You better check that 2 stroke motor they usually have the mounts on the bottom of the motor the 4 strokes have the motor mounts on top. If so it will not be a swap. Also that motor is loosing compression badly. Have you checked to make sure it is timed and the flywheel woodruff key was not sheared and is way out of time. Have you checked the compression on it, I can hear the compression being let out. Is the plug hole stripped or anything. Have you checked the valves and make sure they are sealing.Alleyoop I'll check it out tomorrow. Thanks for the feedback

Though so, my other engine is the kind you have to mix oil yourself in the gas tank.. as it has now spot for the oil on the right or anywhere...

Have you ever swapped one? It's a piece of cake. I did it in two hours once including lunch. The engine is not that heavy but a floor jack helps. If you need help we are here. I'm gonna see what I can do to get that video on here asap. I have another project at hand remodeling an rv haha. I'll get that video asap.

HAHAHA, so you bought it used with 7k miles on it and you only have put about 150 miles or so on it. Well here is the thing if it starts up nice and easy and idles nice and on the center stand it revs up good then I would suspect the problem is in the CVT and not the motor. But I can tell by the sound of the motor if it is weak when you twist the throttle and I also need to see how the rear wheel is spinning when given throttle. It would be very easy to find out if ONLY for someone to hold the bendix in place and starting it and watching how the cvt is working with the COVER off. Now some have wired the BENDIX in place to hold it so no hands or used I will try to find the picture of that shot so maybe you guys can do that and have it for use later on. Alleyoop FOUND IT: See the WIRE WRAPPED AROUND THE END OF THE BENDIX SHAFT do that and then start the VIDEO and we can watch the CVT working or not working right and we will be able to tell right away what part is bad. Now you can wrap the wire around it and actually then just hold it back with your hand above the cvt and away from any moving part. Or you can do it like in the picture he used the bolt and hold to the right of it that holds the cvt cover on to hold the wire on. Ok. I will have to do it tomorrow as I was busy all day. The motor sounds extremely bad so I believe that to be the problem.

You called that quite awhile ago Alley ,,, what threw me was ( if memory serves) the engine was not revving but slowed when the bike was slowing,,, if the engine is revving freely and it's slow you again called variator/ oily belt/ bad clutch / blown final drive,,, not much else left really I'm the the hitler baby... haha heard that one yet? I know I was the first to call Alleyoop bugs bunny before I remembered the name. anyway.. thanks guys, I'll try to get a video asap.

If the motor sounds good and it runs good It may be the Variator hanging open and not closing that would give you MOTOR REVS but no mph. In the 7K miles it has have you every changed the weights and plastic guides in the Variator. So if the motor sounds good and it revs then THE next thing to do is TAKE the Variator off and inspect the weights and guides and it may be all that is wrong with it. Alleyoop I'll try to get a video in the day. I got the scooter at around 7k miles.. its now about 7,150. So I don't know much about it. It sounds really bad though. My dad says its done with.

Wait a minute What makes you think the motor is shot? Does it turn over have you checked compression if it turns over and has compression then it is still alive. To check compression without a gauge take the spark plug out and stick you finger in the hole and hold it nice and snuge then HOLD THE THROTTLE WIDE OPEN and crank it over. IF IT LIFTS your finger off the hole it has descent compression if you just feel a little pressure then it has low compression. And 7K miles is really not a lot the motors on these scoots usually fully break in around 2K. I started it.. still pulling the gas, drive it a couple feet at full throttle. It went like 5 miles per hour at the most, maybe 3 mph.

YES, drain it and fill with new oil. That could be why it slowed down on you the oil is to dilluted and it got to hot and got a soft seize we hope and did not do internal damage to the motor. Alleyoop Did that. The motor is gone. I'll probly switch it out. It makes sense. It has over 7k miles.

Yes the dipstick when you screw it out wipe it off and then just stick it back in do not screw it in and pull it out. Oil should be seen on the XXXXXXXX's if oil is on the XXXXXX's your good. If no oil is present on the XXXXX's then you need to add some oil to cover at least half of the xxxxx's when you stick it in without screwing it on. I think my gas got into my oil.. the oil stop by the muffler is over filled.. all the way to the screw hole. And it smells like gas, shall I drain it and fill in new oil?

Well if it is dry then not a problem. Is the belt dry and not have oil on it then it is not a problem with leaking oil in the cvt. But you do want to clean it out so you can see the shiny metal behind it. What happens is with the heat it creates as the belt wears and heats up it sort of melts the rubber part of the belt and it sticks to the inside of the cover and the back cover. So clean it out before you go and put it back on get a roll of paper towels and wipe that stuff out. So NOW check the OIL LEVEL in the Crank Case. Do you know how to do that? If oil level is good put the cover back on and ON THE CENTER STAND see if it will start the rear wheel turns when giving some throttle. Do you mean the dipstick? If so, how full should it be?

If there is OIL in the CVT cover this would be the suspect another suspect would be the Chain Tensioner bolt holder which is to the right of it. So I checked and there is a bunch of dirty oil that is dry in the cover.
