Should a sa50s motor spin over easy by hand?

Picked up a 1995 elite 50 8 k miles,and have not gotten a battery yet, while I have it apart, The motor spins over easy by hand..Is this normal for these little motors? I can't do a compression test till I get a battery...Just wondering if it should spin over fairly easy.

How long do these motors last before needing a top end? milage?

Thanks

with the spark plug out? or in?

8k miles! dude it is totally time to get a new set of rings.(or a new cylinder and piston if they are trashed)

If you have the plug out it should turn over easy. That is good. But if the plug is in it and it turns easy by hand, you need a new top end.

Plug is in, I will have to do a compression test when I get a battery. It does start and run good..

Thanks,

I have not even been on it yet, It needs a battery. I have HAYABUSA battery I jumped it with to see if it would fire. That is as far as i got. But while I had the body off, I noticed I could spin the motor over very easy by hand.. I will do a compression test tonight when I get a good battery.

120 LBS of compression. It starts easy, Runs a few minutes, Then stalls. Will restart easy but will not take any throttle. None at all.

clean the carb about 10 times. Then 5 more after words.
It should run with that kinda of PSI.

I have it on my lift and when I started it for the first time it was with out the air filter and cover. I just bought it and was just seeing if it would run. I did not have the in becayse it was falling apart . after talking to a few people, turns out this motor does not like to be run with out the filter and cover.

Just ordered the filter, I will wait till it gets here to try it again with it installed to see if that was the problem.

Thanks,
