    Bairdco is right. We need more information. When you say, "She won't turn", does that mean the crankshaft will not rotate, or the engine will not start? If the crankshaft is seized then you have serious problems. If it just won't start, begin with the obvious things, Fuel, Air, and Ignition. Prove all three and get back to us with either more info or results of your tests. We'll try our darnest to help.

    I had one die on me like that, just 50 miles on the damned thing. I was idling and the engine stopped, then when I went to pedal start it, I couldn't pedal. The gears weren't locked because I could pedal with the clutch in, so I assumed that either the piston seized up or something broke inside the motor. When I pulled it of the bike I had to turn the engine over to get the chain off. It would not turn forward, but it would turn backwards! And the damned piston went up and down too!!! I can only assume that a bearing broke or came loose stopping it from going forward. It was under warranty so I never took it apart. You may want to pop it open and look inside though, you never know.

    My motor is upside down but my carb mounts rightside up - I went to start it one morning a few days after I got it , and it was ceased. Then I found out that gas leaked into the cylinder over night. When I removed the plug, gas poured out . I was really happy that it was not ceased. I blew out the plug, wiped it,put it back in, and it fired right up.:):):):)

    Blakenstein why do you have your motor mounted upside down and how did you mount it.

    Well Cabinfever, that's the way they designed it . Right now the system is mounted on my winter bike. There are pictures of it on page two in the pic&video section-second up from the bottom, titled "The Mud Hog my winter bike" that is the 35cc, and my 48cc mounts the same way. as a matter of fact, the gear boxes and auto clutches are the same size.:):) :-/

    Yea -sorry to hear about that. To me, ceased always meant one thing; The piston is frozen-the crank will not turn. Maybe it was oil starvation in an overheating situation.
    You dudes are right about there not being enough information.
    Ya know something funny? When I was young and ridding Ski-Doo ,I would always see the gas flowing back to the tank through the return line. My motor has a return line also but the only time I see gas flowing through it is when i push the primer button.:-/

    Thanx for the input guys,I was praying for a vapor lock situation....yes,no turn means No movement although im not sure if its the piston or something connecting to it...Oil starvation is impossible unless cold weather can make the mix seperate,several times she has died and was simply flooded.I need to see if the piston will actually move,its possible shes dead but I aint admitting that yet.....More later...Thanx

    Maybe your chain is bunched up under the clutch lever cover? Take off the cover & look at the chain.

    Venice is right, everyone of my 3 HT's have locked the chain after the "break-in" period when the chain has relaxed enough to allow for movement.

    good call, check to see if your chain jumped under its cover.

    I've often wondered if there were any other Trekkies here. Now I know there's at least one.

    Actually I hated the series. What with cardboard sets and Kirk ripping his shirt off and demolishing advanced races left and right. I was a fan of Space 1999. You know, the one that predicted we'd have cites on the moon ten years ago. :rolleyes:

    The fastest and easiest way to confirm whether your engine is locked
    up or not, is to remove the spark plug and roll the bike back and forth to here the piston move up and down. If it is still locked up, then remove the left side chain cover and look to see if the drive chain is bunched up around the sprocket. That's the most frequent cause.
