may last, but I doubt it. Either the bike got hot and the motor seized or a hunk of piston or something broke off and is hung in the motor. At the very least you are talking a piston and rings, and at worst....well, lets just hope it only needs a piston. To be honest, you don't sound like you have been into engines before. This bike is easy, but you have to have some knowledge of how things work. Have a buddy that can help?
 
The plug being in/out has nothing to do with turning the motor over and is just a coincidence. I'd eyeball the cylinder and piston through the exhaust port, if all looks good and compression is good I'd have that primary cover off and look for something backed off that jammed the system. If all is well in the primary then pull the top end for a closer inspection and inspect the lower end.

Something went very wrong and will not fix itself. Have you drained your trans oil and checked the plug magnet? This may tell all.
 
i had a kx100 do exactly as you describe, the rings caught the exhaust port and put a big gouge in the plating, and scored the piston and cylinder.
 
ya my buddy wtec(wes) told me he thinks its kickstarter mechanism and to drain tranny oil. im going to consult him and see what he finds but will look into all you guys have helped me with, your right i have little experience with 2 strokes, ive only ever had 4 strokes before this so your advice is invaluable. i will check cylinder tomorrow and drain tranny oil. i will let you know.
 
ok so i drained oil and no chunks or anything out of the ordinary, i checked the piston and there isnt a mark on it and the cylinder has no scoring or gouging of any kind it looks perfect. im going to consult my dealer to have a look behind the primary as i dont think this should be happening with only 25 hours on the bike. ill post a pick of the cylinder shortly. oh and there was no coolant in there either.
 
im no expert,but that piston top looks too clean,ive seen pics where the coolant has been into the cylinder and cleaned the carbon right off the top of the piston
 
Nambo, my 2004 DE200 stalled while riding one day and then it would not kick over at all when inspected one of the stuffer plate screws backed out and got lodged in the bottom end.
I had some pictures as soon as i can locate them i'll try to post.
 
thanks for the help id like to see those pics if you can locate them. were you able to start your bike again until you replaced the bolt? just wondering because mine is running completely fine now. i know something has had to happen to make this occur but ive checked half of what everyone told me to do and so far it looks all good. if i get the primary cover off and nothing is backed off and there is no chunks of anything causing problems do i just go back to status quo and ride it? its tough when you dont find problems because the bikes brand new and i dont want to be rebuilding after 4 rides.
