Bummer mate...hope you get it sorted..

that makes two of us mate...

 

[roost666]

so barley any oil came out when you drained it, your supposed to keep oil topped up at all times, if its seized its pull down time to asses the damage

 

[TyD]

You need to take the stator cover off and get a 14mm socket and just turn
it over. That's what I done to my old one.

What TYD said... If you're lucky* you might find that it isn't actually seized and something else has gone awry

In the case that it turns normally from the flywheel you'll need to drain the oil again and start at the other side of the engine. Now is when you post as much information as possible... Do you know the engine model? If not, what gear pattern (eg, N1234), is it start in any gear, are there any markings you think will help people out... etc.

If it won't turn at the flywheel (or makes interesting sounds), it's time for a rebuild...

Good luck!

* Although I guess it depends on what the "something else" is...

Another thing to check is that the cam chain hasn't slipped off the cog. Will show the exact same symptons as a seize. Can be checked quickly too and is a much easier fix.

As Roost said, if there wasn't much oil in it then it probably won't be a good result.

its a ducar 124 (125)
anything else?

Check what I said first mate and cross your fingers. Just take the side cover off and you can tell in 2 secs. I had it happen to me once when I crashed into an enbankment. haha. Force knocked it off. Apparently doesn't take much on a yx140.

When I say bad I mean could just be a top end rebuild. But then it could be a bottom end that has gone or you have smashed your valves into the top of the piston.

EDIT: Can you please drop you signiture size? It's half a page almost!!

ok um what would be a guess for a price for the top and bottom end rebuild?
and about the signature...
not gonna happen!
hahaha joking sure thing mate!

better off just buying a new complete engine, it wouldn't be worth paying someone to fix it for you as by the time you pay for labor and parts it would equal about the same as a new engine

 

[krazed0451]

Depending on what you need to do... A piston and rings kit could set you back as little as $30

That said, it's best to check the basics that have been suggested and try to narrow down what the problem could be. If you've done serious bottom end damage, or even badly scored you barrel, you might be better off in the long run buying a replacement engine.

Hopefully it's a simple fix, but if it isn't, think of it as a chance to upgrade

** Beat me to it Roost

aaaah crap!
hope its only minor damage coz i dont have the money to buy a new engine unless i get some good money for the pw80!
if i do end up getting a new engine...
will a 155z fit? :b_grind: *evil laugh*
or even a 175z? if i ever win the lotto! :lol_hitting:

I'm sure if it doesn't slip straight in you could make it fit

You should be able to get ~$1k for the pw80... 175 time? ;-)

 

[wogtaz ryder]

put it in top gear , roll your bike back and forward without the clutch in . until it Free's up . if it doesn't .... well that's all i got. has worked for me a couple times .

If you do that and the cam chain ain't on properly you will shear all the teeth off the cog so be careful.

oh yeah! dont you know it is!
if i do get that sorta money for it first thing im doing is getting this: Z175 Engine

ok will try that but...

... ill check motormans idea first just incase

 

[dadof2]

the exact same simptoms as you posted minus the low oil happened to my first china it turned out to be a siezed engine
after adding up a rebuild i found a whole new engine was a cheaper /safer option

 

[pbk]

so did you get this sorted or find out anything new??

also if your thinking of putting a 155 or 175 in that i highly reccomend you save more coin and get an upgrade bike like a dhz or something... or even an atomik 160 and do simple upgrades

 

[atomik boy]

yeah ok so i got up breakfast etc etc
go the garage ok ill see if motormans idea was it...
...nope not that...
tried woggys idea to get it unstuck...
...well that failed...
so i tried ty's idea...
yep worked a bloody treat! (thanks man!)
i tried to kick it and it made a squeeking noise so i dumped the oil again and put more in...
still squeeked a little bit but not as much...
still not running hmm must be the cold air (0 degree's or some thing)
come back later...
wheeled the bike onto the grass no squeeking but still not running...
oh look i see damage! (see attached image)
hmmm ok ill strip it and see if there's any internal damage...
so i took it off the frame and took off the side covers...
nothing (exept oil)...
so i started putting back together and i decided to leave it 4 tommorow so now i gotta put the pegs back on and bashplate and if she doesnt run then ill wait till my auncle david (david johanson) gets here on tuesday...

hey also has anyone on here ever heard of david johanson or raced with him?
he does enduro's (well untill he moved back 2 the phillipenes)
thanks
