Need more input.
Typically a two stroke engine will have the piston seize in the bore due to too lean a mixture of either petrol or oil.
The road racers of old would always have two fingers on the clutch, just in case. But as happened to me, the engine seized as I was going around a corner. That seizure was from a piece coming off the end of the crank and jamming against an engine case.
Sometimes a gearbox will seize, or a primary chain will jam and seize the engine.
Maybe a bearing in the middle gear drive seized.
Or are you talking about a motor that has been sitting outside for a few years with the spark plug out.
I certainly need more input before any reasonable response from me.
Then of course there is a brain freeze.
- Unkle Crusty, I must apologize for jumping in this conversation, but I also have a probable seized engine on my 2009 Honda Rebel 250. It has 14,000 miles on it. The bike was well kept and well maintnanced untill this past year. I neglected it by not properly checking the oil (and it did run low a few times, low meaning a half of quart once on a 2 hour ride and it should have been changed around 3000 miles ago, anyway, I pulled it in to my kitchen last fall but did nothing to it until today. So I emptied the gas tank, rinsed it with gas treatment dtied it put it back. I also put a new battery, new plugs, and changed the oil. I tried to turn the motor over a little for the oil change but it wouldn't turn, at all. i thought maybe new battery a little weak, so I tried rolling it off. I rolled it off alot last year, thats why the new battery this year. No matter what gear or how fast I was rolling, every time I released the clutch it would act as if I hit the back break. The back wheel would not roll at all not even an inch. I am a 54 years old woman and could fast walk it and it would start easily last year. So I am left to believe the engine is seized. MY QUESTION IS. What should I do next? I am familiar with basic repair and want to do this " right", I don't however have much knowledge about the internal parts of an engine. But based on your previous response, I was hoping for some advice if you would be so kind. I apologise for the length of this message, but I thought the leaset I could offer was the history detail so that it might offer some insight on the situation. Thank you so much for even considering it. My name is Traci Bunch I live in Tennessee Thank you again
