Engine Trouble Seeking help engine wont turn over

I think your engine maybe seized. If you want to check unscrew the 4 large nuts on top of the engine. The head will slide off first (the part where the spark plug screws in). Then try to slide the barrel off and like V 35 said above it should come off easily. If it doesn't slide off easily refer to Fabians post above.
Seriously, scythyn has been making a lot of confused posts on the other
forum and your advice will have him mess up his motor more.

He didn't like or couldn't understand the answers over there so
know he is trying here.

I am not convinced his motor is seized.

Before you take the head and barrel off.

Remove the spark plug.

Pull the clutch lever in or remove the chain.

Remove the magneto cover where the wires to the CDI come out.

Take a socket wrench and try turning the nut on the end of the
crankshaft under the magneto cover.

If you can turn that nut your motor is not seized and the
piston will go up and down.

This is a lot easier way to check and he won't break his rings.

Yep do what MotorBicycleRacing says first. My advice is only once you know the engine is definitely not turning over and you want to see what the actual damage is.
 
ok i will do that now i will let you know how it goes. im a newb to these bikes. i didnt look up anything on it before i drove it(not thinking excited about having one) and now im just learning
 
may i just explain i thought at first it might have been a wire problem. i was 25 kilometers away from home. i put the clutch in and locked the safty and pedaled home. took me hours. i tried to start it a few times but it just didnt turn over. so it started with me believing it could have been the engine. i didnt think about what it wa first so i posted on another fourm re explaining the problem
 
i did find a loose wire when i looked at the cdi and magneto connectiong. they had just been clamped. i just got my new magneto and cdi(just in case) so im going to turn the engine over with a socket wrench and see what happens ill get back on it

What color was the loose wire?
How old are you? :D

take some pics of your motor and bike from a few different angles please.
 
ok so i took off the chain and turned he engine over with a socket wrench. i found that the nut holding the gear in place was loose so i took of the clutch side of the engine and unscrewed the flower nut and tried to tighten it. when tightning it back up i tried to put the pin back in and it wont go in

you didn't follow simple instructions.

making dozens of barely understandable posts all over 2 forums will
not get your motor fixed.

some people just aren't mechanically inclined enough to work on these
crappy little engines.

my advice is to sell your bike and motor for whatever you can get for it
and buy a Japanese scooter.

Good Luck! ;)
 
We all started ' somewhere ' I was lucky, first build ... new to gas bikes, but had 30 + years working on vehicles and power equipment,
so welding, paint, electrics, all came naturally. YES these bikes are a * pain * until you get to know them. Cruising the forums will give you lots of advice, keep a notebook to write tips down, you'll get many, and they will be scattered

Please be patient with us ' remote experts ' we can't see your machine, and can only logicly eliminate problems by guesswork, and past experience. If you wanted a scooter, you would have bought one. Don't give up, possibly start a second build, using experience gained from first one. I'll never forget my first ride, from one end of my parking lot to the other, what a bummer ! Took some tuning and patience, but got it to run well enough to know how bad it sucked. My second build had the virtues, but not the vices, was easy to do, and ran well.
 
Although they are a basic design, these engines can be a serious pain in the backside when they want to misbehave and play mind games with your head.

Sometimes it's just more efficient to start the day all over again with a new engine, especially if you are new to the game.
